PC Clients w/Yosemite Server

Our office is running Yosemite Server (10.10.2) on a Mac Mini Server (late 2012). We have both Macs and PC's (Windows 7 Pro & Windows 8) using the Server. Occasionally one of the PC clients will not be allowed to save to the Server. I get onto the Server and reset the Permissions for all of our shared files and the problem goes away for awhile. Does anybody have a solution to this?

Any jabber client will do. Head on over the the source for options:

Hope this helps

Connecting Ubuntu client to Yosemite server VPN

i have searched for info on this and all I have found are other unanswered questions and links to non OSX server solutions. Surely connecting a Ubuntu PC to an apple network via VPN is commonplace? Not often you still find the Mac vs the rest of the world problem nowdays. Thanks, Alex

Hello. Apologies for bumping this question but there are quite a few unanswered questions on the internet relating to this. I seems illogical to me that it is not straightforward to link a Linux machine to an OS X server network remotely? Surely this is relatively easy and I have got the wrong end of the stick somewhere? Thanks for your input. Alex

Can log into Yosemite server (4.0) VPN service with a Mavericks client, but not Yosemite client

Sever Info:
Yosemite Server 4.0 running on a late 2009 Mac Mini with 8 GB RAM with vpnd service enabled
The server was upgraded to Yosemite - not clean install - this may not matter (see below)
Airport extreme router with standard VPN UDP ports for L2TP forwarded to server (500, 1701, 4500)
Client info:
MB Air 13" early 2014 with 8 GB RAM
Yosemite
Mavericks 10.9.5 running as a Parallels virtual machine (don't ask - I need it to run an app for work that is not yet compatible with Yosemite)
OD service is NOT running - no VPN connections ever occurred from ANY client with this service running - OD is not needed in my case fortunately
With the OD service off, I can connect via the Mavericks virtual machine just fine, but not with Yosemite. With Yosemite, the ppp connection appears to occur, but server config requests appear to fall on deaf ears (client side doesn't appear to respond) until the connection times out. Can't figure out what triggers the client response to a server config request. Client side complains about no route to host and IP addresses don't get assigned to the connection.
The connection happens successfully in an eyeblink with the Mavericks client. Same username/password/shared secret in both instances.
Tried a generated .vpnconfig from the server, this also did not work.
It's possible that it is an auth problem, but can't figure out how the process occurs or what may be going wrong. There does not seem to be an obvious way to increase the granularity of the logging such that it might give other hints - at least that I can find. I found plenty of references to VPN issues when people upgraded from Mountain Lion to Mavericks as well as work arounds for this. I tried the most promising looking of those - no love. I reverted everything back to stock install since I could at least connect with Mavericks.
If log entries would be helpful, they are included below. I've stared at them long enough - perhaps a new set of eyes can provide a hint.
In addition, I can find no documentation regarding the VPN service in Yosemite server so as to get a clue as to whether there have been changes in racoon since Mavericks.
Thanks in advance for any suggestions. I would be glad to supply any other info needed for an accurate diagnosis .

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Yosemite server: no CardDAV-Sync with Yosemite clients

Hi everybody,
this drives me really mad:
We had a Lion server (older Mac mini) with Calendar and Contacts services running with no issues. We used global accounts to share company's events and contacts between Macs and iOS devices.
We started using Yosemite on the clients. Even two new clients (iMac and MacBook Air) came into place with Yosemite already pre-installed. Again: Everything works together.
We bought a new Mac mini to switch to Yosemite and OS X Server 4. We didn't any migration and started from scratch: DNS, Open Directory etc.. On one client machine (Yosemite) we just exported the calendars into *.ics-files and the contacts (groups) into *.vcf-files.
On the new server we created network accounts with an exported text file and NOT via an OD archive of the old server, the new server has a different hostname/IP address, both servers didn't disturb each other.
The migration took place at one client again: Importing each *.ics-file into the new account works as expected. Every appointment or event was then synched to every client (OS X, iOS) from the new server.
But: While importing the contacts into the global network account of the new server seems to have been worked, the syncing down to the Yosemite clients breaks and didn't finish. Mavericks clients and iOS clients sync within a few seconds without any problem: They have the same amount of contacts and groups. The Yosemite clients sync far longer and are missing about 100 or 200 (it differs from machine to machine) entries and do not show any group at all.
Even a completely new created local account with fresh configuration of Contacts.app shows this behavior on Yosemite clients. But ONLY with the new server.
This is really strange, isn't it?
Has anyone got similar experiences? And solved this issue, probably?
Best regards,
Olaf

I am experiencing a similar problem with both CalDAV and CardDAV. The existing accounts seem to work as long as you don't try to add a new one. When you try to add a new CarDAV or CalDAV account, a OS X Server account is added instead. The new account gives you the options of selecting Calendar, Contacts, etc. but it's not working. I'm not sure how to work around this yes, but Apple Support suggested copying the files from a working Library into the one that is not working, but I have not had success doing this. This is a known bug that needs to be fixed. If you figure out a work around please let me know [email protected] thanks.

Reconfigure Open Directory in Yosemite Server

Is it possible to delete and reconfigure Open Directory in Yosemite server?
The host name and configuration were modified after Open Directory was activated and I get the message "Unable to load replica list" in the Settings Tab of Open Directory on the Server App (Server 4.0.3 (Build 14S350)). I think the best way would be to start over the automatic configuration.

Many Open Directory problems can be resolved by taking the following steps. Test after each one, and back up all data before making any changes.
1. The OD master must have a static IP address on the local network, not a dynamic address. It must not be connected to the same network with more than one interface; e.g., Ethernet and Wi-Fi.
2. You must have a working DNS service, and the server's hostname must match its fully-qualified domain name. To confirm, select the server by name in the sidebar of the Server application window, then select the Overview tab. Click the Edit button on the Host Name line. On the Accessing your Server sheet, Domain Name should be selected. Change the Host Name, if necessary. The server must have at least a three-level name (e.g. "server.yourdomain.com"), and the name must not be in the ".local" top-level domain, which is reserved for Bonjour.
3. The primary DNS server used by the server must be itself, unless you're using another server for internal DNS. The only DNS server set on the clients should be the internal one, which they should get from DHCP if applicable.
4. Only if you're still running Mavericks server, follow these instructions to rebuild the Kerberos configuration on the server.
5. If you use authenticated binding, check the validity of the master's certificate. The common name must match the hostname and domain name. Deselecting and then reselecting the certificate in Server.app has been reported to have an effect in some cases. Otherwise delete all certificates and create new ones.
6. Unbind and then rebind the clients in the Users & Groups preference pane. Use the fully-qualified domain name of the master.
7. Reboot the master and the clients.
8. Don't log in to the server with a network user's account.
9. Disable any internal firewalls in use, including third-party "security" software.
10. If you've created any replica servers, delete them.
11. If OD has only recently stopped working when it was working before, you may be able to restore it from the automatic backup in /var/db/backups, or from a Time Machine snapshot of that backup.
12. As a last resort, export all OD users. In the Open Directory pane of Server, delete the OD server. Then recreate it and import the users. Ensure that the UID's are in the 1001+ range.
If you get this far without solving the problem, then you'll need to examine the logs in the Open Directory section of the log list in the Server app, and also the system log on the clients.

Permissions are not displaying correctly on Yosemite server

My file and folder permissions are not displaying correctly on my Yosemite server when viewed from a Yosemite client.
I have set these permissions from the server app on the server and have added local network groups for the appropriate folders on the share. When checked from the server's finder, everything looks correct. The server is setup for both AFP and SMB on file sharing. I have also tried setting permissions from the server's finder and seemed to make no difference.
When logged into from local or VPN Yosemite clients using AFP, the permissions do not show anything but postgres user and everyone group. Even though they should have network groups such as skoogfinancial, skoogmarketing, etc.
The server does seem to enforce the permissions correctly though a user cannot get into folders he does not have permissions for.
Therefore, it seems the server is enforcing correctly, but a user may not understand what is going on as the permissions list doesn't list anything meaningful.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
*Note: If FileVault is enabled under OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

How do I define server-side spam rules with Yosemite & Server 4

Really surprised that this isn't functionality available in the server UI. Poking around in the dovecot/spamassassin docs imply this is possible using sieve, but the configuration looks more complex than I'd like to have to figure out on my own. It seems that sieve might be possible to use. In /Library/Server/Mail/Config/dovecot/conf.d, the option sieve_dir is uncommented, pointing to /Library/Server/Mail/Data/rules/%u. That seems to imply I could create user directories there and apply some sieve rules, has anyone tried this?
I'd rather not do user-specific rules, I'd prefer to use the default and attempt to move all spam into a spam folder for each user.
I've seen notes that the webmail client Roundcube provided server-side rules, but I really don't need the web mail client, and various search results seem to raise questions about whether Roundcube is compatible with Sever 4 / Yosemite.
Any help would be appreciated...

Was able to get it working with some digging. The basic summary is that you need to create a rules directory for each mail user, and then add a sieve rule in each of the directories you create. I did this manually, which is manageable because I'm using OS X server for my household, and we don't add members to my household that often... :-). Summary of the steps:
1) Each user has a directory in /Library/Server/Mail/Data/mail that is in UUID format (long hex string with sections broken by - characters).
2) For each of the users you identify in (1), create an equivalent UUID directory in /Library/Server/Mail/Data/rules
3) Create a file named "dovecot.sieve" in each of the directories you created in (2). For a basic rule that moves mail marked by SpamAssassin as spam to the Junk folder that Mail.app should create by default, you can use the following:
     require ["fileinto"];
     # rule:[SPAM]
     if header :contains "X-Spam-Flag" "YES" {
             fileinto "Junk";
4) Ensure that all of the directories/files are owned by _dovecot. I marked dovecot.sieve as executable, but I'm not sure that was necessary.
5) Once you've done steps 1-4, you should start to see evidence that sieve is being used for delivery of mail in /Library/Logs/Mail/mailinfo.log. Grep for "sieve" in that to see activity. If there are errors, you'll likely see notices that there are sieve logs being created in the rules directories you set up in (2). I ran into errors for at least one account that didn't have a Junk folder created; if you hit that just have the user create a folder named Junk to clear it up.
Hope this helps others...

Yosemite Server: Apache shm errors with proxy_balancer | SASL errors using user alias

Dear OSX Server Ninjas,
I recently upgraded my 10.9.5 Mac mini running Server 3.2.2 to Yosemite + Server v4, directly to v4.0.3. The box serves the whole Mail/Cal/Contacts/VPN palette as well as some websites, Git repos and some custom software. See below for network setup.
After battling the most blatant issues (some easy to fix but hard to find, others hard on both), I'm almost back to a working server setup … but some things keep bugging me even after days of log-reading and OD tricks. In the last days, I have read countless discussions here as well as on stackoverflow/serverfault/apple.stackexchange and blogs, so I'll try to be as thorough and precise as possible to show what I have tried so far – sorry in advance for the long post
… and since you might not read to the bottom: Thanks in advance for any help, especially with the Apache problem!
My setup
OSX Server v4.0.3 running on Yosemite 10.10.1 ➞ both latest official releases
host + DNS
Hostname configured for public domain mydomain.net, web traffic on selected ports comes in through router NAT
Server has a static IP on the local subnet 192.168.178.0/24
Server running local DNS and performing lookups for all clients in the local subnet, forwarding to the router at 192.168.178.1
Primary zone for mydomain.net with records (A, NS, MX) pointing to said static IP
changeip -checkhostname is successful
Public IP is currently configured at the domain registrar through his name servers
SSL
Trusted third-party certificate installed for host.mydomain.net (Common Name + SAN for two subdomains)
Used to secure all services
Qualys SSL Test Grade B (capped due to OSX's openssl 0.9.x not being capable of TLS1.2 and Intermediate CA SHA-1 )
TLS working both inbound and outbound according to CheckTLS.com
OpenDirectory
Recreated after upgrade (probably not necessary, since issue persists), re-imported groups + users from WGM backup files
Only the server itself is bound to the directory, other devices just access services through network accounts (CRAM-MD5, MD5-Digest)
Problems
Apache shm errors: Apache fails to create slot memory when proxy module is enabled
As soon as I start a service which requires the Apache proxy_balancer module (e.g. Cal/Contacts, ProfileManager), this starts filling up my Apache's error log:
[Mon Jan 12 01:41:17.979882 2015] [proxy_balancer:emerg] [pid 2949] (28)No space left on device: AH01179: balancer slotmem_create failed for p26d9e669--1011640492

[Mon Jan 12 01:41:28.297355 2015] [:emerg] [pid 3026] AH00020: Configuration Failed, exiting
When I increase the Apache LogLevel to trace1, I get this as well:
[Mon Jan 12 02:11:43.190303 2015] [slotmem_shm:debug] [pid 5501] mod_slotmem_shm.c(367): AH02602: create didn't find /private/var/run/slotmem-shm-p26d9e669-813569972.shm in global list
This causes the Apache to crash constantly, which is … unnerving. After googling around for a while, I tried the following steps:
Stop Services that use the Apache (Web, *DAV, ProfileManager)
sudo apachectl stop
Remove all orphan cache/slot files (.shm, ssl-cache, proxy.*) from /private/var/run
Reboot the server
Start up the Services again
Curiously enough, this worked for a while! But I was getting several log messages about dropped proxy connections, and sometimes the ProfileManager page would time out. Then, the issue started to reappear and does not seem to be fixed again with the steps above. I looked through the Apache config files and config plists for the Services in question, as well as the default config files. The only thing I have so far is that as long as there are no active proxy connections, the Apache runs smoothly – but all goes awry when slotmem files are created (a lot of them). Sometimes, I am able to turn on the Calendar service, but switching on Contacts produces the error … one time, I even got Calendar + Contacts running, and all went well until I enabled Profile Manager.
I found several error reports with similar or identical errors from other Apache 2.4.x users, but most of those were developer talk on mailing lists, or suggested steps that did not work for me (or were inapplicable on the OS X Server Apache environment).
SASL errors using user alias for WebDAV-Digest authentication
Short version: I am unable to authenticate through WebDAV-Digest with a user's alias (defined in Server Admin > Users > Context Menu > Advanced Options or WGM). Using the main short name of the same user works flawlessly. Password Server Error log just shows:
AUTH2: {234023578237md5hash2384234, mainshortname} WEBDAV-DIGEST authentication failed, SASL error -13 (password incorrect).
The password is 100% correct: When I set up a test CalDAV account and put in alias+PW, it did not work (OS X Dialog showed “could not be verified”, Server log as above). Leaving the password field filled and just switching the user to the main short name went through instantaneously, with the Server log showing
AUTH2: {234023578237md5hash2384234, mainshortname} WEBDAV-DIGEST authentication succeeded.
Notice the same MD5 hash and canonical short name, yet different results. I don't know if this is a new “feature”, a result of mail aliases being handled differently (at least I read that somewhere) …
Additional Questions
Should I configure the DNS for public use, instead of the Split-Brain configuration (local network gets local IP, outside traffic is directed by registrar NS)? I read several articles explaining that Split-Brain is common in large organizations, but might introduce weird networking issues. Entering the external IP as a Round Robin alternative for the internal does not seem sensible to me.
I also have a question concerning LDAP log entries like this one below, but I'll put that in this already open discussion:
=> bdb_idl_delete_key: c_get failed: DB_LOCK_DEADLOCK: Locker killed to resolve a deadlock (-30994)

Today the same error occurred on a customers server.
We don't use Calendar or Contacts.
We only have some websites configured and want use NetInstall for deployments.
As soon as I disable the Profilemanager the httpd starts over and other websites and NetInstall via HTTP are working fine.
When I reenable Profilemanager the httpd processes are gone and I see the same stuff in Apache's error log...

Yosemite Server Vs. Windows Server 2012

Hello, I wonder does Yosemite server can replace Windows Server 2012 and work as full as server operation system?
In services:
DNS
DHCP
Webserver
FTP
Mailserver
Maybe Virtualization

We found the same. One small Mac mini replaced a towering Dell, tripled the uptime of our UPS and the Mac Server could not have been easier to configure. It almost fell into operation with all the services you mention. We don't employ an IT department or external contractor to manage this either (we are all electrical engineers here though...)
Biggest benefit other than stability, ease of maintenance? TIME MACHINE - for us - this is worth its weight in gold to have such a simple and effective backup strategy.
But..... We have found some issues with the SMB (File serving / File sharing) functionality from windows clients.
Files that are open on an SMB share from a Windows 7 client, all our users eventually complain that the file/s they have been working on and had open for 2 hours (some shorter some longer) suddenly becomes read only... And they no longer have permission (even though they created it, have group privileges etc) to delete, move, rename etc. Strange things happen with file locks too, so the file can report it's in use when the owner tries to open the file after closing the app and starting again. (problems are related obviously) Only the admin can change it... (doesn't matter the app or format - CAD, Word, Excel.... or MYOB accounting files! etc)
We ended up running a W7 instance in a VM and handle the critical file sharing out of there. (Could have set up server 2012 in a basic mode - but seems mad to have 2 full servers. Had other reasons for wanting the W7 VM anyway - so no big deal, but less than ideal for a "file" server.
If anyone has ideas - about what might cause the crazy permissions issues - happily discuss - but other than that - OSX Server is a great choice for us.

Yosemite Server Mail GSSAPI Error

Since upgrading client machines to Yosemite, connecting to mac mini server running Yosemite (server v4), I'm seeing this error in the client main log file:
22/10/2014 12:43:56.579 Mail[7452]: GSSAPI Error: Miscellaneous failure (see text (No credentials cache file found (negative cache))
22/10/2014 12:43:56.579 Mail[7452]: Failed to start the SASL connection
SASL(-1): generic failure: GSSAPI Error: Miscellaneous failure (see text (No credentials cache file found (negative cache))
Has anyone else seen this or have any thoughts as how to proceed? Thanks a lot for any pointers in the right direction.
(ps mail is being sent and received)

Hi,
maybe it helps or not, I solve a other performance problem which is more related to the mailbox speed but this error on client side is gone afterwards:
In Yosemite there is still also a problem with the automatic settings detection in Mail.
That means that the application try's to find a working authentication mechanism in combination with different ports and encryption.
So far so good, this feature would be okay but the application never stops to do that. So we are shortly connected but the connection becomes invalid again.
This leads to performance issues and the application becomes very slow!
If you refer your client log file maybe you can see some "Failed to start the SASL connection" issues (coming from Mail.app).
In case that you are running a OS X Server which is used by Mail you will see in /var/log/mail* /Library/Logs/mail* various login failures. In case that you have enabled the Adaptive Firewall it can be happen that your IP is blocked for 15 minutes.
Of course this must not be a issue for everyone I believe it strongly depends on your email server / provider which auth. stuff is supported or enabled.
To solve it:
1.) Open the Mail Preferences
2.) Goto "Accounts" and select your Provider/Account
3.) Klick Enhanced (the last right tab)
4.) Disable the automatic settings detection (first checkbox)
5.) In case you didn't enable "MailDrop"
This works in Mail 8.1 on Yosemite 10.10.1

Yosemite Server: After upgrade, OD is read-only

Hello,
yesterday, I upgraded my server installation to Yosemite and Server 4.0. Although it seemed that everything went fine, a severe problem turned out.
Symptoms:
I cannot login to network accounts from other machines, although Directory Services show the right content for each user. Assumption: Kerberos authentication fails for unknown reason.
Then, I discovered that OD on the Yosemite Server shows all Users and Groups, but I cannot edit any of them; any "change password" or similar context menu options are grayed out.
I had the "fix permissions" run and reboot, but without any effect.
As it seems, the /Library/Server path content is considered as read-only for the Server app; this impression is supported by the RADIUS service: When keying "radiusd -X", this is the result:
Starting - reading configuration files ...
including configuration file /Library/Server/radius/raddb/radiusd.conf
Unable to open file "/Library/Server/radius/raddb/radiusd.conf": Permission denied
Errors reading or parsing /Library/Server/radius/raddb/radiusd.conf
Any idea how to fix this? I'm not the hardcore sysadmin, so I'd appreciate any kind of help...
Thanks a lot in advance!
Best regards,
Hardy

Addition: I just found out that a login request from a client to the read-only OD leads to these system protocol entries:

Could be the DNS as Lync Davis writes but to elaborate somewhat:
It's not enough to have the DNS in the server itself. At a standard setup that will only be used by the server to find itself. Senders must also be able to look up the mail server's full domain name which means that you must have those records in a public DNS server so that clients sending mail can look up the server. Local clients might get settings via DHCP to use it as DNS server and if it's accessible from Internet on port 53 it could be used as a public DNS server (set in the settings for you domain at the registrar, by them or yourself).

Yosemite Server Mail and Google Domain Relay

I want to simply use the server to send automated emails from scripts. I have server installed. Over the course of two days I've have followed several posts:
http://www.anujgakhar.com/2011/12/09/using-macosx-lion-command-line-mail-with-gm ail-as-smtp/
http://blog.anupamsg.me/2012/02/14/enabling-postfix-for-outbound-relay-via-gmail -on-os-x-lion-11/
And the updated Yosemite version here:

Yosemite Server configuration
http://krypted.com/mac-security/configure-the-os-x-yosemite-server-mail-service/
I've gotten no where. In my last attempt all sasl errors and no mech connections had stopped but mail did not appear to go anywhere. No trace. I stumbled across a post that said ssl connections from Mac OS X Yosemite are broken and just don't work.
Now the real rub. I have gotten the same thing working with Linux in 5 minutes following this post:
https://rtcamp.com/tutorials/linux/ubuntu-postfix-gmail-smtp/
Then within an hour my crontab and scripts were written, debugged, and blissfully sending email.
I would rather run this from my Mac server. I understand that this may become an in-depth discussion/debug session (remember the old sendmail.cf day?!) and would greatly appreciate someone's mentoring here.

Mail slow authenticating to Yosemite server

I'm running mail on a Yosemite server, and Mac Mail client on Yosemite. With the "Activity" window open on the Mail client, I see two copies of "Communicating with server: Authenticating" a lot. On the server /Library/Logs/Mail/mail-err.log is filled with lines:
Nov 06 10:58:06 auth: Error: od(simon,192.168.0.29,<MuZNkS4HfQDAqAAd>): Credentials could not be verified, username or password is invalid.

Nov 06 11:00:28 auth: Error: od(simon,192.168.0.29,<okUwmi4HhgDAqAAd>): authentication failed for user=simon, method=DIGEST-MD5
In the Server Mail settings, I have "Authenticate Using" set to "Local Users" (which checks the "Digest (CRAM-MD5)" and "Digest-MD5" boxes).
On the client, in the Mail IMAP settings for the account I have selected (picking what I think will be relevant) "Automatically detect and maintain account settings", "Port: 993", "Use SSL", "Authentication: Password" and "Use IDLE command if server supports it". I have NOT selected "Allow insecure authentication". I have previously selected "Authenticaion: MD5 Challenge-Response", but it seems to revert to "Password". I have an iPad and iPhone, both of which have "MD5 Challenge-Response" set, and don't appear to generate anything in mail-err.log
Mail from the Yosemite client works, it is just a bit sluggish. Under Mavericks new messages seemed to arrive simultaneously on all three clients, but now they hit iOS first.

OK, I think I have solved this. In the client Mail app I de-selected "Automatically detect and maintain account settings". Login then failed. Authentication had switched itself to "Password" while automatic detection of account settings was on. I changed authentication back to "MD5 Challenge-Response", and login now works, I don't get "Authenticating" hanging around in the activity window, and I don't get lots of "authentication failed" messages in the mail logs on the server.

Async tcp client and server. How can I determine that the client or the server is no longer available?

Hello. I would like to write async tcp client and server. I wrote this code but a have a problem, when I call the disconnect method on client or stop method on server. I can't identify that the client or the server is no longer connected.
I thought I will get an exception if the client or the server is not available but this is not happening.
private async void Process()
try

var data = await this.Receive();
this.NewMessage.SafeInvoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
How can I determine that the client or the server is no longer available?
Server
public class Server
private readonly Dictionary<IPEndPoint, TcpClient> clients = new Dictionary<IPEndPoint, TcpClient>();
private readonly List<CancellationTokenSource> cancellationTokens = new List<CancellationTokenSource>();
private TcpListener tcpListener;
private bool isStarted;
public event Action<string> NewMessage;
public async Task Start(int port)
this.tcpListener = TcpListener.Create(port);
this.tcpListener.Start();
this.isStarted = true;
while (this.isStarted)
var tcpClient = await this.tcpListener.AcceptTcpClientAsync();
var cts = new CancellationTokenSource();
this.cancellationTokens.Add(cts);
await Task.Factory.StartNew(() => this.Process(cts.Token, tcpClient), cts.Token, TaskCreationOptions.LongRunning, TaskScheduler.Default);
public void Stop()
this.isStarted = false;
foreach (var cancellationTokenSource in this.cancellationTokens)
cancellationTokenSource.Cancel();
foreach (var tcpClient in this.clients.Values)
tcpClient.GetStream().Close();
tcpClient.Close();
this.clients.Clear();
public async Task SendMessage(string message, IPEndPoint endPoint)
try
var tcpClient = this.clients[endPoint];
await this.Send(tcpClient.GetStream(), Encoding.ASCII.GetBytes(message));
catch (Exception exception)
private async Task Process(CancellationToken cancellationToken, TcpClient tcpClient)
try
var stream = tcpClient.GetStream();
this.clients.Add((IPEndPoint)tcpClient.Client.RemoteEndPoint, tcpClient);
while (!cancellationToken.IsCancellationRequested)
var data = await this.Receive(stream);
this.NewMessage.SafeInvoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
private async Task Send(NetworkStream stream, byte[] buf)
await stream.WriteAsync(BitConverter.GetBytes(buf.Length), 0, 4);
await stream.WriteAsync(buf, 0, buf.Length);
private async Task<byte[]> Receive(NetworkStream stream)
var lengthBytes = new byte[4];
await stream.ReadAsync(lengthBytes, 0, 4);
var length = BitConverter.ToInt32(lengthBytes, 0);
var buf = new byte[length];
await stream.ReadAsync(buf, 0, buf.Length);
return buf;
Client
public class Client
private TcpClient tcpClient;
private NetworkStream stream;
public event Action<string> NewMessage;
public async void Connect(string host, int port)
try
this.tcpClient = new TcpClient();
await this.tcpClient.ConnectAsync(host, port);
this.stream = this.tcpClient.GetStream();
this.Process();
catch (Exception exception)
public void Disconnect()
try
this.stream.Close();
this.tcpClient.Close();
catch (Exception exception)
public async void SendMessage(string message)
try
await this.Send(Encoding.ASCII.GetBytes(message));
catch (Exception exception)
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.SafeInvoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
private async Task Send(byte[] buf)
await this.stream.WriteAsync(BitConverter.GetBytes(buf.Length), 0, 4);
await this.stream.WriteAsync(buf, 0, buf.Length);
private async Task<byte[]> Receive()
var lengthBytes = new byte[4];
await this.stream.ReadAsync(lengthBytes, 0, 4);
var length = BitConverter.ToInt32(lengthBytes, 0);
var buf = new byte[length];
await this.stream.ReadAsync(buf, 0, buf.Length);
return buf;

Hi,
Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.
