Server 2012 NPS Server not authenticating IKEv2 requests

Hello Experts,I am having a weird problem regarding NPS Server when I upgraded my vpn servers from server 2008 R2 to Server 2012 R2. Actually in my infrasturcture I have a Windows 2008 R2 based AD and in its domain I have an NPS server joined as member server. This NPS server is based on server 2012 R2, when I upgraded my VPN servers from server 2008 R2 to server 2012 R2 the IKEv2 stops working every other protocols works on windows 7 when I try to connect using IKEv2 it hangs at verifying username and password nad when I tested IKEv2 in Win 8 it says IKE authentication credentials are unacceptable, inspite that my server certificate is valid EKU compatible. When I connected IKEv2 via my other server whose server 2008 R2 based VPN Server The IKEv2 works like a charm without any issues successfully authenticating. The problem seems to...

Indeed the 255.255.255.255 subnet mask is expected for non-compliant clients.
But my issue is that non-compliant clients get an IP address from the entire subnet and i want to assign only a specific
range in my entire subnet/scope to be assigned to non-compliant clients.
It's funny you can specify an IP Address Range in the DHCP policy but then it doesnt work.
On the other hand you have a valid point there Greg about DNS/DHCP flooding.
Still hope to hear why this setup will not work and if it is supported or can work tough :-)

Connection to licence server not authenticated

Hello,
I have made a backup of a SBO database in SQL Server 2000 and restored this over an existing database in SQL Server 2005. Made a backup of this one and then opened SBO and updated the administration.
Unfortunately I get the system message (after entering username and password) once updated: Connection to licence server not authenticated
The administration from the client is in SBO2005A SP01 PL41 and mine is SBO2007A.
How can I get around this. The other administrations I can access..
Regards,
Petronella

What do you mean by
The administration from the client is in SBO2005A SP01 PL41 and mine is SBO2007A.*
You could not use a 2005 client on a 2007 Server

Brand new Open Directory server not authenticating 10.9, 3.3.2

I'm hoping somebody here has ran into this as it's driving me up a wall.
I'm on a completely clean install of OS X Mavericks, with the installation from the App Store.
On top of that, a completely clean install of Server.app 3.2.2 is installed.
This server has a FQDN, and when I check to see if the hostname resolves in DNS, it totally does. DNS is not turned on as a service, but DNS server settings are correct and the server can hit the outside internet just fine.
So my steps are as follows: Install Mavericks, clean onto a new partition. Update with all patches. Set Static IP. Install Server 3.2.2 which installs without error. Check hostname settings. All good there. Verify permissions. Create OD Master. I cannot get a single newly created with Server.app Local Network user to log in, even with home folders all 100% local to the client machine. I've unbound and rebound the client machine. I've restarted everything. Nothing.
When attempting to log in, if I set it to reset password at next login, the prompt to reset the password will appear. I know at least initial auth is taking place, or I wouldn't be getting a password reset screen. After attempting to reset the password, neither the original temporary nor reset password will work. Users cannot log in.
Here are the errors generated, with my info edited out:
Jan 14 17:49:35 server slapd[111]: passwd_extop: (null) changed password for uid=test,cn=users,dc=controller,dc=domain,dc=edu

Jan 14 17:49:41 server slapd[111]: conn=1197 op=3: attribute "entryCSN" index delete failure
I understand this is common for users upgrading from 10.6.8 but this is completely clean. I'm not usually administering an OS X server; I'm completely lost.
Have tried: Recreating master, rekerberizing
Using scutil and host to verify the DNS on the server works perfectly. Am I missing something small with DNS? We are a fairly large org with DNS not being provided by this server. If you think a different log file would help, please let me know which one.

What do you get from this:
sudo /usr/libexec/slapd -Tt
Anything in /Library/Logs/slapconfig.log?
Also, have you tried the suggestion here:
Open Directory - Local Network User/Group - GONE

Managed Server not accepting HTTP requests

We restarted our managed server (it had Oracle Identity Analytics deployed) and received an error after the application came up (pasted below). The application seems to be running but when I attempt to access it I'm getting a Page Not Found error. I deleted the OIA deployment altogether and just started the Managed Server and, though it is Running, I'm seeing the same error and still getting Page Not Found.
I also restarted the AdminServer and now I'm seeing the same symptoms there. At this point the environment is completely inaccessible. Any ideas on what may be wrong or what the solution may be?

BT SMTP server not authenticating

Hi all,
I have tried all avenues I can think of, including looking all over these forums and trying everything people have suggested but with no luck.
Since yesterday afternoon an email account has stopped sending emails (receiving is fine), no settings were changed. I keep on getting prompted for user name and password for the mail.btinternet.com mail server. I get this problem in both outlook and outlook express (for testing) and also I cannot send emails via the ipad either. I have tried speaking to the BT support but they didn’t offer any help as we are using mail clients and not their web mail.
SMTP settings are: Port = 25 none SSL, Authenticate using same as POP3 log on
I have tried port 465 with ssl and 587, the lot.
I have notcied this does work on 1 other computer I have been testing on, just to add to the confusion!! Any help or suggestions would be great!
Thanks in advance
jezza
Solved!
Go to Solution.

My problem is now resolved. In the end i restarted the router. The only thing I can assume is there is a stuck session on BTs STMP servers after restarting the router I got a new public IP.
BT support was as usual, a waste of time and no help what so ever. Clearly a problem on their side but out right refused to help.
Im not sure this will help your problem if you cannot send via BT webmail, this was never a problem for me.

If you are able to authenticate via TACACS I would believe that this indicates that there is not a problem with your configuration of the TACACS server(s) (addresses are correct, keys are correct, etc) and that the TACACS server recognizes the router ok.
So I assume that either there is some problem on the router generating the accounting records. Or that there might be a problem on the server and receiving and processing the accounting records.
As a next step in investigating this issue I suggest that you run two debugs on the router:
debug aaa accounting
debug tacacs accounting
While the debug is running have someone access the router and login, access privilege mode, and execute several commands. Then post any debug output.

The MySQL client that the error refers to isn't the version
of MySQL,
but the MySQL library bundled with PHP. It sounds as though
your hosting
company has upgraded to MySQL 4.1 or higher, but is still
using PHP 4.
> I'm not sure how to edit the connection string to make

You can't. It's the way that the user account passwords are
stored in
MySQL. You need to get the hosting company to upgrade to PHP
5 or to
reset the passwords in MySQL using the OLD_PASSWORD()
function. This
needs to be done by someone with top-level administrative
privileges on
the database.

SharePoint designer 2013 crashes most of the time, when opening sites. Error: The server could not complete the request.

Hi,
I have few sharepoint 2013 site's, which I am trying to open in sharepoint designer 2013.
After adding the site name in open site and clicking ok, the sharepoint designer crashes. At times the sites open, but 90% of the time, the sharepoint 2013 designer has crashed. I get the message "The server could not complete the request. For
more specific information, click on the Details button".
When clicking on "Details" button, there is a empty box. The error message never gets closed and have to kill the process.
I have tried doing "IISreset" multiple times, which has not helped.
Has anybody faced this issue? How to fix this?
Thanks

Hi Venkatzeus,
Firstly, I need to verify the followings:
1.Whether this issue occurred on a specify SharePoint 2013 site.
2.Whether you have extended the problematic site.
Make sure that your user is a site administrator. If you have extended the problematic site, please add it to AAM.
There are other probable causes for this issue:
1.Anonymous authentication is not configured for the problematic web application in IIS
Fix: Enable Anonymous authentication in IIS
2.Server is running out of memory
Fix: Free up memory on the server

10.6.8 Server - workgroup manager not authenticated

I have 10.6.8 Server that has suddenly stopped accepting the dradmin password when using Workgroup Manager. Workgroup Manager connects, but in not authenticated mode. When I click the lock icon and am prompted for the ID & Password it is rejected. I know with 100% certainty I am using the correct administrator ID and password. I am running Workgroup Manager directly on the server computer. I'm able to log on to the computer as the local administrator. Server Admin works fine with no authentication issues.
I have not applied the 10.6.8 Supplemental update, but wonder if that might be helpful.
It is very concerning to be locked out of my own server. Any suggestions why this is happening and how to reslove it?
Thank you,
-Joe

The logs revealed that dradmin was actually authenticating successfully, but for some reason Workgroup Manager was still in unauthenticated mode. I installed 10.6.8 Supplemental update and found no improvement.
All users have portable home directories and everything with Open Directory was functioning properly. DNS and Kerberos were confirmed to be working properly. Several restarts and shutdown/startups were performed and I never was able to get Workgroup Manager to authenticate. So after a few hours troubleshooting last weekend I decided to restore the server to a disk image that was created 20 days earlier. I elected to do this this because I needed to get it resolved on the weekend to minimize the chance of downtime during business hours. The only thing on the boot drive is the server OS an everything else is stored on an external RAID so it was fairly simple for me to restore then get everything current again.
I kept an image of the server with the problem so I can restore it to a standby server to experiment with any possible fixes that I may come across in the future. As of now I don't know why it happened nor how to fix it without restoring.

Catch(Exception exception)
Given Below is the Error.. The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.
Solution:
The error might occur due to following cases.
case 1: when the password is wrong
case 2: when you try to login from some App
case 3: when you try to login from the domain other than your time zone/domain/computer (This
is the case in most of scenarios when sending mail from code)
There is a solution for each
solution for case 1: Enter the correct password.
Recomended: solution for case 2: go to
security settings at the following link https://www.google.com/settings/security/lesssecureapps and
enable less secure apps . So that you will be able to login from all apps.
solution 1 for case 3: (This might be helpful) you need to review the activity. but reviewing the activity will not be helpful due to latest security
standards the link will not be useful. So try the below case.
solution 2 for case 3: If you have hosted your code somewhere on production server and if you have access to the production server, than take remote
desktop connection to the production server and try to login once from the browser of the production server. This will add exception for login to google and you will be allowed to login from code.
But what if you don't have access to the production server. try
the solution 3
solution 3 for case 3: You have to enable
login from other timezone / ip for your google account.
to do this follow the link https://g.co/allowaccess and
allow access by clicking the continue button.
And that's it. Here you go. Now you will be able to login from any of the computer and by any means of app to your google account.

Remote Server returned '530 5.7.1 Client was not authenticated'

Hello,
I migrating from Exchange 2007 to Exchange 2013.
The Exchange 2007 infrastructure look like:
-2 CAS ( Hub1 and Hub2)
-2 MBX ( mbx1 and mbx2)
We add Exchange 2013 in the mix
2 CAS ( CAS-2K13-1 and CAS-2K13-2)
2 MBX ( MBX-2K13-1 and MBX-2K13-2)
All mailbox are curently on Exchange 2007. All inbound email pass by a SMTP Relay who forward the email to a NLB of Exchange 2013.
The send connector (internet) forward email to the SMTP relay, and the source server are only 2K7 server.
My problems is : if I replace the two 2K7 server from the source server for the 2K13 MBX, I receive this message:
The following organization refuse your message: MBX-2K13-1.contoso.com
Generation server : MBX-2K13-2.contoso.com
[email protected]
MBX-2K13-1.contoso.com
Remote Server returned '530 5.7.1 Client was not authenticated'
idea?

Do you smarthost from the send connector to another SMTP gateway?
