Virtual users

I've only just recently migrated to OSX server since the release of snow leopard. Ive come from a debain server.
I used to be able to have a virtual user table under sendmail allowing me to have multiple domains with similar usernames in each domain thus:-
[email protected] domain1username
[email protected] domain2username
It seems under workgroup manager (is this the place to add these?) under shortnames even if i create a shortname for domain1username that is [email protected] and a shortname for domain2username that is [email protected] the mail server wont allow mails for [email protected], bouncing with the error message <[email protected]>: User unknown in virtual alias table
Can anyone shed any light or point me to a manual/fix?
Thanks muchly!
Andy

Here's what I've found that works.
In WGM in addition to the shortname you need to add the email address. In this case your username for domain1 and domain2 are the same.

LoadRunner SAPGUI Virtual Users Decline

I am trying to perform a Load Test on SAP R/3 using LoadRunner 9.5. I have 120 virtual users that I would like to run for an hour. I have distributed these 120 vusers over 6 scenarios on 5 load generators. The maximum number of virtual users that I have been able to run at one time is 114. The number then slowly declines over the next 40 minutes and stabilizes at 91 vusers (which run for the remaining hour). The messages I get from LoadRunner indicate that users have logged on and navigated to their assigned transaction code in SAP, but fail to perform the first step in that transaction code (this happens for ME21N, ME22N, ME23, FB10, F-43 which is all of the transaction codes that I am testing). I have worked with the Basis Group here to ensure that there are enough interactive dialog work processes, set each scenarios think time to random, initialize and start each vuser individually, and ensured that each load generator has enough RAM. The only thing left that I know to try is to increase the number of dialog processes per user. However, we cannot figure out the parameter name to do this. If anyone knows the name of this parameter or have any other suggestions, please let me know. Thanks!

Hello Andy,
We are having a similar problem, did you ever get an answer about this issue?
Thank you!

Pure-ftpd - different permissions for virtual users?

I seem not to be able to find out how I could declare different permissions for different virtual users. In /etc/pure-ftpd.conf exists one line to declare permissions using
#umask file:folder
umask 133:133
umask matches the numbers to 'UserGroupOthers'.
Now that virtual ftp users belong to a real existing unix user / group, I wonder who is Users, Group and Others?
Users = virtual ftp user ?
Group = virtual ftp group ?
Others = anonymous visitors?
How can I tune it, so one virtual user can add files - f.e. to be used by a scan station - while others shall only read, having anonymous disabled?
This gives me a headache.

Ok, let me think. What did I do?
I had different users. User X, Y and Z.
Then, I had a shared directory above their home directories.
While in the system, (not in pure-ftpd) I symlinked.
(Note that doing something in user X's directory, like ln -s ../shared didn't work---I had to do ln -s /usr/home/ftpuser/shared).
Then, I ~think I played with the permissions on shared and got what I wanted.
Then, after a few hours on this, they changed their minds about what they wanted, everyone was allowed to use shared, but different companies had to have their own directories, so I no longer have that config.
For what it's worth, you can take a quick look at my page
http://www.scottro.net/qnd/qnd-pureftpd.html
but I don't think it covers that situation.
HTH, though I doubt that it did.

Vacation responses for SA-style virtual users

We've chosen to implement virtual users via Server Admin, rather thsn by manually editing files. We're now looking for a way to implement vacation responses. According to the 10.4 mail documentation, Sieve won't work with virtual users implemented this way. What are the alternatives to Sieve, specifically for vacation responses? Thanks to whomever can help.

I am sorry to disappoint you, but there is no easy
way of doing this. You'd be better off implementing
postfix style virtual aliases.
I was afraid you'd say that but thanks for the reply.

[Solved] Pure-ftpd only virtual users

Dear arch-users
I'm using pureftpd from extra. I've created a lot of virtual users for my LAN, everything is working fine.
But it is possible for system users to log on an see their whole /home/users directory, with their user/pass combo. I've disabled it, by setting the minUID to a very high number, but I think their is a more decent solution for this problem.
So what is the best solution to only allow virtual-users to log on?

Solved the case
# If you want to enable PAM authentication, uncomment the following line

UnixAuthentication no

Rejecting emails to unknown virtual users before filtering them?

hi
it appears that all emails to any virtual domain on my server gets "filtered" BEFORE it gets checked against valid users for that domain.
1. mail in
2. filtered
3. checked if valid
4. rejected (unknown)
Is there any way to have the validity check done before the filtering?
It would seem more economical if it worked like this...
1. mail in
2. checked if valid
3. rejected (unknown)

I have used pterobyte's virtual mail set up in the past without a problem - and found that Apple has broken the postfix in 10.5 (as it says on the PDF that pterobyte is recommending.)
If you, like me, had already set up each user in WGM to have two shortnames (the second one - an email at virtual domain) then you only need to append the users to your "virtual" file in "/etc/postfix".
EG:
[email protected] shortname
do this for each virtual user, postmap the file and reload postfix. Then the mail server will accept the email addressed to your virtual user.
By All Means: read the PDF for more instructions.

Chroot SFTP for virtual users

Anyone tried this on Arch?
http://www.minstrel.org.uk/papers/sftp/
Basically allowing chrooted virtual users SFTP access (no users/shell access). I thought of switching completely to SFTP from FTP/SSL, but don't want to add a user for each virtual host.
Last edited by phrozen (2013-08-24 15:54:51)

To allow virtual user on the site, you need add a SAML authenticator provider to the security realm. From the log, I don’t see there is a SAML authenticator configured. This SAML authentication provider is used by SAMLIA to authenticate (in fact, it simply returns an authenticated identity) the virtual users.
You should also pay attention to the control flags of the newly added SAML authenticator and your existing DefaultAtn provider. For example, the control flags can be set like this:
SAML Authenticator - SUFFICIENT
DefaultAtn - SUFFICIENT
If DefaultAtn’s control flag is set to REQUIRED, “Virtual Users” will not work, too.

[SOLVED] vsFTP and virtual users

Then I point my browser to ftp://myip and I get a prompt for username and password, but the problem is that the user I created (ftpguest) can't log in. What am I missing?
Thanks

Vsftpd and virtual users - SOLVED!

I have followed the wiki to build my vsftpd server, which works fine with local users
However, I wanted to build the server with virtual users, and I have made everything as described in the wiki,
but it doesn't work - I got a 530 error - Login incorrect.
I think it should be a problem with the password database file, but how to solve it?
here's my vsftpd.conf:
CODE:
listen=YES
anonymous_enable=NO
local_enable=YES
write_enable=YES
dirmessage_enable=YES
xferlog_enable=YES
connect_from_port_20=YES
xferlog_file=/var/log/vsftpd.log
#ftpd_banner=Welcome to blah FTP service.
chroot_local_user=YES
pam_service_name=ftp
guest_enable=YES
guest_username=virtual
virtual_use_local_privs=YES

I don't think so :

ls -l /srv/
drwxr-xr-x 2 virtual virtual 4096 máj 6 22.20 ftp

[solved] VSFTPD + Virtual Users + different home directories

Hi All,
I've been trying to get VSFTPD setup to allow ftp access to some of my clients to access their web files. I've got VSFTPD up and running via the Wiki, but my virtual users can't log in. The only thing that I didn't do from the wiki was the "useradd virtual" as I didn't think it was needed. Also, the wiki only covers one directory for all users, I want to have each user to have access to their own web directory and nothing else. I think I may just have something a little off in my vsftpd file. Thanks!
vsftpd.conf
anonymous_enable=NO
local_enable=YES
write_enable=YES

xferlog_enable=YES
connect_from_port_20=YES

Hi GravityGripp,
as posted at the beginning of the thread in /etc/vsftpd.conf the 'pam_service_name' option is 'vsftpd' but here you are referencing /etc/pam.d/ftp as PAM service name but in vsftpd.conf you told to use 'vsftpd' as PAM service for auth.
About your need to define different directory for each ftp virtual user in my installation I allow ftp access to virtual users (defined in MySQL and auth via pam_mysql); to let users have access to their own ftp directory (with different auth read only / read-write) I used the user_config_dir option (see man vsftpd.conf).
Here an extract of my '/etc/vsftpd.conf':
# This powerful option allows the override of any config option specified
# in the manual page, on a per-user basis. Usage is simple, and is best
# illustrated with an example. If you set user_config_dir to be /etc/vsftpd_user_conf
# and then log on as the user "chris", then vsftpd will apply the settings
# in the file /etc/vsftpd_user_conf/chris for the duration of the session.
# Default: (none)
user_config_dir=/etc/vsftpd/vsftpd-user-conf
Each time I add a new ftp virtual user that need a personal ftp directory, under the dir '/etc/vsftpd/vsftpd-user-conf' I create a file named as the username where I define the personal ftp directory and the auth on it (RO or RW).
Example for user 'test' (file '/etc/vsftpd/vsftpd-user-conf/test'):
# vsftpd per-user basis config file (override of any config option specified
# in the vsftpd server config file)
# TEMPLATE
# User test - Description for user test
# Set local root
local_root=/srv/vsftpd/test
# Disable any form of FTP write command.
# Allowed values: YES/NO
write_enable=YES
Of course the dir must exist and have the right permissions to allow the user to connect.
Hope that this will be of help.
bye

Ramp Down Virtual Users Feature in OLT 9.1

Hi,
I would like to know is there any ramp-down feature available in Oracle Load test tool similar to one available in HP LoadRunner?
I was able to find only ramp-up field entries in auto-pilot tab.
Please do let me know more info regarding it
Regards,
Mahesh

Hi,
The Scenario pattern which you had mentioned is for ramping-up users which usually occurs during start of test execution which is readily available in autopilot tab. I mean ramping-down users which occurs at the end of test execution for defined period / goal.
At present, users are made to exit once they complete current iteration.
Is there any method available for graduall exit of virtual users?
Hope you understood my query.
Regards,
Mahesh

Migrating Virtual Users

OK, I have a feeling I can do this, but I'm having a bit of difficulty, so I thought I'd ask to see if it was just plain a silly thing to do
Is it possible to make a user that can do nothing else besides receive/send email? i.e. I have a virtual domain "virtual.com" and I would like to create [email protected] and let joe receive email but do absolutely nothing else.
That seems fairly straightforward and I think the policy stuff I can do in workgroup manager will get it done (once I figure it all out
The second part, though, is harder:
Can I create a user who owns "@virtual.com" and can administer it (create the users described above who have no other access than email) so that they don't have to bug me every time they need to tweak someone's email?
In the past, I had postfix and courier imap (rather than cyrus) reading from a MySQL database which contained these "virtual" users. Substituting LDAP for MySQL and cyrus for courier should be able to do this, but I'm trying to figure out how users can administer the LDAP part of it securely...
Thanks for any advice you can offer!

There really was no solution to this.
Sure, if you want to do a lot of OpenLDAP work you could simulate it, but I decided to just make "real" users instead.

Where is virtual user data stored?

I'm moving ahead on my mirrored servers endeavor but need to know where OSX stores virtual user (for mail service) data so I can sync it.
Anyone know?

Assuming default locations, all mailboxes are stored in:
/var/spool/imap/dovecot/mail

Sendmail virtual user table

Hi,
Can we setting up virtual user table in ironport?
Thanks.
Alex Ling

Hi Alex,
You might want to check the integrated user guide in the IronPort for the command 'aliasconfig'.
Depending on your specific needs, the alias table may fit the bill.
