samba - Apr 2009 - Question about multiples logins at the same time

Hi,

Do you have any guideline or variable in Samba in the configuration
file it determines that a user can not logging at the same time, in
order to avoid same login from different places at the same time.

For now, what I plan is to use a startup script that through me like a
flag indicating whether logged kick then through some mechanism.

I accept all suggestions.

Thank you

If you have  a ldap and samba domain there is a way to restrict the login to
a single workstation

A "root preexec" script tied to the netlogon share should do the
trick.
You may search for other smbd processes belonging to the same userid, and 
either return a nonzero value which will stop opening the netlogon share,
or use the info to kill the previous smbd - but that may have your user lose 
or corrupt open files.
Your support staff will not like either of that - often enough there are 
hanging smbd processes when a client suddenly crashed or the logoff event 
went unnoticed to the samba server due to whatever reasons, and your users 
won't be able to logon for a long time.
