[Samba] Counting the number of simultaneous logins

[Prakash Velayutham]

Hi,

How can we count the number of simultaneous logins for each user in 
Samba RELIABLY?
In my setup, I have several Windows domain clients each with a Citrix 
client installed in it. Windows clients are in a different subnet than 
the Citrix server. There is a Samba3 BDC in the subnet of the windows 
clients which they use to login to the domain. But when the user 
connects to Citrix for applications using the same domain 
authentication, login occurs at the Samba3 PDC. The situation is that 
the windows client has logged into the BDC, but the Citrix connection 
inside of the windows client has logged into the PDC. If I know how to 
count the number of simultaneous logins for each user, then using the 
patch given in http://www.utsc.utoronto.ca/~harper/samba/domain.html 
(Thanks Harper), I could run a shell script on the domain logon server 
during user's last logout to sync the different shares for that user.

Any suggestions please.

Thanks,
Prakash
