Our ISA Server has only one single network adaptor installed. It works as a proxy server. Users who allowed to use the proxy server are grouped into a group and then grants the permission rights to that group.
The problem is that permitted users disclosed their accounts to others. I wondere if there is a way to limit single login (or single authentication) so that later logins with same account (same username/password) will be blocked.
Not where I'm aware of... However this should be dealt by the management. Sharing userIDs and passwords can be give you more problems then this.

Thanks for your opinion but I am just an ISA administrator. I cannot challenge our management. They just wonder if there is a way to limit users' concurrent logins.
