How to prevent concurrent user connection accessing squid proxy?

[Suhas!]

Hi all,

We have set up the squid server to use ntlm_auth to allow authenticated user (Win2k3 Domain Users) to access internet. Here the problem is if the username and password is shared ( especially on the non-domain member machine ), any user can access ineternet using that username.

Can we have setting done like, a single authenticated user can access internet from only one machine at a time, so that even if the same username is being used somewhere else, it would simply deny the second session for the same username.

Please help to configure "maximum concurrent connection by a single user" setting....

For this you have to find line authenticate_ip_ttl in your squid.conf

and set it as
authenticate_ip_ttl 1 seconds it will bind currently logged user to that machine IP.Then user cannot use same username and password on 2 or more machines.
