Squid Problem

Postby waqas373 » Fri Dec 10, 2004 12:47 pm

i m facing some problem in deploying Squid (on FC2) in Windows based network. actually i m migrating from MS-ISA 2000 and use Active Directory for user authentication. my squid.conf is attached and the problems are as follows

--MSN messenger is not working
--how can i make the same protocol rules in squid as in MS ISA means there is 4 type of protocol rules 1- only browsing 2- only Messenger 3- browsing+IM+POP+SMTP 4- all allow

i am confuse in the 2nd point above becz in MSISA i applied the security restriction on USER bases (Domain username added) actually i dont want to add machine's IPs

i think if i made four groups in AD then define the acl in squid.conf with limitred rights, is this approach wrong or not ???

thanks in Advance
