[squid-users] Query on squid Windows 2k user authentication with IP address restriction

Hi

I,m using squid + windows 2000 + smb_auth for authenticating Windows domain
users. Now only user authentication is happening .Can I do both user as
well as IP
address authentication.
Scenario: User A having the IP address 10.10.10.1 can access proxy only
from his system and he cannot another system with different IP address.
I just need logic of the ACL to be given ,bcoz as the acl is getting
executed line by line my objective is not getting resolved.

squid.conf file is pasted below for reference .Squid version 2.4Stable7
,Redhat 8.0 , samba 3.0.
