Hi All, Before I get too involved in setting up a squid proxy, I'm wondering if the following scenario is possible. Step 1: User authenticates via Active Directory (ntlm_auth, I know this is possible) Step 2: Ldap object is updated with IP address of computer that user authenticated from (this is the uncertain bit). The reason for wanting #2 to occur is that there are other network devices active which handle access based upon ldap objects. Thanks, Matt Delves
