Hi Henrik, Since our last conversation we have spent some time learning a bit more about how the squid_ldap_group authentication works. Now realize that the ldap group membership test does strip the domain as you said it does. My problem appears to be with the squid_ldap_auth as it does not appear to be able to strip the domain and I am trying to use both auth and group features together. I am still unsure as to whether I am using these modules in the correct way, if I am then I would need the auth module to strip the domain as well. I would appreciate any comments you would have about the way I am trying to do things. Thanks, Clayton York Barone, Budge & Dominick 011-5328577 -----Original Message----- From: Clayton York Sent: Thursday, July 16, 2009 10:26 AM To: 'Henrik Nordstrom' Cc: Squid Users Subject: RE: Help Please : NT Domain name stripping in squid_ldap_group Hi Henrik, We are running squid-2.6.STABLE21-3.el5.

Which Squid version is your squid_ldap_group from? Note: access.log always shows the full username. The removal of the domain part is done by squid_ldap_group when checking the group membership only.
