While I can't help with the compile side of things, using SquidNT myself, I can lend a hand with the LDAP authentication within an AD environment. Using Squid 2.6 STABLE 14 we use the following lines (filed in the usual places): # Where InternetAccess is a group in Active Directory and GProxyUsers is a name we give the group for reference within squid.conf acl GProxyUsers external NT_global_group InternetAccess # Before http_access deny all http_access allow password GProxyUsers # If you're using NTLM you'll need something like the following auth_param ntlm program D:/squid2614/libexec/mswin_ntlm_auth.exe auth_param ntlm children 5 auth_param ntlm keep_alive on # If not you'll need to list your auth_param of choice Hope this helps :) Paul Cocker IT Systems Administrator IT Security Officer 01628 81(6647) TNT Post (Doordrop Media) Ltd. 1 Globeside Business Park Fieldhouse Lane Marlow Bucks SL7 1HY -----Original Message----- From: Mauricio Paulo de Sousa [mailto:mauriciopauli@xxxxxxxxx] Sent: 17 September 2007 15:14 To: squid-users@xxxxxxxxxxxxxxx Subject: Compiling Squid to auth on ldap server Hello all, I would like to compile my squid to make autentication on a ldap server, can anybody help me? if possible, show me how to define the acl autentication. thanks :D -- Mauricio Paulo de Sousa TNT Post is the trading name for TNT Post UK Ltd (company number: 04417047), TNT Post (Doordrop Media) Ltd (00613278), TNT Post Scotland Ltd (05695897),TNT Post North Ltd (05701709) and TNT Post South West Ltd (05983401).
