Hi I have got a Windows 2003 With SP1 domain controller and I'm moving my ISA Proxy to the Squid but I need to integrate the authentication. If I use the basic authentication it works but I need to integrate with AD. I have seen that after the SP1 on Windows it have been impossible to implemented. I not expert on Linux, could you help me to implement that solution? Sorry about my English I'm from Mozambique(not English native language). Thx Arafat M.
