i'm going to close a MS ISA 2004 proxy server due to high license costs. Due to this business choice I have to find a valid substitute but freeware/GNU.
the aim is using this proxy as CACHE server for a big site (400 users). Only authenticated users can use the proxy. Windows 2003 Active Directory authentication based on AD group(s).
I have 10 years skills on most of the microsoft products but very poor in Linux/Unix OS.
I could use VMWare technology (ESX 3.5 vi3) with vitual appliance.
have you any suggestions how to approch this translaction? what about SQUID? i tried it 1 year ago but i had a lot of problems with AD authentications.
thanks in advance
