Hi, I have squid 3 with AD integrated, using squidGuard for filtering the traffic. When I try to access the sharepoint portal it give me error "401 - Unauthorized: Access is denied due to invalid credentials". Our sharepoint is also integrated with AD and without proxy it doesnt pop-up or require any credentials. We can access it directly How do I allow Sharepoint access for my users, is there any specific conifg that I need to add? My access log has this entry when trying to access sharepoint TCP_MISS/401 1640 GET http://spserver.domain.com:3000/Pages/Default12.aspx harry.potter DIRECT/192.168.10.64 text/html I changed the fqdn above. Regards
