Hi, For a customer we have setup up a redhat directory server (rhds) that will hand out kerberos tickets which the user then uses to authenticate itself with squid. All works great, the users can go to internet sites without having to enter a username/password. But there's a second kerberos realm (windows, active directory) for which the ticket obviously doesn't work (yet .. we're working on that). We have configured a PAC so squid won't be used for intranet sites. Instead the Microsoft ISA server is used. Only every time the user browses the intranet, he's being prompted for a username/password by the ISA server. Now we already keep both usernames/passwords in sync between the RHDS and the AD. The only problem is that Microsoft ISA server requires a username in the form 'DOMAIN\username'. Now my question(s): is it possible to configure squid in such a way that it'll forward the username/password to the ISA server? If not, is possible to have squid already fill in the username field and have it prefix it like 'DOMAIN\username' ? Or is that a much better way to accomplish this? Obviously the best way would be to don't have the user be prompted for his credentials at all when browsing the intranet. Thanks in advance, Léon
