I have an Internet Security and acceleration server running at one of my sites what I would like to do is forward the request from that server to a squid server. However The IAS server uses Active directory for authentication and then squid server uses LDAP as it's authentication backend. When I try to forward the IAS server it just keeps asking for a username and password. How do I get the squid server to accept the credentials or at least just allow the IAS server through without asking for credentials.
