OK I got transparent proxy working and I have Active Directory logging working (the Active directory documents need a little work I'll see if I can find time to update them. I have it working with centos 5.2 with setting the proxy in the web browser) However I was hoping that when I take the proxy option out of the web browser that it would still use the Active Directory login info. (I get the default access denied option) Is there a way to get it to use the automatic ntlm authentication info with a transparent proxy? or even a way for them to login? Or do I need to create a group policy and/or tell users how to setup a proxy in all the users computers for IE and firefox? It is no secret it just seems like a pain in the ass going around setting it up. And you all know how it is dealing with users.
