Well, my head is currently overloaded because I've followed so many how-to's and did so many things, but what I did is run the command net "ads join -U administrator" and the error I got was "Failed to join domain: Operations error". If I try wbinfo -u I get "Error looking up domain users" and yet if I try "kinit user" I get the prompt "Password for
user@domain.com" and entering the pass seems to go through.
Basically, what I'm trying to do is get our squid proxy server to return domain usernames when I tail the access.log or use SARG for reports instead of ip addresses. So I read somewhere that to do this you have to add the squid server to windows domain.
