I currently have Samba 3.028 and Squid 7:2.6Stable set up to authenticate Active Directory users to the proxy server. I want the proxy to be transparent though and it is not. While testing some ideas I found on the Internet, I tried the following command: wbinfo -a DOMAIN\\USERNAME%PASSWORD and received a "No user found" message. I then tried the following: wbinfo -a USERNAME%PASSWORD and received a successful authentication. Whenever an Internet browser attempts to go to a website, the user is prompted for a username and password. They cannot enter it in this format "DOMAIN\USERNAME" or they will receive a failure. Instead, they have to enter like "USERNAME". It occurs to me that the actual user that is logged into XP is "DOMAIN\USERNAME" rather than the other... is there a way to have Samba recognize this? I am wanting to get rid of the login required. Thank you in advance for your assistance. Shane
