It is not possible with an out of the box Squid prior to 2.6, which isn't stable yet. There is a patch (connection pinning) that you require to do NTLM through a Squid. Best option would be to wait until the 2.6 branch is ready for production use. - Oliver Baumgärtel -----Original Message----- From: David Gullett [mailto:dgullett@xxxxxxxxxxxxxxxxx] Sent: Freitag, 23.

Each office has a squid server with the main office containing the parent cache. There are end users at all five offices. I can turn on NTLM auth at any of the branch offices and it will work until I turn on NTLM auth at the main office. Then the main office will work with NTLM but the users at the branch offices are being prompted for a username and password which will never authenticate. I also get errors like this in the squid logs at the branches: "Unexpected change of authentication scheme from 'ntlm' to 'Basic" Is it even possible to use NTLM authentication in this type of setup? Thanks, David Gullett Symmetrix Technologies
