Hi all, I have just implemented squid with kerberos + ntlm + basic authentication. I have just been told accessing a sharepoint website on the internet has stopped working. It seems the site is running NTLM authentcation. I have wiresharked the traffic on the proxy and can see the request come in from the client then out to the web server and the NTLM fields are left in place. The sharepoint server is responding with a 401 unauthroized. Where would be the next place to start looking? I am running 3.1.10. Thanks all, Simon
