Hi, firstly, please execuse me if this has been discussed in the past however i am new to Squid and uncertain if this particular scenario is supported (even after reading forums) I have installed squid as a simple forward caching proxy (no cache_peer'ing or reverse proxy configuration). This is working fine for many websites on our intranet except for 2x websites that require clients to authentication via NTLM. Clients can access the NTLM sites and authenticate correctly if accessed directly. Clients cannot access the NTLM sites if accessed through the squid proxy. I have downloaded and installed the windows binaries (2.7 and 3.0) with default configuration. NTLM to the origin servers does not work with both versions. Is this a supported function by Squid? I have noticed (via wireshark) that the client is closing down the TCP connection and restarting post 401 message from Squid.
