Hi All I am running Squid as a transparent proxy and can't authenticate to sharepoint server. If I bypass squid then everything works fine. I have not compiled Squid with any of the authentication related configurables --enable-auth="basic,digest,ntlm,negotiate" --enable-basic-auth-helpers="LDAP,MSNT,NCSA,PAM,SMB,YP,getpwnam,multi-domain-NTLM,SASL" --enable-negotiate-auth-helpers="squid_kerb_auth" --enable-cache-digests --enable-ntlm-auth-helpers="SMB,fakeauth" --enable-external-acl-helpers="ip_user,ldap_group,unix_group,wbinfo_group". I see that sharepoint sends squid the following http headers in HTTP 401 response WWW-Authenticate: Negotiate\r\n WWW-Authenticate: NTLM\r\n But squid is not forwarding these headers to the client? If I bypass squid then everything works fine. Can someone please help here? Regards, Saurabh
