Hi Guys, i've installed a Fedora Core 1 with samba 3 and squid 2.5 stable 3 (all with redhat rpms). Now i've joined our internal active directory and i see that "wbinfo -u", "wbinfo -g" and "wbinfo -a user%password" works great. ntlm_auth --helper-protocol=squid-2.5-basic works ok too but.. ntlm_auth --helper-protocol=squid-2.5-ntlmssp does respond only "BH"... what's the problem? Any ideas? Thanks Riccardo
