Hi people, I'm having some problem to implement NTLM at my squid box. I've followed the documentation guides but for some unknown reason isn't still working. Here is my squid.conf ( authentication portion only): auth_param negotiate program /squid-3.2.0.16/helpers/negotiate_auth/wrapper/negotiate_wrapper_auth -d --ntlm /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp --kerberos /usr/src/redhat/BUILD/squid-3.1.18/helpers/negotiate_auth/squid_kerb_auth/squid_kerb_auth -s HTTP/grazina2.redecamara.camara.gov.br auth_param negotiate children 30 startup=10 idle=10 auth_param negotiate keep_alive on As you can see I'm using the wrapper helper offered by squid-3.2, but my squid box is the squid-3.1. The Kerberos scheme works just fine. So how can I debug it? I really need NTLM too in order to authenticate users that access some old sites that don't handle kerberos. I really hope you guys can help me overtaking this issue. Regards, Wladner
