Re: [squid-users] running old wbinfo, pam_winbind or libnss_winbind clients

Look at the Samba 3.x sections for the FAQ again. Your using the
squid-provided winbind helpers which are ONLY for later Samba 2.x
versions.

You need to be using the Samba provided ntlm_auth helper for 3.x.

Subject: [squid-users] running old wbinfo, pam_winbind or libnss_winbind
clients

I've just installed the Squid 2.5.STABLE7 & Samba 3.0.7 on my FreeBSD
box.

I am trying to authenticate it to the Active Directory (for my Squid
server).

When I go to a webpage using the squid server, I get this error from
Winbind:

Repeated over and over and over again in my log.winbind or
/var/log/messages file.

I also get this too:
Oct 26 09:25:28 eclipse (squid): authenticateNTLMHandleReply: called

Oct 26 09:25:29 eclipse kernel: pid 61947 (squid), uid 100: exited on

I can authenticate using the test commands from the website:
# ntlm_auth --helper-protocol=squid-2.5-basic
mydomain+myuser mypasswd
OK

# wbinfo -t
checking the trust secret via RPC calls succeeded

This is all on a brand new install of Samba & Squid.

 squid -v

Any clues?

Thanks.
