[squid-users] Ntlm auth problem continued

 
I've googled the hell out of this problem I'm having with a
debian(sarge) server and squid. I'm using Samba 3.0.2 squid 2.5stable9
with Winbind 3.0.14a. These are all stock .deb packages. I'm trying to
get NTLM authentication set up on my squid cache. It's working, but not
the way it should - IE clients aren't automatically logging in, and
passwords get sent in plaintext mode. Relevant configurations and debug
info below.. anything you could suggest that may help me would be
greatly appreciated.

sdproxy:/etc/samba# wbinfo -t
checking the trust secret via RPC calls succeeded
sdproxy:/etc/samba# wbinfo -a mydomain\\joe.tester%11QQaaZZ
plaintext password authentication succeeded
challenge/response password authentication succeeded
sdproxy:/etc/samba#

So it looks like samba is ready to handle ntlm auth, and so is squid.
Every time I open an IE window, I get prompted for a username and
password. If I enter a correct combination, I can browse. It is my
understanding that with ntlm this is not supposed to happen, that the
username/pass from my domain logon will automagically go to the server.
Running winbindd in debug mode I get the following log output:
[2005/08/26 15:46:04, 3]
nsswitch/winbindd_pam.c:winbindd_pam_auth_crap(477)
  [20149]: pam auth crap domain: SILPADA user: joe.tester
[2005/08/26 15:46:49, 3] nsswitch/winbindd_pam.c:winbindd_pam_auth(179)
  [20026]: pam auth joe.tester

 
If I fail the login, I get this output:
[2005/08/26 15:47:24, 3] nsswitch/winbindd_pam.c:winbindd_pam_auth(179)
  [20026]: pam auth joe.tester
[2005/08/26 15:47:24, 2] nsswitch/winbindd_pam.c:winbindd_pam_auth(361)
  Plain-text authentication for user joe.tester returned
NT_STATUS_WRONG_PASSWORD (PAM: 7)

I guess the plaintex authentication could be a last resort after an
attempt at challenge/response..
 
So, anyway, all I'm trying to do is get this auto-login working. Thanks
for any ideas you might pass my way.
