Hi everyone
I'm having some problems to setup squid 2.5.STABLE9 to autentificate users
in a windows 2000 server domain (active directory).
I have followed this guide: http://www.squid-cache.org/Doc/FAQ/FAQ-23.html#ss23.5
ntlm_auth is working fine on some client machines but not others.
I have tested it with windows 2000 professional, IExplorer 6+SP1 and
Firebird 1.02 and they don't work no matter the user logs in. However,
when in some machine works, any user that logs in that machine can use the
proxy.
I mean, it seems some client machine related problem, not specific user
problem. Neverthleless, there are no significat differences between the
clients as they are generated from the same norton ghost image (all
clients have the same software and versions)
With linux clients, the login/password dalog appears and auth works
perfectly.
when in the proxy machine, any winbindd related command works OK (wbinfo, nltm_auth...)
Now some specific stuff: Fedora Core 3 with 2.6.11-1.14_FC3 kernel

Some additional info & tests:
Winbindd privileged dir has the correct permissions: drwxr-x--- 2 root squid 4096 may 2 17:58 winbindd_privileged
# net join -S aulaserver -U Admin%ADMINPASSWORD [2005/05/02 19:10:03, 0] libads/kerberos.c:ads_kinit_password(146) kerberos_kinit_password Administrador@xxxxxxxxxx failed: Cannot find KDC for requested realm [2005/05/02 19:10:03, 0] utils/net_ads.c:ads_startup(186) ads_connect: Cannot find KDC for requested realm Joined domain AULADOM.
those are the only noticeable errors, however, it seems to join the domain
and autenticate users
# wbinfo -t checking the trust secret via RPC calls succeeded
#wbinfo -a USER%PWD plaintext password authentication succeeded challenge/response password authentication succeeded
wbinfo -u and wbinfo -g work also...
iin the access.log when ntlm_auth works the correct username of the client
appears, when not authenticated, NONE appears in the username field,
however, as you may see, sometimes an user receives a TCP_DENIED with NONE
as username and then the same request is a TCP_HIT authenticated: I dont
know if this is a normal beaviour or it can be related to the whole
problem.

Any additional help or guide will be very much appreciated, thank-you!
Any ideas or things to try?
I just tested the wbifo tests as squid user and it works perfectly....
thank-you
