[squid-users] Problem setting up squid with ntlm authentication

Hello,

I'm trying to setup a Squid Cache 2.5-STABLE4 with NTLM authentication
from an NT 4.0 Domain.

I use the wb_ntlmauth helper with the winbindd daemon that seems to be
correctly configured (wbinfo -r & wbinfo -g runs correctly).

When I try to authenticate from my Browser (IE 5.50.4807.2300 SP2) the
authentication is refused and a popup appear asking me login,
password&domain. If I try to enter them the popup appear again and
again....

I've verified my login&password with wbinfo : It's correct. So I think
there's something wrong in my squid configuration....

I have also tried with the ntlm_auth utility provide with samba 3.0 but
it's not better.

Can anyone help me please ?

The squid authentication is configured as follow :

auth_param ntlm program /usr/lib/squid/wb_ntlmauth -d
auth_param ntlm children 5
auth_param ntlm max_challenge_reuses 0
auth_param ntlm max_challenge_lifetime 2 minutes
...
acl all src 0.0.0.0/0.0.0.0
acl manager proto cache_object
acl localhost src 127.0.0.1/255.255.255.255
acl to_localhost dst 127.0.0.0/8
acl SSL_ports port 443
acl Safe_ports port 80 # http
acl CONNECT method CONNECT
acl domainusers proxy_auth REQUIRED
http_access allow domainusers
http_access deny all
