Thanx for your advice. But maybe i don't understand what do you mean. -If if i use the domain group membership, i must not use the win32_NTLM_auth? But if i don't use it, squid send me an error (if i prefix the line with "auth_param ntlm program" by a '#') what is the authentification helper i must use? Basic? with the external acl actually configured? 2005/8/24, Serassio Guido <guido.serassio@xxxxxxxxxxxxxxxxx>: > Hi, > > At 11.24 24/08/2005, guillaume.chardin@xxxxxxxxx wrote: > > >Hi, > >I experience a problem with squid NT installed on a winXP pro member > >of a win2000 Active directory domain. > > > >The proxy cache works perfectly ans authentication too.
