Hi all! I have successfully installed some new squid servers that are validating domain users via ntlm_auth. So nice! The problem i have now is that my proxy servers are in one domain but i have another small domain that also should use them. The smaller domain is not a member of the top domain and i am not allowed to set up a trust between them. Is it possible to do some thing like this... acl SMALLDOMAIN srcdomain SMALLDOMAIN.LOCAL http_access allow SMALLDOMAIN Users from the domain are connecting as SMALL\username. I would like to make a rule that allows them to use the proy servers. But i cant find out how to do it. I tested "acl DOMAIN1 src 192.168...", "acl DOMAIN2 src 172.16...", i could use that but the problem is that we are on the same network... Any help would be greately appriciated! Regards /Mattias
