Sorry, I don´t wanna bother nobody, but since March I´m working on the pssibility to have squid for the security here at the company. After many problems we got squid working on the server but for sevral reasons, we had to abandone the mswin_check_ad_group cause no flexible for Universal groups. Now I moved everything thinking about the catalog of LDAP and there from commandline work all great!!!! But how is possible that in squid running this doesn´t work? For squid_ldap_group I thought was a problem of get the login in the right way, even if with -S I tried to strip the domain from the Ntlm authentication and so all the helpers were crashing. But now, after I tried from command line, I decided to make authentication only through squid_ldap_auth: sameresult, from command line perfect but from squid the browser continue to ask me again the authentication and then it fails! I don´t understand what is wrong! I don´t wanna throw away four months and the possibility to have a good security by Squid! Please, I tried all possible, anyone has an advice??? Thanks a lot Greetings Antonio
