Hello List, Sorry for the german mail before - I forgot this is an English list I am running Squid 2.4 with ldap_group_auth in a Windows active Directory Network. It works fine, Clients that are in the WWW_Users group can access the proxy, others can't. What we don't like is: Every user has to authenticate himself actively before accessing the proxy with login/password in a small authentication window. Can't Squid use the authentication data that windows provides? because the user is already logged in in the network, and even windoze sends login/password data, or doesn't it? Thanks! Markus -- Mit freundlichen Grüßen Markus Feilner May you always grok in fullness!
