Hello. I´v just gotten squid installed and working with NTLM and AD Groups. What i whant is to block some files for normal users, like .exe, .zip and so on but give admins the right to download them. I made two AD groups named "allowinet" and "admininet". If a normal user is trying to download an .exe he gets presented with a login dialog. I don´t whant that..i whant my "NOTE_FILETYPES_FILTERED" displayed to the user directly. If i cancel the login request i get the "Cache Access Denied" error message and if i enter my admin credentials i get to download it. This is what i put in squid.config: acl normalusers external nt_group allowinet acl adminusers external nt_group admininet acl blockedfiles urlpath_regex -i "/etc/squid/blockedfiles.acl" http_access deny blockedfiles normalusers http_access allow normalusers http_access allow adminusers deny_info NOTE_FILETYPES_FILTERED blockedfiles Thanks in andvanced /Patrik Hansson
