We use AD for authentication via samba/winbind. I have ACL setup to deny downloading of file types but want to enable certain users to download. # Define files to block from downloading acl filedownloads urlpath_regex -i \.exe$ \.mp3$ \.mov$ \.mpg$ \.mp?$ \.avi$ \.rm$ # File Downloads http_access deny filedownloads I have a file located at /usr/local/squid/allowdownload that has three lines , each line is a username and the username exists in AD I tried doing something like the following but it did not work: acl allowdownload src "/usr/local/squid/allowdownload" http_access deny filedownloads !allowdownload Any thoughts?
