Hi, I posted a message a few days ago regarding a problem i had with ntlm_auth, since then i have done lots of surfing trying to find a solution and as yet have not found an answer. To get my users back online i have written a perl app returning OK or ERR and piped the username and password to ntlm_auth then grab the output and return OK or ERR. This is a bit of a work around however it now works perfectly the browser doesnt stall at all. The only real drawback is that authentication is no longer transparent. Ill keep searching for the ideal solution which would be the ntlm param I have a new question I have set an acl acl server src 192.168.0.10/255.255.255.255 and http http_access allow server Should this allow client 192.168.0.10 through the proxy without authentication? Client 192.168.0.10 still asks for username and password at the proxy, am i missing something. thanks Paul
