Hello, HTTP and FTP request using NTLM works fine with Mozilla and IE browser. Now i want to authenticate a client FTP (like Filezilla) with NTLM. I can't find a way to do this, is it possible ? Someone has ever done it ? I have tried to add these rules : acl intfullacl external NT_global_group intfull acl FTP_PORTS port 21 20 1025-65535 acl CONNECT method CONNECT It's work but for all users : http_access allow CONNECT FTP_PORTS This work for nobody : http_access allow intfullacl CONNECT FTP_PORTS Thanks for your answers. Aurélien.
