Hello, Using squid 2.7 stable 9, I have set the debug_options to 29,2 which logs authenticated users, e.g: user 'xxx' has been seen at a new IP address (11.22.33.44) However, is there a way I can log unsuccessful authentication attempts? I have increased the debug level to 6, but it still doesn't log authentication failures. Is this possible in the squid 3.x series? Thanks, John. -- John Horne, University of Plymouth, UK Tel: +44 (0)1752 587287 Fax: +44 (0)1752 587001
