Hi all, We are running squid 2.5 stable 5 on a redhat 9 (2.4 kernel) with ncsa_auth. Every so often our users complian that they are not able to authenticate through the proxy. We I check the usernname password, ncsa_auth says all is OK (but from the browser I get access denied. If I do a "squid -k reconfig", the usernames work fine (without recapturing or changing password). Below is a portion of the access.log file before I restart squid. 1142428454.928 20 146.141.x.x TCP_DENIED/407 1705 GET http://www.cnn.com/ user.name NONE/- text/html 1142428459.133 76 146.141.x.x TCP_DENIED/407 1738 GET http://www.cnn.com/favicon.ico user.name NONE/- text/html 1142428459.201 51 146.141.x.x TCP_DENIED/407 1738 GET http://www.cnn.com/favicon.ico user.name NONE/- text/html Many thanks Paolo Biancolli
