I am using mod_auth_radius2 with Apache version 2.0.54. When I attempt to authenticate, I see a successful attempt followed by 2 failed attempts, leaving me with a "401 Authorization Required" message in the browser. Any ideas? I have tried increasing the timeout. Here is the relevant portion of my httpd.conf: <IfModule mod_auth_radius-2.0.c> AddRadiusAuth <radius server 1>:1645 shared-secret 5:3 AddRadiusAuth <radius server 2>:1645 shared-secret 5:3 AuthRadiusBindAddress <server IP address> </IfModule> <Directory "/usr/local/apache2/htdocs/secure"> DirectoryIndex index.html AuthType Basic AuthName "secure" AuthAuthoritative off AuthRadiusAuthoritative on AuthRadiusCookieValid 15 AuthRadiusActive On require valid-user </Directory>
