How To Configure Apache To Use Radius For Two-Factor Authentication On Ubuntu This document describes how to add WiKID two-factor authentication to Apache 2.x using mod_auth_radius on Ubuntu 8.1. A previous article described how to add two factor authentication to apache on Fedora. Interestingly, a patch has been created to update mod_auth_radius to work with Apache 2.2+, however, it has only been updated for Debian and Ubuntu. For Fedora and other RedHat flavors of Linux, it is recommended that you use mod_auth_xradius.

For one of my projects I have to set up two factor authentication. I have used Apache Free Radius module which acts as a client to Radius server. This setup is already been done and 2FA is working fine.
But, I'm facing an issue here. If user gets authenticated, it will stay authenticated (forever apparently) in both FF and IE browser, also if I supply invalid username or password, I get a "Authorization Required" response (that apparently stays forever too). But, In Chrome I didn't notice this behavior. Whenever I refresh the page, it apparently prompts for the username and password.
Can someone please suggest on this. Thanks in advance.
