Using ACS as a web authentication server

[tahequivoice]

I have an ACS I use for Tacacs and Radius, and was wondering if I could use it to authenticate a web site for logins. I have an internal site that runs on Windows, but may move to Linux, and would like to have the techs use their Tacacs/Radius logins for the web site as well.

In Apache you can specify the authentication parameters in the virtual host configuration
