Authentication via Kerberos

["Bryan Richardson" <btricha@xxxxxxxxx>]

Hello,

I'm not new to Apache, but I am new to trying to set up authentication other than the basic type.  I've been tasked to set up a Trac site for software projects within my organization at work, and I'm required to restrict access on a need-to-know basis.  Our company uses Active Directory (of course), and I'm wanting to set up my web server such that users of the Trac sites can use their Kerberos password rather than using a different one stored locally on the web server.  I'd like to still be able to specify what users are allowed access, but once I've granted access to a specific username (one that's in the Active Directory) I'd like the Kerberos password associated with the username to be the password used by Apache.

Is this possible?  I assume using Kerberos is possible, but is it possible to specify users allowed rather than allowing all users in the Active Directory access?

Thanks in advance! -- BTR
