Authentication provider for Cognos 8 on an XP professional os

[Cannondale23]

Is there a authentication provider I can configure with Cognos 8 running on an XP pro os. It's nice coming into the portal as anonymous user, but I would like to set up users in a 3rd party tool then configure authentication w Cognos 8
thanks

As you are using XP, you can set up a NTLM namespace to use local operating system users (leave NTLM domain name and PDC fields empty).
Then you can just add your users as local users to your XP.

Chapter "Configuring IBM Cognos 8 Components to Use an NTLM
Namespace" of C8 installation and configuration guide might be useful.
