User authentication class

I found a User Management script called GenieGate (http://www.geniegate.com/).  I have also seen posts here that refer to patUser and Pear.  These projects come with their own tamplate engines.  I was hoping to user TBS as the only template system.

What are some ideas for a User Authentication system that integrates with TBS?  If there is not a good one, what have other TBS users done?  Code from scratch for each application?

Thanks,
Howard

Hi,

I don't know any specific Authentication System, but I've delveloped a small  authentication function for my own usage.
I think the authentication system should not impact on the Template Engine whatever it could be.
