Custom Authentication

Hello all.

I like to use Slide and I would like to be able to authenticate using 
some custom API that I write on the server side, namely I want the 
authentication happens on the server by calling into an api in a class 
that I provide. Is the right approach using JAAS or there is a simpler 
approach? Since I am not going to have a need for changing my 
authentication mechanism in future, I thought using JAAS would be an 
overkill and if there is a simpler "hook" that can be used to call out 
into my own custom api, then that would be better for me.

Does anyone have any suggestion?

Thanks,
Ali.
