Custom authentication and authorization on GAE?

Maybe taking a look at tipfy.ext. Auth ( doc wiki source code ) and tipfy.ext. Acl ( doc wiki source code ) would provide you with a little kickstart.

Those are extensions built on top of tipfy a open source lightweight python-based framework made for GAE.

From your question it is not clear if you are using java or python. I have done my custom user management with authentication/authorization using spring-security in java GAE. Things work fine.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
