Wordpress Actions

I’m writing a simple plugin that will validate a user against some extra information when they login, but I can’t find the action that runs right after a successful login.

The WordPress Codex site leaves quite a bit to be desired.

Does anyone know which action I need?

Thanks so much. The term ‘authenticate’ never crossed my mind. I’m actually embarassed as I’ve been staring at that list for 2 days!

Sometimes you just need someone else to point out the obvious.

Thanks again.

Search for authenticate or login???
