[Typo3-dev] Login Question

[Marlies C]

We have the following 2 questions and could not find any answers. Could 
somebody enlighten us?

1. When you create a new login form in TYPO3 what happens in the submission 
of the form that lets the typo3 core know that login is happening? There 
seems to be no clear indicator of what the core is looking for when the 
login is submitted. I've looked through the tslib php files, with no luck. 
Can you help identify this.

2. When trying to pass variables to the login validator in the typo3 core, 
and are attempting to by pass the login box. What is the API call and what 
parameters are needed? We are trying to add an extra step to the login 
process before the login actually occurs.

Thanks,
