[TYPO3] External FE Auth

I recently ran into the same problem (with BE users, but the system is 
the same). Here is what happens (I'm forgetting some steps, such as when 
authUser() is called, but it's the basic idea):

- the user data is retrieved (getUser() method of the auth service)
- the returned array must contain a user uid
- a session is created with that uid
- the returned array is emptied
- the array is filled again by reading the session entry and joining it 
with the users table (fe_users or be_users)

I suppose this is for increased security.

The result is that you absolutely need to have a uid for each user. I 
suppose you could imagine creating temporary records with dummy uid's in 
the users table, but then you would need to come up with some clean up 
mechanism.
