[Seaside] Authenticaing Multiple Users

[Sven Van Caekenberghe]

In an attempt to authenticate multiple users for a Seaside app, I made 
a subclass of WAAuthenticatedSession and overwrote the method 
#authenticateUser:password: returning true or false based on our own 
test.

This didn't work at all, not when choosing that session class in 
/seaside/config, and not when using 
WAController>>registerAsApplication:sessionClass:

In both cases the effect was quite bizar: Seaside kept sending 
redirects until Safari gave up.

What am I doing wrong, or is there a better approach ?

Thx,

Sven
