Remember me does not work on trunk

[Harald Wellmann]

I cannot get the Remember Me feature to work on trunk. The only cookie 
my browser receives when I log in with "Remember Me" turned on has key 
"username".

I'm not a Spring expert and I'm afraid I do not really understand what's 
going on here, but I would have expected a second cookie.

Any hints on solving this, e.g. enabling particular loggers to find out 
what's going wrong...?

Thanks,
Harald
