Hi all!

I feel this is a stupid problem (so I'm not going to spam current-users@ with 
it ;), but I can't find its root.
I'm using -current (3.99.7) on a sparc64 system and as root I added a user 
with

groupadd user
useradd -G wheel -g user [some other options] user

Now, when I login as  user  and type "su", after inserting the right password 
I get

su: Sorry: authentication error

I think I've missed something but I can't understand what... 
Please be patient to me :) and thanks

david
