some more details follow ...

upgrade from 6.0-R to 6.2-R
everything went ok ..
i was doing changes in /etc based on my other computer settings
i was working via ssh(1), therefore i haven't noticed when logging on 
console stopped working.

what works:
log in via ssh(1) using public/private keys
log in on local console as root
su(1) to root

what doesn't work:
log in via ssh(1) using password
log in on local console as a normal user
su(1) to a normal user (it even doesn't ask for password a throws "sorry")

besides, as root i'm able to change passwords via passwd(1), but it 
doesn't help and a normal user cannot change their own password (old 
password check would fail).

i ran vipw(8) and it doesn't seem to me there's something wrong with my 

any hints pls ??
