I'm not having problem with a password as such.  I can change it.  I 
just cannot log in using password as any user apart from root, whether 
logging locally (console) or remotely (ssh).  Users I tried su(1) are of 
course members of wheel group.  su(1) failed before even accepting any 
password.  There's something wrong somewhere and I need to find it, just 
don't know how.  Any ideas pls ??
