Can't add a user, exists. Can't delete does not exist.

[Dave Walker]

Ok I don't know how I got into this but something is broken.  A user was 
having account problems so I was going to just re-create the account.  I 
deleted the princ from Kerberos, and tried deluser the_username.  I got:

linux:/# deluser tsheller
Removing user `tsheller'...
userdel: error deleting password entry
userdel: error deleting shadow password entry
done.


So i try to adduser:

linux:/# adduser tsheller
adduser: The user `tsheller' already exists.

I looked through all: passwd, passwd-, shadow, shadow- for the username 
but none contain it.  Any ideas on how to make this work?
