passwd

[Steve Phillips]

You have a corrupt shadow or passwd file.

One of your users is missing fields in either the passwd file or the 
shadow file.

Either delete all users and start again, or manually go through the file 
looking for extra or missing :'s

I have duplicated this error.

useradd testy
passwd testy
<enter password>
vi /etc/shadow
remove a field (including the : delimiter)
su - testy
passwd testy
enter old password
drop out with error
