For various reasons, we've had to disable accounts. Some for weak passwords,
some for security vulnerabilities, or myriad other reasons. If an account
is sorried, once you've made sure the original problem
has been resolved (you can check User_Info via check)
you can unsorry their account and let them log in again.
unsorry will remove the user from the sorry group, re-enable a login shell,
and generally allow them to use their account again. Occasionally more
than simply unsorry may be necessary depending on changes in the
infrastructure.
unsorry should be run on supernova.
$ sudo unsorry username
It may also be necessary to run nscd -i passwd on tsunami.
Make sure to document all sorrying and unsorrying using note
