Rob,

Thanks for your reply.

My predecessor had wrote code to pull user entries from the realm in
order to verify that:

1.)  A home directory is created (if not already) and apply the
correct ownership;
2.)  A work directory (Lustre) is created (if not already) and apply
the correct ownership.

Given what you've said, I'll perform a work-around within the code to
get a list of active users from a database table vs. the current
method.
