Oh I am such a fool.

Obviously, I missed the 'f-' off the at command line.

Sorry.

So we're gonna set their hard limits above current usage in LDAP, and they'll get seven days grace from when they next log in. However, that will leave the LDAP stored hard limits artificially high. So I want to drop an 'at' job in the queue, the first time a user logs in to the new server, that will reset the user's limits in LDAP to what they were.
