*What is happening?*
At 10:00 PM maintenance will be performed on two of the LDAP servers to
ensure the stability of Authentication and Authorization of user accounts
to various resources provided by UMS and our contracted third parties.

*How long will it take?*
One system is user-facing and the other is not. For the user-facing system
the downtime is expected to be 10 minutes or less, and most things using it
will fail over to another member of the cluster. The back-end system that
requires attention should be resuming normal operation within half an hour.

*Why is this work necessary?*
If this work is not performed then (a) interactive user authentication may
become unreliable, and (b) regular changes to user accounts may not take
effect within a reasonable period of time.

*What happens if the work is not successful?*
In the case of the user-facing server most things using it should
transparently fail over to the other host providing the same service until
it is working again. If the back-end server does not resume normal account
maintenance processes on its own within a reasonable period of time then
staff will troubleshoot it and manually trigger any needed processes.
