None is passed if the option is set with --minlife=''. This is a valid
use case to delete a non-required attribute. In this case we simply
don't do the math on None and things work as expected.

Need to add a few more places where the DN will not be automatically
normalized. The krb5 server expects a very specific format and normalizing
causes it to not work.
Use a Class of Service template to do per-group password policy. The
design calls for non-overlapping groups but with cospriority we can
still make sense of things.
The password policy entries stored under the REALM are keyed only on
the group name because the MIT ldap plugin can't handle quotes in the
DN. It also can't handle spaces between elements in the DN.
