No, sadly the configure check, exceptions and messages got a little
confused.  Please file a bug and we will fix it up, either to correctly
say it is required for the AD DC, or required for sefltest and the AD
DC.

For a number of reasons we do expect to be moving to LMDB, quite
possibly as the default, so expect this to get stronger in future major
versions.
