Cause: The group name is null, the group name is misspelled,
the invocation or given database is not the masterdef, or
one of the masters does not believe the invocation database
is the masterdef.

Action: If the given group name and masterdef were both
correct, connect to the masterdef and retry the request, or
relocate the masterdef at the (errant) databases using
relocate_masterdef.
