The Samba-Bugzilla – Bug 13132
The KDC on an RWDC doesn't send error replies in some situations

Most of the KDC internal error get mapped to SDB_ERR_NOT_FOUND_HERE,
which is supposed to mean "pass this to an RWDC". That makes only sense
on an RODC. But it also happens on an RWDC and the high level sanity check
detects the bug and discards the response to the client.
