This is a very serious issue, and I have been pointed at
https://bugzilla.samba.org/show_bug.cgi?id=10398 in connection with
this. I agree we have no option but to delete these objects given how
little information remains.
However, we must ensure this does not happen again - these attributes
are mandatory, and if we get corrupt objects over DRS, I think we should
reject the replication.
