I've got a proposed fix for this in my drs-links-wip branch.  If you can
try that out, and let me know if it works, I would appreciate it. 

We don't have any good tests for this, so another task is, after the
'net vampire' tests are in the tree, to create a separate provision in
2000 functional level, and do an ldapcmp after replication. 

Once I know if I've fixed the issue, I'll tidy up the patches a bit
more, but any comments are of course welcome.
