As far as we are aware, this can only break if you ran a pre-release
version of Samba 4.1 against your server, and joining Windows 2008R2
will likewise break. 

Is this the case?  Can you test a trial copy of Windows 2008R2 to
confirm?  If we differ from Windows in implementing this check then we
can re-consider, but currently we are trying very hard not to further
propagate a corrupted domain.  

All that said, if you had for a time joined Samba 4.1 pre-releases (ie
git master around June to September this year) then clearly we need to
find a way to resolve this corruption for you.  We have such tools for
Samba DCs once replicated, but our anti-corruption test is preventing
you getting into a state where we could run it!
