I didn't had a deep look at your patch but it's very good that someone 
started to tackle this subject !

Did your patch take care to periodically check if the ISTG attribute has 
been updated, to update it if the DC is the ISTG and to try to promote 
as ISTG if the previous one.
I noticed lately that when dealing with more than 1 site and with mixed 
(Samba and Microsoft) DCs it's important to correctly manage this attribute.

Good, if I'm not misunderstanding it's the KCC tasks to periodically 
send DsAddRef in order that other DC add or update their repsTo is it in 
your patchset ?
