[Samba] old dc still mentioned as msSFU30MasterServerName

[mourik jan heupink - merit]

Hi,

Our DC1 had to be taken offline due to corruption. Roles were seized, 
and I managed to get rid of the directory metadata by using this script 
from microsoft:

http://gallery.technet.microsoft.com/scriptcenter/d31f091f-2642-4ede-9f97-0e1cc4d577f3

After that I had to remove the remaining DNS stuff, and now everything 
seems to be in perfect shape, with dc2/dc3/dc4, replicating perfectly, 
no more errors.

After this excersize I dumped the entire active directory to an ldif:
ldbsearch --url=/var/lib/samba/private/sam.ldb > 
/root/samba4/samba4.ldif and grepped that file for "DC1", and I noticed 
that DC1 is still referenced to as "msSFU30MasterServerName" in 15 places.

I have asked this here before, but received no answers.

The question: can I simply replace "msSFU30MasterServerName: DC1" with 
"msSFU30MasterServerName: DC2", or is there other/more magic involved..?

And also...what does msSFU30MasterServerName actually mean/do?

Kind regards,
Mourik Jan
