In preparation to bring outsourced Exchange in house, we are bringing up a proper Windows Server 2012 DC and AD. Company operates a hybrid Linux/Windows network with Samba providing main Windows integration capability. We are basically working on reversing the relationship: i.e. Windows Server 2012 DC and AD w/ Exchange with majority of user workstations Windows and majority of LAN server resources Linux (CentOS mostly), including the NFS.
In order to avoid realigning the bulk of the existing NFS, especially user home directories, I am trying to find out whether or not I can set new AD objects (users/computers) with old SIDs. I know that the ADMT worked to migrate AD-like objects from Samba 3(maybe 4) to Server 2008, but as of yet I have not heard of ADMT's availability on Srvr2012 or it's equivalent.
Any suggestions would be helpful, but I accept at this point that I might have to re-create the whole thing...
