Hi to all and many congrats for this project!
I’ve started as MSWin admin, but now my big intention is to replace as many win services with linux ones wherever possible.
This is my first post and I would like to share my scenario and discuss it’s feasabilty whit you.
So, my big client has one central location and several remote ones. We all agree that there is no adequate replacement for every piece of Win mosaic, but as someone has mentioned , not every part of MS services/fetaures are used by clients (and for many of them the clients (even admins 
are not avare of) . So with linux offer (i.e. NS) we can reach kind’a “high score”. At this client of mine all crucial Win apps and services are hosted on central location and there is MS-AD/TS/SQL unavoidable and reachable through site-to-site vpn from remote locations. But, on remote locations only filesharing service is needed and at the moment there is still old w2003 server hosting AD and File/Print sharing. Since we must migrate to w2012 on central location and have to leave w2003(EOL) generation on remote locations, I’m loking for MS replacement for remote location. I’ve installed NS in my lab and tried some scenarios but as far I know , NS server cannot act as additional DC , what is very important in this scenario. Am I right ? So it seems that NS can act only as remote fileserver , joined to the MSAD domain , which is also very useful if interlocation links are enough fast.
So the main question would be whteher NS can play RemoteDC role ?
Many thanks in advance for your answer
Till then
Best regards
