Rockstor (Samba) as domain controller


I just like to know if it’s possible to configure Rockstor as PDC.
Currently I can’t find any options for domain provision, is it possible to do it manually?
Are there effects for samba configuration gui?

It is totally possible do achieve this manually. Samba related features on the GUI mostly confine to [shares] section with the exception of setting Workgroup or if you configure AD. But if you make Rockstor as PDC, you probably won’t be doing that. Hope that answers your question.
