What is the highest AD Forest functional level I can use and still have SAMBA 4 function as a domain controller. Can SAMBA 4 act as a domain controller in a Server 2012 functional level forest? Does functional level matter with SAMBA?

1 Answer 1


The Active Directory functional level cannot exceed (to be "supported") 2008 R2. It appears there are still issues with SAMBA4 + 2012 schema.
