Re: [Samba] join samba to an existing AD failed




The user vdsadmin has been add to domain administrators group when I built my domain. It should have all required permissions, I think.
I want to join the new DC to a AD that also based on samba 4.8.3. The new DC and the existing AD are both samba 4.8.3 installing on centos 7.1.
