Am attempting to install SCCM 2012 R2 onto a member server in a domain with a Samba4 DC. I have every reason to believe that AD is working: smbclient reports (what I believe) are the appropriate shares and
kinit gives me a ticket.
When I go to install SCCM it gets as far as the 'begin installation' step and then I get this popup:
Domain <name> is not an Active Directory domain, you cannot use advanced security at this site.
I've tried disabling the firewall on the system I'm installing on and the requisite ports appear to be available on the DC (from the list on this page).
What other tests could I run to get past this issue?
