[Samba] Domain Join fails w/ Samba4 to AD

[Cam Clayton]

Hello,

I’m unable to get Samba4 to join an existing AD domain as a DC. Running a Win2k12 R2 Server as primary.

This is a test server, before rolling it out live to a remote location.

it at testdom:~$ sudo samba-tool domain join example.com DC -Uadministrator —realm=example.com --server "ad.example.com" --dns=SAMBA_INTERNAL -WEXAMPLE
[sudo] password for it: 
Password for [EXAMPLE\administrator]:
workgroup is EXAMPLE
realm is EXAMPLE.com
checking sAMAccountName
Adding CN=TESTDOM,OU=Domain Controllers,DC=example,DC=com
Adding CN=TESTDOM,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=example,DC=com
Join failed - cleaning up

Any ideas?
