[Samba] WERR_DS_DRA_MISSING_PARENT error when joining new DC

[DreamySurfer212]

When trying to join a new DC to an existing Samba4 domain, I am getting this WERR_DS_DRA_MISSING_PARENT error. Does any have any suggestions on how to fix it? My original 6 dc's are running the last free Sernet (4.2.14)  on CentOS6 and the error occurs if I use Sernet 4.2.14 or 4.7.5-Debian. I finally have time to upgrade and something is broke.

Thanks,
Steve
