What I cannot understand is why the OP is still using Centos 6 and why
did they compile an EOL version of Samba initially ?

The configs shown have nothing wrong with them, but the one we need to
see, smb.conf, isn't provided, this may help in deciding the next step.

I think what Louis is suggesting is probably the way to go, upgrade
Samba on the original DC, but only after showing us the smb.conf.

He should also consider moving to Centos 7 as well.
