[Samba] Error joining Linux member to 4.5.0 DC: Indicates the SID structure is not valid

I use that because I've not see adequate load balancing otherwise (I 
provide a differently ordered list to half of the members).

No good reason.  No where near any of the limits.

Look through my recent posts, I'm having a ton of issues with Samba.  
Not sure what the root cause is, but I keep hoping one of these errors 
will lead someone to answer.  I've tried a lot on my own, but I can't 
figure it out.  The error seems the most revealing.  I'm wondering about 
the RID process / possible SID collision.  Now I can't join a Windows 
machine with my login either.

I added it as a test, I didn't have it before.  I don't want the 
Administrator account to even allow access on member Linux servers. I 
just use it for joining in scripts.
