[Samba] getent not returning users/groups

[Gregory Sloop]

I sure hate to put anyone out a bunch of trouble if I've borked something up, but for the life of me, I can't see anything I've got wrong.
 
---
Can I recap a few things, to make sure I understand things correctly.
 
-If KBR was setup wrong or otherwise screwed up, we wouldn't be able to join the domain, right?
-Same thing for NTP, right?
 
And there's no way to see if/how the nsslib-winbind is talking to winbind itself, right. (I assume the lib talks to winbind and pulls the data. So, if the library is having difficulties, seeing what's going on inside the black box, would be handy.)
 
Thanks for the help so far.
 
(BTW, when I started down this road, I was on Louis's 4.15.3, and then when checking and double-checking things (when getent wasn't working), I upgraded to 4.15.5, in case it matters.)
