[Samba] Admin UID changed with upgrade to 4.8.2

[Mark Foley]

In order to get help using a more up-to-date version of Samba, I've just upgraded from 4.4.16
to 4.8.2. So far, nothing new seems to be broken, but I still have to track down some issues
I've been having.

First off, I notice that something has changed with my BUILTIN\administrators ID. before, I
had, e.g.:

> ls -l
/var/lib/samba/sysvol/hprs.local/policies/\{B78D19CB-914B-48F4-AA63-FD8708A553D7\}/Machine/
total 16
drwxrwx--- 3 BUILTIN\administrators users 4096 2014-09-13 03:22 Microsoft/
-rwxrwx--- 1 root                   users  958 2014-09-13 04:01 Registry.po*
-rwxrwx--- 1 BUILTIN\administrators users  958 2014-09-13 04:01 Registry.pol*
drwxrwx--- 4 BUILTIN\administrators users 4096 2014-09-13 03:22 Scripts/

Now, with 4.8.2, doing the same ls gives me:

> ls -l
/var/lib/samba/sysvol/hprs.local/policies/\{B78D19CB-914B-48F4-AA63-FD8708A553D7\}/Machine/
total 16
drwxrwx--- 3 3000000 users 4096 2014-09-13 03:22 Microsoft/
-rwxrwx--- 1 root    users  958 2014-09-13 04:01 Registry.po*
-rwxrwx--- 1 3000000 users  958 2014-09-13 04:01 Registry.pol*
drwxrwx--- 4 3000000 users 4096 2014-09-13 03:22 Scripts/

Is this a problem? Why would that user now be missing? What should I do about this?
