[Samba] Samba domain users AWOL from Samba file server.

[John Redmond]

Unfortunately, the the Ubuntu 18.04 samba-tool package doesn't have "user
show" as an option.  The Windows ADUC tool shows user1 uidNumber =10001,
user2 uidNumber=10002,  user3 uidNumber =10003, and user4 uidNumber=10004

Here are the getent command results on the file server/ domain member:

*admin at fsvr0:~$ getent passwd user1*
hq-user1:*:11103:10513::/home/lan/user1:/bin/bash
*admin at fsvr0:~$ getent passwd user2*
hq-user2:*:11106:10513::/home/lan/user2:/bin/bash
*admin at fsvr0:~$ getent passwd user3*
*admin at fsvr0:~$ getent passwd user4*
*admin at fsvr0:~$ getent group "Domain Users"*
domain_users:x:10513:user1,user2,user3,user4,administrator,krbtgt
