[Samba] Samba 4.10.6-1 Configuration on AIX

Thanks for everything!

If I understand correctly, let's say that the user mydomain\bobw is the domain login.
Let's say that bobw is my UNIX login ID.
I can’t use bobw in my usermap file?
So I need to change my shares to a new ID and set that in my usermap file?

I don’t need to add bobw_smb to /etc/passwd?
Or do I need to add the user and need to set idmap user range to a range to be used for samba users?
Anything else I may be missing?

Thanks again for your patience!

If by this, you mean that you do not have to add anything to AD, then 
yes. You may have to add a couple of template lines to your smb.conf, 
the defaults are:

template homedir = /home/%D/%U

template shell = /bin/false

With the above, your users will not be able login to the Unix computer 
and will get a Unix homedirectory of /home/DOMAIN/username

You do not use smbpasswd and you need something else in smb.conf:

username map = /etc/samba/user.map

With '/etc/samba/user.map' containing '!root = DOMAIN\Administrator'

After this, using the 'rid' backend, all users and groups in AD become 
Unix users and groups.

Basically it boils down to, forget most of what you know about Samba3 
domains ;-)

Yes, it is just a different winbind backend.
