[Samba] Samba 4.10.6-1 Configuration on AIX

If you were up for another hint at rid versus ad... I'd like to understand a bit more.
With rid, I map the administrator to root only... no mapping of users in AIX.
How does Samba figure out that bobw at mydomain.com should use the samba user ID bobwsmb?
If I use ad, I would use rfc2307 attributes to address that (I think).
It seems more "specific" to use ad, but that's more from the "having some control" viewpoint than anything else.
Ideally, the customer would still strive for low administration, so is rid more suited for that approach than ad?
What are the reasons to use or choose to avoid rid or ad?
As always, your sage advise is very much appreciated!

If 'bobw' is in /etc/passwd and there is also a user in AD with the
samaccountname 'bobw', then delete the one in /etc/passwd. You cannot
have the same username in /etc/passwd and AD. If you add 'winbind use
default domain = yes' to your smb.conf, then 'mydomain\bobw' will become
just 'bobw'. For example, my record is in AD:
getent passwd rowland

You do not use usermaps any more, except for Administrator and yes, you
may have to chown file ownership. There is a way around this though, but
only if you have access to a domain DC, you give your users a uidNumber
attribute and Domain Users a gidNumber attribute and then use the
winbind 'ad' backend instead of 'rid'. You could use the IDs your users
already have, if you want to go down this path, we can discuss this further.

Definitely not, as you have seen, Unix knows who I am, but 'cat
/etc/passwd | grep rowland' returns nothing

Changing the idmap range would only be of use if the winbind 'ad'
backend is used, the 'rid' backend calculates the ID from the user or

Possibly, but I do not do mind reading ;-)
