Thanks to you and Louis for your guidance.
I really apologize for my lack of knowledge of AD and Samba; and I appreciate your patience and willingness to help.
And I apologize for not trimming the reply - don't know how much to retain...
The referenced document seems to be leveraging domain services that we're not using.
We are only using AD user authentication to access shares on AIX.
No single sign-on, no user administration/manipulation anywhere, no printer sharing.
Kerberos shouldn’t be required, which one might think also means the imap settings shouldn’t be required.
Although they may eventually embrace NTP, is it not configured today; without Kerberos, it isn’t required.
We're not wanting to save any user credentials necessary in AIX to acquire access to the shares in AIX.
Testing DNS, everything is good until the "set type=SRV" _ldap_... test; it fails.
Kerberos is not installed on AIX.
The server name (hostname) was changed from the old FQDN to the new FQDN, and the /etc/hosts file was updated.
The security was changed from domain to ADS.
Testparm still reports the imap errors (see below).
Load smb config files from /etc/samba/smb.conf

Wrong security, it should be 'ADS' against an AD domain

Try reading our documentation:

You need to fix your smb.conf, join the machine to the domain and start,
smbd and winbind, you can also optionally start nmbd.

The above is because your smb.conf 'idmap config' lines are not set
