That is what testparm shows if the default 'idmap config' line is not
set in the smb.conf file and that line is not and should not be in a DC
smb.conf file, so does your script run testparm ?

I do not get that error on my DC with the PDC_Emulator FSMO role, but I
am on 4.23.4 (latest Debian Trixie backports), so you might want to
upgrade.

I do not run sysvolreset that often, you only really need to run it
when you make major changes to sysvol and then, only if you get errors.
