Incidentally, I’m actually more concerned about groups than users. Users could reasonably want to do chgrp to adjust group membership of a file or directory, but they can’t do much about user. However it would be nice to see the real user as well.

Well, it should.  What happens is this:  After asking the non-AD LDAP
server for the account name, it asks the account fetching algorithm for
that name from scratch.  This depends on the /etc/nsswitch.conf
settings, of course (*).  Assuming "passwd: files db", it first checks
the local /etc/passwd file for a matching entry for that account name,
then the OS, preferring AD on an AD member machine, then local SAM.
