Sorry for the delay, I have been out of town. Your hunch was correct,
Rowland. Both getent and id only return local machine accounts, not
domain accounts. What have I overlooked which would cause this? I do
have winbind in my PAM configuration.

James, it has worked for a few years. It recently (in the last year)
started having workstations report being unable to access the gpt.ini
files. The information you requested is below. This has not been altered
by me, it was setup this way when Samba was installed.

        path = /samba/var/locks/sysvol
        read only = No
