It didn't change, it was my copy+paste mistake.  (At the time, the UID 
from the "broken" state was outside of my terminal's scrollback range; I 
thought it was 2018 but I was wrong; it was 2020 all along.)

All of my users seem to have entries in winbindd_idmap.tdb, actually; not 
just the ones that have UID-changing problems.
