This thread hasn't seen any activity in several months, but I discovered it today after suffering from the same problem for the past few weeks on Lucid. After some trial and error I was able to resolve it. Winbind was unable to translate uids/gids into SIDs, but it could convert usernames into SIDs. The fix was to modify the idmap config from this syntax:
idmap backend = rid:FRIENDS=10000-20000 To this syntax: idmap backend = tdb idmap config FRIENDS : backend = rid idmap config FRIENDS : range = 10000-20000 And voila, winbind works correctly.
