Did you fix this by removing the TDB_CLEAR_IF_FIRST flag from tdb_open_log()
in winbindd_cache.tdb? This operation should be fairly quick and
definitely shouldn't take 12-15 minutes.
It strictly shouldn't be necessary to do this as you mention above but
it has been useful to delete the cache when changing the format of
entries in the cache between (development) versions of winbindd.
