[Samba] Security permissions issues after changing idmap backend from RID to AUTORID
Thanks for the reply. Now we end-up with mix uid/gid from both ranges in cache TDBs. Few user logins are denied with below error in smbd.log, *[2016/01/07 11:39:44.475960, 1, pid=5202] ../source3/auth/token_util.c:430(add_local_groups* ** SID S-1-5-21-3082371790-1274690562-2878062458-5771 -> getpwuid(10005771) failed** wbinfo --user-info=mariond mariond:*:10015138:110000513:Marion, Deborah:None:None wbinfo --uid-info=10015138 mariond:*:10015138:110000513:Marion, Deborah:None:None If you notice above mappings, i.e a RID based UID is mapped to AUOT_RID based GID. Is there way to cleanup these mismatch uid/gid information in TDBs(like winbind_cache.tdb or gencahe.tdb) or remove all TDBs start afresh.
