- Samba je členem domény: wbinfo -u a wbinfo -g vypisuje uživatele a skupiny. - v logu Could not get unix ID for SID ... moje SID z Windows AD - nsswitch nastaven podle návodu - krb5 nastaven podle návodu - smb.conf nastaven podle návodu - všechny návody z Wiki Samby. - DNS nastaveny podle Samba wikigetent passwd vrací jen lokální uživatele (rady na různých webech neppomáhají). getent passd domena\user nevrací nic Všechny další rady se už jen opakují a nevedou k cíli. Nemá někdo tušení, kde by mohla být chyba? Případně nějaký odzkoušený smb.conf?

Ano winbindd běží: wbinfo -u vypíše všechny uživatele z AD
Když dám do smb.conf: winbind use default domain = yes, tak vypíše jen uživatele (someuser). Když dám no, vypíše uživatele i s doménou INDOM\someuser

Pokud by bylo možné dodat funkční smb.conf, moc by to pomohlo ... ještě snad proměnné winbind v smb.conf

To tučně zvýrazněné jsem hledal v google naposledy a žádná rada nepomohla. Stále stejný stav.
PS: doména a uživatel je samozřejmě v reálu jiný. Tady jsem nahradil jsem doménu a uživatele jiným názvem./etc/nsswitch.conf

Do not add the winbind entry to the NSS shadow database. This can cause the wbinfo utility fail.https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Domain_Member jen pro info
winbind enum users
Mj, když se podívám na uživatele ve Windows serveru přes Editor atributů, žádné UID není nastaveno
V LOGulog.winbindd-idmap je: Could not get unix ID for SID S-1-5- ....-1121, což je SID mého loginu.
Když zadám getent groups "Domain Users", tak v LOGU je Could not get unix ID for SID S-1-5- ....-513, což je SID pro Domain Users.
Snažím se hledat, co způsobuje tuto chybu a zatím nic nepomáhá.

- If the Windows Active Directory Users and Computers (ADUC) program is not used, you have to manual track ID values to avoid duplicates.
- The values for the RFC2307 attributes must be set manually.
Missing Unix Attributes tab in ADUC on Windows 10 and Windows Server 2016Nevim, jestli jsem to pochopil spravne, jestli je opravdu u "ad" potreba rucne udrzovat cislovani uid guid... ale me to odradilo a pouzivam backend=rid...
