Problem to login to OMV samba login with UCS LDAP

Hello UCS guys,
I’m getting crazy to be able to login to my OMV (Openmediavault 4) shares using my UCS domain master.
I successfully join the realm with the NAS under OMV, I can getent passwd/groups successfully, I see domain users & groups in OMV, but I can’t mount a samba share.
Every time on the samba side I got this error : check_ntlm_password: Authentication for user [my.user] -> [my.user] FAILED with error NT_STATUS_NO_LOGON_SERVERS.

I tried a TON of different configurations in addition to the smb.conf, but i get every time this error.
OMV 4 Samba version is 4.5 under Debian 9.

Does anybody already did this ? (the old topics from 2017 got no answers).

Thanks for your help.

SELF ANSWER :
I joined the domain with “realm join” and it seems to not force the DNS record of the machine on the DC.
I added the DNS record of the server and everything worked.

Good to read you were able to solve it. Also make sure your OMV has the UCS DCs set as DNS server, I’ve seen similar things happen in Windows AD environmetns with Linux systems joining it.

Maybe sssd was unable to tell UCS S4 to register the DNS record or S4 connector was unable to update the DNS zone at the level of OpenLDAP. (You could check the connector logs on the DC running S4 and / or the S4 connector)

Hello :slight_smile:
Yes my OMV got the DCs DNS.

I’ve got a LOT of logs because I tried a LOT of different things. So currently I don’t see anything about the DNS record, I can only see the sync of the cn=myOMV,cn=computers.
