[Samba] Cannot find invalid DNS entry

[Tim Dittler]

Dear Roland,

Thank you for your help and sorry for the late reply.

If I understand you correctly, you ask me to drop dnsmasq from the config.
I believe, dnsmasq is necessary for our setup, since it is used to
forward queries about different domains to different DNS servers.
Also, the exact same setup is working fine on similar networks, without
giving the "TDB file" error.

Do you have another idea?

Best regards,
Tim

PS: NetworkManager is not running on the Ubuntu Server system.
