[Samba] Samba seem to work fine but "cannot find my workgroup"

[Steffen Dettmer]

Hi,

I setup a new samba file server (in a priviledged Proxmox container using
the Debian 12 template) and apparently it works fine.

In log I see every 10 seconds:

  write_browse_list: Fatal error - cannot find my workgroup DMYDOM

Google found one hint telling it should set "network = ip", but man page
does not explain such an option. Another hint suggests it could be related
to an old smbv1 and can be ignored.

I have another server in another domain and I though it took over every single
option as it is (of course adjusting the domain to its correct value like
MYDOM), and on this other I don't see such messages.

Somehow the domain could be found I think, because there were no errors
when authenticating for admin commands like:

  root at samba1:/var/log/samba# wbinfo --ping-dc
  checking the NETLOGON for domain[DMYDOM] dc connection to
"realwin2019.DMYDOM.local" succeeded

  root at samba1:/etc# net ads join -U a-sdettmer
  Password for [DMYDOM\a-sdettmer]:
  Using short domain name -- DMYDOM
  Joined 'SAMBA1' to dns domain 'DMYDOM.local'

  root at nas1:/etc# net rpc rights grant "DMYDOM\a-sdettmer"
SeDiskOperatorPrivilege -U "DMYDOM\a-sdettmer"
  Password for [DMYDOM\a-sdettmer]:
  Successfully granted rights.

Did I miss something? What should I do?

Any help appreciated!

Steffen
