Hi All,

a happy new to all who already reached 2022...

I've just played on a member server with DFS. The member server is 
working correctly with winbind etc. and file shares.

The moment I added the dfs_samba4 to vfs object as mentioned in wiki, 
the member server stops to work.

Testparm shows no error:
Load smb config files from /etc/samba/smb.conf
Loaded services file OK.
Weak crypto is allowed

In logs I get the following errors:

   samdb_connect failed

Dec 31 17:51:14 GalacticaTest smbd[1290]:   samdb_connect failed

The moment I remove the dfs_samba4 from vfs objects the server is 
running again and even the dfs share is working.

Server is Debian 11 based with Samba 4.15.3 installed by Louis' repository..
