[Samba] smbXsrv_client_connection_pass_loop: smb2srv_client_connection_passed() failed => NT_STATUS_OBJECT_NAME_NOT_FOUND

[Jan Jurko]

 Good day.
For me it is very difficult to set up a new environment because all my users use live system (more tan 1000 users). I switched to 4.16.5 and there are no problems so IMO there is something between this and 4.17.0 what causes it.

Should I fill the bugreport?

Thank you
