Upgraded to v6.10.0 - My Nextcloud VM stopped working

Hi

Some explanation is needed:

I run a (Hansson) Nextcloud VM on VMWare Vsphere server. The server has a smb network share (called nextcloud) on my Unraid server.

The Unraid SMB settings is set to use Active Directory.

I have created a AD initial owner in AD (unraid_admin) and a AD initial group (UNRAID-DEFAULT-RW).

In addiction, I have added a user called nc_admin that is actually used to map up the share from the Nextcloud VM.

This works fine as long as I use Unraid v6.9.2.

Using smbstatus, it looks like this:

root@Unraid:~# smbstatus

Samba version 4.12.14
PID     Username     Group        Machine                                   Protocol Version  Encryption           Signing

When I upgraded to Unraid 6.10, this stopped working, and smbstatus shows me nothing at all.

I'm not able to map up the nextcloud share from a regular Windows PC either (using the nc_admin user). unraid_admin and Administrator is still able to map it, though.

So the question is, are there any significant changes in SMB that causes this, or is it a bug?

Thanks
