This is a bit of a kludge, and I know I'm mixing and matching packages ...
but here we go.

I have Openmediavault systems, but with Louis 4.11 packages (so Buster-x86
+ Louis 4.11).  I'm finally trying to get Folder Redirection right, so am
configuring User Homes via

However, I'm having errors setting the actual Windows ACL, within

   - Connecting to my OMV server is fine, but opening "System Tools"
   complains of remote server Firewall and DCOM+ service errors.  Windows logs
   show "DCOM was unable to communicate with the computer <HOST>using any of
   the configured protocols; requested by PID      a90
   (C:\WINDOWS\system32\mmc.exe), while activating CLSID

Then, it connects and will show the Shares, etc.

   - At this point, I can edit and save Share Permissions, but attempting
   to change ACL's gives me "Failed to enumerate objects in specified
   Container. Access Denied." errors.
   - Additionally, in the Advanced portion of Permission Entry while
   attempting to add Domain Users, the bottom "add condition to limit access"
   shows "unable to contact Active Directory to access or verify claim types"

I've checked the following:

   - added SeDiskOperatorPrivilege to my account, Domain Admins, etc.
   - /etc/resolv.conf is pointing to my DCs
   - wbinfo -i (and other winbind) seems to work

In all other respects, this behaves like a Domain Member Server (RID).  Any
ideas why this is happening, or should I just use POSIX ACL's?
