Hi,
I am trying to test out the use of Group Policy for winbind clients as added in the latest samba version: 4.14.0 Following the
WiKi at https://wiki.samba.org/index.php/Group_Policy I have set up a client (running Debian Buster and Samba 4.14.0 from Louis'
repo) by adding the required line to the global section of smb.conf (apply group policies = yes). The domain controllers have
also been updated to 4.14.0 and the samba admx file has been added to sysvol. I have configured a setting for smb.conf using the
Group Policy Editor from Windows and the client machine has been added to an OU with the policy applied. I have restarted smbd and
winbind on the client. When I enter samba-gpupdate I get the following error:
root at moggy:~# samba-gpupdate

If I provide the Administrator user and password the error changes to:
root at moggy:~# samba-gpupdate -Uadministrator

Message was: Failed to load SamDB for assigning Group Policy
A reboot of the client did not improve matters. I tried adding the line: 'allow group policies = yes' to the domain controllers'
smb.conf but that did not make any difference either. I am obviously missing something, any advice will be appreciated.
