Hi list, Very strange problem here on Samba 4.5.2 DCs. We have set up some GPOs and they seem to work fine, however we need to apply some Security Filtering to a couple of them. We can add groups and users until we reach 6 groups/users/computers in the list box in GPO management. As soon as we try to add a 7th entry, GPO Management throws an "Access Denied" error. Even odder is that sometimes if we do this, then delete a previous entry from the list, the most recent one will magically appear. We are managing AD using RSAT tools on Windows 7. Has anyone else come across this problem? Regards Alex -- This message is intended only for the addressee and may contain confidential information.

This a policy designed to revert a higher level enforcement of screensaver/locking for an ou containing servers, for a subset of those servers and for certain user groups. I'd already added one machine individually and one user group to the Security Filtering list. I needed to add another user group, one individual user and 8 machines - the group, user and the first two machines worked but I couldn't add any more after that. Restarting samba did not help :-( Cheers Alex -- This message is intended only for the addressee and may contain confidential information.

I once had a similar problem and it turned out as this:
A Microsoft security update for Group Policy changed the behavior of clients in
regards to GPOs:
MS16-072: Security update for Group Policy: June 14, 2016
https://support.microsoft.com/en-gb/kb/3159398
The following page explains the issues and the corrective measures.

In sum:
Add the Authenticated Users group with Read Permissions to the Group Policy
Object (GPO).
If you are using security filtering, add the Domain Computers group with
read permission.
