How to deny add/remove members to AD Groups but still allow AD Group creation. -
Description
Denying Users permission to create Groups in Active Directory also allows them to populate the Groups during the creation, even when that User account does not have permission to modify the membership of a Group. -
Cause
This is by design, and is enforced at the Active Directory level. A single permission allows a User to both create a Group and also populate it during the creation as a one-time event. -
Résolution
There is no way by which to completely remove this feature, since it is enforced as a single permission on the Active Directory side.
WORKAROUND:
Use Active Roles to create a triggered Workflow which runs whenever a Group is created by the target Users. This Workflow will run an action and clear the Members attribute.
The effect of this Workflow is that users can create a Group and populate it with any accounts, but the populated members are immediately cleared when the Group is saved. Without the permission to Modify Groups, they cannot re-add any members after the Group is created.
This is possible to implement in Active Roles Server 6.7 with a simple PowerShell script.
In Active Roles Server 6.8 and later, this can be very easily implemented with an Update action.
