Hi @mohanad hassan , I unfortunately do not think this is possible with your current setup. The FAQ says that the two solutions for on-prem scenarios are:
- Deploy the Rights Management Connector on-prem
- Synchronize the AD Domain Controllers with AAD
But in the prerequisites to the Rights Management Connector, it says that you still need to synchronize with Azure AD. It's a cloud solution so it needs to be hybrid at minimum.
Please let me know if you have any questions! If this answer helped you, please mark it as "Verified" so other users may reference it.
Thank you,
James
