Does Cisco Security Manager 4.x and Cisco Secure Access Control Server 5.x integrated role based administration has fine-grained control for devices? E.g.,
* User-a can only manage policy-a for device-a
* User-b can only manage policy-b for device-b
ACS 4.2 should allow role-based access, but until the final build of CSM 4.0 is released this cannot be confirmed.
I am not aware of plans to add the support within ACS 5.x, but you can always engage your Cisco account team to submit a product enhancement request on your behalf.
