I am a tad bit confused and am seeking clarification. Understanding that Cirrus can leverage Active Directory for user account authentication and password management, what does this mean? I am familiar with TACACS. Does this work similarly? Given a scenerio where I want to have different passwords on my Cisco devices, how do I manage this with Cirrus? For example, certain devices tier 2 and 3 should have access, however certain devices only tier 3 should have access.
