In the integration between Cisco Identity Services Engine (ISE) and Cisco Firewall Management Center (FMC), realms are used to define the Active Directory (AD) configuration. Realms in FMC specify the AD servers, domain, and other authentication settings necessary to authenticate and authorize users.
Steps to configure realms:
In FMC, navigate toSystem > Integration > Realms and Directory.
Add a new realm and configure the AD settings.
Ensure the realm settings match the AD environment for seamless integration.
Realms are essential for integrating AD with FMC, allowing the firewall to use AD for user authentication and policy enforcement.
