To configure Active Directory authentication for VPN authentication on a Cisco Secure Firewall Threat Defense (FTD) instance registered with Cisco Secure Firewall Management Center (FMC), the administrator needs to configure Realms in the System settings of the FMC. Realms in FMC are used to define the directory servers (e.g., Active Directory) and how they are used for user authentication.

Steps to configure this in FMC:

Navigate toSystem > Integration > Realms and Directory.

Add a new realm and configure the necessary details such as the directory server type (e.g., Active Directory), server address, and bind credentials.

Test the connection to ensure it works correctly.

This setup allows the FMC to authenticate VPN users against the Active Directory, thereby enabling secure access control for VPN connections.
