Explanation

TACACS+ (Terminal Access Controller Access-Control System Plus) authentication support was introduced in PAN-OS 7.0. RADIUS and LDAP had been supported in much earlier PAN-OS versions and were already well-established features before 7.0. Diameter is a networking protocol used in telecommunications (successor to RADIUS for carrier networks) and is not a supported PAN-OS management authentication method. TACACS+ is commonly used in enterprise environments for device administration because it separates authentication, authorization, and accounting and encrypts the entire payload.
