Explanation

Active Directory (AD) uses the LDAP (Lightweight Directory Access Protocol) to expose directory information including user accounts and group memberships. Palo Alto firewalls communicate with AD via an LDAP Server Profile configured in the Authentication Profile. RADIUS (B) is a generic AAA protocol and does not natively speak to AD's directory structure. TACACS+ (A) is used for device administration. SAML (D) is a federated identity standard, not a direct AD integration method.
