Explanation

TACACS+ (Terminal Access Controller Access Control System Plus) is an authentication protocol commonly used for network device access control (e.g., logging into routers and switches). It is designed with a modular architecture that supports integration with external back-end identity stores, including LDAP directories (such as Microsoft Active Directory). This allows organizations to centralize user credentials. ISAKMP is a key exchange protocol used in IPsec VPN setup, not an authentication database connector. PKI relies on certificates rather than LDAP lookups. CHAP is a challenge-response password protocol with no built-in support for external LDAP integration.
