Explanation

LDAP (Lightweight Directory Access Protocol) is correct because it is specifically designed to query and authenticate against directory services - like Microsoft Active Directory - which is exactly what an authentication server needs to validate user identities stored in a corporate directory. The key phrase in the question is "authentication server to the corporate directory," which points directly to LDAP's purpose as a directory access protocol.

TACACS+ (B) is a strong distractor, but it handles AAA (Authentication, Authorization, Accounting) between network devices and the authentication server - not between the auth server and the corporate directory. HTTPS (A) is a web transport protocol for encrypting HTTP traffic and has no role in directory lookups. SSH (C) provides secure remote shell access to devices but is not a directory query protocol.

Memory tip: LDAP literally stands for Lightweight Directory Access Protocol - if the question mentions a corporate directory or Active Directory, "directory" in the answer is LDAP.
