LDAP is primarily used as a repository for which type of data?

• A. System logs
• B. User emails
• C. Authentication and authorization data
• D. Application binaries

Answer: (C)

LDAP is a directory service designed to hold information about people, groups, and access control in a centralized, searchable way. Its primary use is as a repository for authentication and authorization data—storing user identities, group memberships, roles, and related attributes that systems consult to verify who a user is and what they’re allowed to do. This centralized store enables consistent login processes and access decisions across many applications and services.

System logs belong in log management or SIEM systems, not LDAP. User emails live in mail servers or mail stores. Application binaries are kept in code repositories or file stores. These data types aren’t organized for centralized identity and access management like LDAP is.
