LDAP

LDAP (Lightweight Directory Access Protocol) is an industry-standard application protocol for accessing and maintaining distributed directory information services over an IP network, formally specified in RFC 4511. It plays a critical role in protecting organizational assets and maintaining a strong security posture through centralized authentication, authorization, and identity management. LDAP underlies directory services such as Microsoft Active Directory, OpenLDAP, and 389 Directory Server, and is widely used for single sign-on, enterprise address books, and application identity stores.

LDAP publishes 1 API on the APIs.io network. Tagged areas include Authentication, Authorization, Directory Services, Identity Management, and LDAP.

LDAP’s developer surface includes documentation, engineering blog, and 4 more developer resources.
