The Lightweight Directory Access Protocol (LDAP) is an application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network.
Directory services may provide any organized set of records, often with a hierarchical structure such as a corporate email or telephone directory. LDAP is an IETF standard and the latest specification is Version 3, published as RFC 4511.
LDAP in the Gluu Server
OpenLDAP is used as the persistence layer for the Gluu Server. User and session data is stored locally in Gluu’s LDAP server in order to speed up authentication and authorization transactions. It would be inefficient to call a backend system each time user information is requested by an application.
To manage your Gluu Server OpenLDAP installation, visit the OpenLDAP docs.
LDAP should not be used as an application integration protocol though. Applications should stick to SAML or OpenID Connect for interacting with the Gluu Server. Learn more about integrating applications with the Gluu Server using SAML and OpenID Connect in the Gluu Server CE docs.
