Lightweight Directory Access Protocol - standard for accessing and maintaining distributed directory services. Like a phone book service for computer networks that helps find users and resources.
Companies use LDAP to manage employee directories and authenticate users across different applications.
LDAP is a protocol, not a cloud service. AWS Directory Service, Azure Entra Domain Services, and Google Managed Microsoft AD provide managed directory services that can be accessed via LDAP/LDAPS (often through Active Directory). OCI IAM is an identity service and does not provide a general-purpose LDAP directory; OCI customers typically integrate OCI with external directories (e.g., AD/LDAP) via federation or custom integration.
