An open standard protocol used to access and manage directory information services over a network.
Description
Lightweight Directory Access Protocol (LDAP) is a protocol used for accessing and managing directory services, which store information about users, groups, and resources in a network. In the context of Single Sign-On (SSO), LDAP plays a crucial role as it enables centralized authentication and authorization of users across multiple applications and services. LDAP allows organizations to maintain a single directory that holds all user credentials and attributes, simplifying user management and enhancing security. When a user attempts to log in, the SSO system queries the LDAP directory to verify the user's identity. This integration reduces the need for multiple usernames and passwords, streamlining the login process and improving user experience. Additionally, LDAP supports various platforms and systems, making it a versatile choice for organizations looking to implement SSO solutions while ensuring secure access to their resources.
Examples
- Active Directory: A widely used implementation of LDAP by Microsoft for managing user accounts and resources in Windows environments.
- OpenLDAP: An open-source implementation of LDAP often used in Linux environments for user management and authentication.
Additional Information
- LDAP operates over TCP/IP, making it suitable for operation over networks, including the internet.
- It supports secure communication through SSL/TLS, ensuring data privacy and integrity during user authentication.
