An LDAP (Lightweight Directory Access Protocol) server works by providing a centralized repository of user, group, and device information for network-based services. It stores and manages directory information, such as system settings, email addresses, user profiles, and other data.
When a client application requests information from an LDAP server, it sends a query containing search criteria for the information it needs. The LDAP server then retrieves the requested information from its directory database and returns it to the client.
LDAP servers use a hierarchical structure to organize data, with the top-level directory representing the highest hierarchical level and subsequent levels representing subdirectories. This hierarchical structure allows for efficient organization and management of large amounts of data.
LDAP servers also use access control lists (ACLs) to control user access to data. ACLs specify which users or groups have access to specific directories or objects within directories. This ensures that sensitive data is protected from unauthorized access.
Overall, an LDAP server works by providing a secure, efficient, and centralized repository for managing network-based services and data.
