OpenLDAP is an open-sourced tool offering a cost-effective, versatile, and operating-system independent implementation of the Lightweight Directory Access Protocol (LDAP). Since its launch in 1998, it has become a top-rated choice for those seeking to use the LDAP protocol due to its affordability, adaptability, and compatibility with various operating systems.

One of the key features of OpenLDAP is its ability to unify authentication. It serves as a single source of authentication which can be connected with any software that supports the LDAP protocol. This centralization simplifies process management and enhances security.

Additionally, OpenLDAP includes phpLDAPadmin, a user-friendly web-based tool for managing LDAP data. Known as 'PLA', this feature allows system administrators to effectively manage their data. The intuitive design means it's not only system administrators who can benefit from this tool, but end users too. They can manage their data on an LDAP server with ease using PLA.

With 405 GitHub stars and the latest commit on 2023-07-31 the project looks healthy.
