lldap is a lightweight authentication server for self-hosted environments that need straightforward LDAP-compatible user management without the complexity of a full directory platform.
It deliberately provides a simplified and opinionated LDAP interface rather than attempting to implement every LDAP feature. A browser-based frontend handles routine user and group administration, while its API makes the service suitable for scripted provisioning and integration with other applications.
This is free and open source software.
