How LDAP and Active Directory Power Identity Management in Self-Hosted Platforms

LDAP and Active Directory integrations allow self-hosted collaboration platforms to authenticate users against an organization's existing corporate directory, eliminating the need for separate account databases. LDAP is a standard protocol for querying directory services, while Active Directory is Microsoft's broader enterprise identity platform that exposes directory data via LDAP. These integrations enable centralized control over user authentication, group permissions, profile synchronization, and employee offboarding across messaging, file, and video collaboration tools. The depth of integration varies by product — some platforms use LDAP only for login, while others support scheduled sync, role mapping, and automated account deactivation. IT teams evaluating platforms are advised to look beyond basic LDAP support and assess how quickly access is revoked, how groups affect permissions, and how the system behaves if the directory goes offline.
