AppCenter includes built-in OpenLDAP with two users that you can use to get started with AppCenter before adding corporate LDAP users.
AppCenter uses your corporate LDAP for user authentication, and supports LDAP groups. You can add multiple LDAP configurations. You cannot delete users that you add. If a user is no longer part of a configured LDAP, AppCenter retains only the username in the app-service database to maintain their associated apps or scripts.
