We do not support the LDAP protocol directly, so applications must communicate to Stormpath via API calls. However, we do offer AD/LDAP integrations. Stormpath can mirror your on-premise AD or LDAP user base.
Connecting new web and mobile applications outside the firewall to on-premise Active Directory or LDAP servers is difficult, time-consuming and sometimes impossible. With Stormpath, you can seamlessly connect your web or mobile applications to existing Active Directory/LDAP servers.
