When enabling PingFederate authentication sessions, you can select the persistent option so that PingFederate can leverage previous sessions as users request protected resources after restarting their browsers.
This optional persistent configuration requires external storage of session-state data, as opposed to in-memory alone. By default, PingFederate uses its internal HSQLDB database to maintain persistent authentications. You can configure PingFederate to maintain persistent authentication sessions externally on a database server or a PingDirectory server. Also, the PingFederate SDK lets you use custom solutions for persistent session storage.
Use the built-in HSQLDB only for trial or training environments. For testing and production environments, always use a secured external storage solution for proper functioning in a clustered environment.
Testing involving HSQLDB is not a valid test. In both testing and production, it might cause various problems due to its limitations and HSQLDB involved cases are not supported by PingIdentity.
- Create the required data structure on the external storage medium.
- Modify two PingFederate configuration XML files.
