Documentation for Crowd 1.2. Documentation for other versions of Crowd is available too.

CrowdID is a free add-on that ships with Crowd versions 1.1 and later.

By default, CrowdID in the Crowd 'Standalone' distribution is shipped preconfigured with HSQL. This is fine for evaluation purposes, but for production installations, you should connect CrowdID to an enterprise database. This also lets you take advantage of existing database backup and recovery procedures.

The following instructions will allow you to configure CrowdID to an external database:

Database Overview

CrowdID in the Crowd 'Standalone' distribution includes the Apache Tomcat application server and an in-memory HSQL database engine. This JNDI reference (CrowdIDDS) can be adjusted to use your custom database and driver by editing the crowd.xml deployment description.

You will also need to edit the file build.properties, and run the script  build.xml, as described in 4.1 Important Files. The two relevant properties in the build.properties file are:
  • hibernate.dialect
  • hibernate.transaction.factory_class

These are described as follows.
