OpenSSO Enterprise supports both version 3.0 and version 2.2 agents in the same deployment. The version 2.2 agents, however, must continue to store their configuration data locally in the AMAgent.properties file. And because the version 2.2 agent configuration data is local to the agent, OpenSSO Enterprise centralized agent configuration is not supported for version 2.2 agents. To configure a version 2.2 agent, you must continue to edit the agent's AMAgent.properties file.
For documentation about version 2.2 agents, see http://docs.sun.com/coll/1322.1.
