Coexisting with Non-Sun Deployments

Companies typically integrate OpenSSO Enterprise with non-Sun identity services for two purposes:

• To maintain backward compatibility with legacy applications in an existing environment

  In this use case, legacy non-Sun applications for authentication, authorization, and auditing have already been deployed and will continue to be used in the environment. OpenSSO Enterprise is used primarily to execute federation among both legacy and future applications. OpenSSO Enterprise may also be used for identity services when new applications are added to the environment.

• To facilitate complete migration from the non-Sun identity services to OpenSSO Enterprise

  In this use case, legacy non-Sun applications for authentication, authorization. and auditing have already been deployed. These applications must be maintained until OpenSSO Enterprise can be deployed and tested. Once OpenSSO Enterprise is successfully deployed, the legacy non-Sun identity services are phased out of the environment.
