Can the Portal handle single-sign on to legacy applications?
The OracleAS SSO environment supports both applications which delegate their credential verification to the SSO server (Partner applications) and those which retain their own authentication model (External applications). Legacy applications may be integrated as partner applications by use of mod_osso (an OracleAS HTTP Server mod) or by use of the Single Sign-On SDK. However, if this is not possible, the External application model allows for the integration of applications with their own credential checks by storing the usernames and passwords and performing an automated login on behalf of the Portal user. If the legacy application is non-web based, such as client/server, it is still possible to integrate the application into the SSO environment through extensions such as meta-frame integration.
