Can the Oracle Portal handle single sign-on to legacy applications?
The Oracle Application Server Single Sign-On environment supports applications which delegate their credential verification (partner applications) as well as those which retain their own authentication model (external applications). Legacy applications may integrate as partner applications by use of mod_osso (an Oracle Application Server HTTP Server mod) or by use of the Oracle Application Server Single Sign-On SDK.

These include the use o
