If your enterprise already has a single sign-on mechanism in place for its users, you can customize Enterprise Portal to:
Use the existing single sign-on mechanism to guide an authenticated user seamlessly into the portal without having to log-in again, and
Modify EP so that when a previously anonymous user is authenticated by the portal, your single sign-on token is generated, which allows this user single sign-on access to other services in your enterprise.
The instructions in this section assume that the developer
fully understands the existing single sign-on system and its Java-based programming
interface. This knowledge is necessary to modify portal JSPs to
use that Java API to participate in an existing single sign-on or
to generate a new single sign-on token for a user.
