Using Authentication Chaining

Authentication chaining provides a higher level of security than the regular mechanism of authentication. You can enable users to be authenticated against more than one authentication mechanism.

The procedure described in this is only for enabling authentication chaining along with a Personal Digital Certificate (PDC) authentication at the Gateway. For information on authentication chaining without PDC authentication at the Gateway, see the Access Manager Administration Guide.

For example, if you chain the PDC and Radius authentication modules, the user will have to authenticate against all three modules to access the standard Portal Desktop.

See To Add Authentication Modules to an Existing PDC Instance for steps.

When enabled, PDC is always the first authentication module to be presented to the user.
