SPNEGO authetification


I have a dual stack installation (ABAP+J2EE) with an ABAP UME. I wish to implement LDAP authetification and understand that the configuration cannot be changed due to limitation imposed when the UME is ABAP. SPNEGO(kerberos) authentification is not ideal in our case (although it can be done) but I require the users to be prompted for username and password a second time opening portal session once they have been authetificated via the LAN due to security policy for ESS.

Is it possible to invoke a second challenge once authentificated via the LAN in a kerberos (SPNEGO) setup in the above scenario?
