You can create a P-asserted identity trust configuration in one of these ways:
In the Admin Console, open the Security component under the relevant configuration and go to the Trust Configurations page. For details, click the Help button in the Admin Console.
Use the asadmin create-trust-config command to create trust configurations on local servers. For details, see the Sun GlassFish Communications Server 2.0 Reference Manual.
The default trust handler trusts all hosts and maps the P-Asserted-Identity header values to a format suitable for use in authentication and authorization tasks. For example, Cullen Jennings is mapped to CullenJ. To create a custom trust handler, see Creating a Custom Trust Handler for P-Asserted Identity Authentication.
