If you ran the Java ES Installer with the “Configure Later“ option, you must run the amconfig script to configure Access Manager after installation. To select Legacy (6.x) mode, set the following parameter in your configuration script input file (amsamplesilent):
... AM_REALM=disabled ...
On Windows systems, the configuration file is AccessManager-base\setup\AMConfigurator.properties.
For more information about configuring Access Manager by running the amconfig script, refer to the Sun Java System Access Manager 7 2005Q4 Administration Guide.
