Before you install and configure OpenSSO Enterprise, here are a few changes to consider:
You install OpenSSO Enterprise from the opensso.war file, using the web container administration console or deployment command. You no longer run a standalone installer.
You initially configure OpenSSO Enterprise using the GUI or command-line Configurator. Then, to perform additional configuration, you use either the Administration Console or command-line utilities such as the new ssoadm utility. You no longer run the amconfig script with the amsamplesilent file.
Configuration data, including policy agent configuration data, is stored in a centralized repository. This repository can be either Sun Java System Directory Server or the OpenSSO data store (which is usually transparent to the user). OpenSSO Enterprise does not use the AMConfig.properties or serverconfig.xml files, except for co-existence with previous versions of Access Manager.
