第2章 Creating a realm and a user
The first use of the Red Hat Single Sign-On admin console is to create a realm and create a user in that realm. You use that user to log in to your new realm and visit the built-in account console, to which all users have access.
2.1. Realms and users
When you log in to the admin console, you work in a realm, which is a space where you manage objects. Two types of realms exist:
Master realm- This realm was created for you when you first started Red Hat Single Sign-On. It contains the admin account you created at the first login. You use this realm only to create other realms.
Other realms- These realms are created by the admin in the master realm. In these realms, administrators create users and applications. The applications are owned by the users.
