The following realms are supported in the Application Server:
file – Stores user information in a file. This is the default realm when you first install the Application Server.
certificate – Sets up the user identity in the Application Server security context, and populates it with user data obtained from cryptographically verified client certificates.
solaris – Allows authentication using Solaris username+password data. This realm is only supported on the Solaris operating system, version 9 and above.
For detailed information about configuring each of these realms, see How to Configure a Realm.
