#### To Create a Realm

The Application Server comes preconfigured with three realms: `file`, `certificate`, and `admin-realm`. It is also possible to create `ldap`, `JDBC`, `solaris`, and custom realms. Generally, you will have one realm of each type on a server, but on the Application Server there are two file realms: `file` and `admin-realm`. These are two realms of the same type used for two different purposes. It is also possible to have a different certificate database for each virtual server on your system.

1. Expand the Configurations node.
2. In the Cluster and Enterprise profile, select the instance to configure:
   - To configure a particular instance, expand the instance’s config node. For example, the default instance, `server`, expand the `server-config` node.
   - To configure the default settings for all instances, expand the `default-config` node.
3. Expand the Security node.
4. Select the Realms node.
5. On the Realms page, click New.

   The New Realm page is displayed.

6. Enter a name for the realm in the Name field.
7. Specify the class name for the realm being created.

   Valid choices are shown in the following table.

   Realm Name | Class Name
   --- | ---
   `file` | `com.sun.enterprise.security.auth.realm.file.FileRealm`
   `certificate` | `com.sun.enterprise.security.auth.realm.certificate.CertificateRealm`
   `ldap` | `com.sun.enterprise.security.auth.realm.ldap.LDAPRealm`
   `JDBC` | `com.sun.enterprise.security.auth.realm.jdbc.JDBCRealm`
   `solaris` | `com.sun.enterprise.security.auth.realm.solaris.SolarisRealm`
   custom | Name of login realm class

8. Add any desired optional properties for the realm.
   1. Click Add Property.
   2. In the Name field, enter the name of the property.

      - For a description of `file` realm properties, see Editing the File and Admin-realm.

      - For a description of `certificate` realm properties, see Editing the Certificate Realm.
