To administer security realms via the Geronimo Administration Console the Security Realms portlet is available on the Console Navigation menu on the left hand side. This portlet allows you to add a new security realm or edit an existing one. However, you will not be able to change the realm name nor the login domain name when editing an existing realm. To remove realms you would normally use the command line option with the Deployer tool.
Listed in this portlet you will find all the available security realms. By default, the security realm used by Geronimo to authenticate users via properties file is geronimo-admin.
When you create a new realm you will have to choose from the following realm types available:
The last available option lets you create your custom realm type when none of the above fits your environment needs.
