Specifying a security domain for deploying an application
You can use security domains to configure the security settings for a set of applications that are deployed on WebSphere Application Server.
If you have security domains that are configured in your IBM® WebSphere® Application Server environment, you can select the security domain that you want to use in the Configuration and Deployment Tool. If the security domain is not mapped to the server or cluster where you deploy your application, the Configuration and Deployment Tool updates the definition of the security domain to include the mapping.
If you do not have any security domains that are configured, the global security settings for the application server are used.
For more information about security domains, see the following topic in the IBM
WebSphere Application Server documentation: Multiple security domains
