Change to the directory RegistryDomain-base/domains/registry/applications/j2ee-modules/soar/WEB-INF/classes.
Open the file omar.properties in a text editor.
Add a definition of the following property:
omar.security.selfRegistration.acl
You can place this property definition anywhere in the file. A logical place for the property definition is in an area where other properties with the prefix omar.security are defined.
Define the property value as a comma-separated list of first and last names of people who are authorized to perform user registration, as in the following example:
omar.security.selfRegistration.acl=Vijay Patel, Jane Doe,
Save and close the omar.properties file.
Follow the instructions in To Stop and Restart the Application Server Domain for the Registry.
