Authorizer Configuration
An 'authorizer' grants users the privileges to manage users and policies by creating preliminary authorizations at startup.
Authorizers are configured using two properties in the nifi.properties file:
- 
            The nifi.authorizer.configuration.fileproperty specifies the configuration file where authorizers are defined. By default, the authorizers.xml file located in the root installation conf directory is selected.
- 
            The nifi.security.user.authorizerproperty indicates which of the configured authorizers in the authorizers.xml file to use.
