Regarding User importing from Ldap or other scripts

Hi Team,

I am using a Ldap plugin for authentication inside the spring boot application.
This will authenticate and allow me to login in camunda web.
But there are no authorization entries that were made with when application startup.

I have created a sample application using spring boot, able to connect with Ldap and authenticated.
But it is not created any authorization entry.
I saw a few links like create a processes.xml and define XML tags with admin user name or group name that will create a authorization entries.

I also provided that in side my resources, classpath, inside package folder but camunda engine is not recognized and created the authorization entries.
Due to this, i am not able to see any UI, like tasklist, cockpit and admin.

So please help me to resolve this,

See the below xml file content.

<?xml version="1.0" encoding="UTF-8" ?>
<process-engine>
	<plugins>
		<plugin>
			<class>org.camunda.bpm.engine.impl.plugin.AdministratorAuthorizationPlugin
			</class>
			<properties>
				<property name="administratorUserName">demo</property>
			</properties>
		</plugin>
	</plugins>
</process-engine>

How do config that this xml file or where to place this file ,

Or is there is any different way to enable this AdministratorAuthorizationPlugin to create all-grant admin authorization entries in DB.

Camunda engine is running as spring boot application.

Please reply.
