The user need to be created on admin db and give necessary privileges on the db you want to access
You have created it on test db and gave access to config db?

So i need to create user inside the admin db .
first i need to do mongo
use admin
create db flower;
then create user

db.createUser(
		{ 
			user: "rohan3",
			pwd:  "root3",
			roles:
			[
			{ role:"userAdmin",db:"flower"},
			] } );

This process i need to follow ?

Thanks for Time
