MongoServerError[Unauthorized]: not authorized on Database to execute command

Hi Team,

I have build mongoDB community edition and configured security setting in the DB conf file. After I started MongoDB. I created Admins. Finally tried to create database but getting the below error.

rs0 [direct: primary] admin> >use DBNAME
rs0 [direct: primary] DBNAME> db.student.insertOne({student_id:105,fname:“Rohit”,lname:“Agarwal”,course:“MySQL”})
