Not authorized for query on admin.system.namespaces on mongodb

Question

I start a new mongo instance, create a user, authorize it, but when I run \"show collections\", the system says that the id is not authorized. I do not know why?

Answer 1

I had the same problem and this is how I solved it:

db = db.getSiblingDB('admin')
db.addUser( 
    { user: "mongoadmin", 
      pwd: "adminpass", 
      roles: ['clusterAdmin', 'userAdminAnyDatabase', 'readAnyDatabase'] } )
