MongoDB shell authentication error

Question

I created a user and password for a database called student .:

db.createUser({user:'Catalin',pwd:'Catalin',roles:[{role:'userAdmin',db:'student'}]});

So I restarted MongoDB Server with this command:

mongod --auth --dbpath C:\data\db

in another terminal, I connected to the sever with:

mongo

then queried the server with :

> db.getUsers()
[
    {
            "_id" : "student.Catalin",
            "user" : "Catalin",
            "db" : "student",
            "roles" : [
                    {
                            "role" : "userAdmin",
                            "db" : "student"
                    }
            ]
    }

]

went to the student database:

> use student
switched to db student

Entered my username and password succesfully via this command:

> db.auth('Catalin','Catalin');

and when I want to view my collections I get an error, WHY?:

> show collections

The userAdmin built-in role only provides the ability to create and modify roles and users on a database. If you need access to the database, you would need to either assign database roles , or other roles that has database access such as dbOwner .

Please see Built-in Roles for more detailed information.
