show dbs gives “Not Authorized to execute command” error

Question

I\'ve spent some time trying to figure out what is wrong but as I could not find out, I decided to ask here.

I am running MongoDB(Windows 64-bit 2008 R2+) version 3.

Answer 1

Create a user like this:

db.createUser(
      {
        user: "myUserAdmin",
        pwd: "abc123",
        roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
      }
    )

Then connect it following this:

mongo --port 27017 -u "myUserAdmin" -p "abc123" --authenticationDatabase "admin"

Check the manual :
