Example: MongoDB: db.dropUser() method

The user mynewuser in the test database.

> db.getUser("mynewuser");
{
        "_id" : "test.mynewuser",
        "user" : "mynewuser",
        "db" : "test",
        "roles" : [
                {
                        "role" : "read",
                        "db" : "assets"
                },
                {
                        "role" : "read",
                        "db" : "orders"
                },
                {
                        "role" : "readWrite",
                        "db" : "test"
                }
        ],
        "customData" : {
                "employeeId" : "0x3039"
        }
}

The following db.dropUser() operation drops the mynewuser user on the test database.

use test
db.dropUser("mynewuser", {w: "majority", wtimeout: 4000})
