I have enabled authentication in the MongoDB config file after adding one admin user with the following privileges: userAdmin
and userAdminAnyDatabase
.
Now I connect with this user to the db where this admin user is defined (otherwise I get exception: login failed
).
After I have successfully connected I want to add the a new user to a new database. For that I am trying:
use another
db.addUser(...)
but I get an error:
Wed Dec 11 17:45:18.277 couldn't add user: not authorized for insert on app.system.users at src/mongo/shell/db.js:128
How can I create a new database and add a first user to it?
Detailed (all users have 1234 as password in this example)
$ mongo mono -u admin_all -p 1234
MongoDB shell version: 2.4.6
connecting to: mono
> db.system.users.find()

The mistake made was that I was using an userAdminAnyDatabase
user that was NOT in the admin database (see this note). So there MUST be a database called admin on your server! As the documentation says for the "AnyDatabase" privileges:
If you add any of these roles to a user privilege document outside of the admin database, the privilege will have no effect.
So you must:
add a userAdminAnyDatabase
to the admin
db
$ mongo admin
> db.createUser({ user: "myadmin", pwd: "1234", roles: ["userAdminAnyDatabase"] })
turn on authentication
auth = true
setParameter = enableLocalhostAuthBypass=0
connect using the new myadmin
user to any database you want and add further users:
$ mongo another -u myadmin -p 1234
> db.createUser({ user: "user", pwd: "1234", roles: ["readWrite"] })
or
> use another
> db.createUser({ user: "user", pwd: "1234", roles: ["readWrite"] })
