How can I enter Mongo as a superuser or reset users? I'm was playing around with permissions and locked myself out of Mongo database.  I'm pretty sure I did this by trying to explicitly add access to a database but instead I overwrote only allowing permission to the database. So I'm effectively locked out of my Mongo database and everything I read tells me how to create a super user if I have the add user privilege.  Right now I don't think I have any users that have that privilege.  Is there a way to enter the database as all access?  I own the server and have root access.
If you have locked yourself out then you need to do the following:


Stop your MongoDB instance
Remove the --auth and/or --keyfile options from your MongoDB config to disable authentication
Start the instance without authentication
Edit the users as needed
Restart the instance with authentication enabled
