How to enable authentication in MongoDB?

I've been asked this question several times, it is simple indeed, but apparently it is causing some problems!
Here are some simple steps:
First fire mongo shell and create the user account

use admin
db.addUser('admin', '12345')
Then shutdown the server and exit:
Then you need to start the service with --auth parameter or add auth = true entry to the config file (e.g. in /etc/mongodb.conf). You're done! To see how this works, you can lunch MongoDB shell in two way:

mongo localhost:27017/admin -u admin-p 123456

Notice the admin (which is the db name).
Alternatively you can run the shell and then authenticate there:

use admin

Also in your code, you can specify the username and password e.g. this way in your Python code:

conn = pymongo.MongoClient("mongodb://username:password@localhost:27017")
