How to start Mongo daemon with auth support
I just tested this with a fresh Debian 7 install, and a fresh install of MongoDB. I added a user (adam) first, then edited the /etc/mongod.conf file to uncomment the auth = true line. I then issued the service mongod restart command and attempted to log in as the user, and succeeded - I also tried incorrect credentials and failed. Hence, authentication seems to be working just fine, there were no obvious problems using the config file to specify authentication is enabled.
So, a couple of questions:
- How are you testing that authentication is enabled?
- Do you perhaps have more than one line in your config file that ontains auth/noauth statements?
For reference, here's most of my testing with the feedback from the shell etc.
First, the install and setting up the initial user:
root@deb7:~# apt-get install mongodb-org
Reading package lists... Done
Building dependency tree

The following extra packages will be installed:
mongodb-org-mongos mongodb-org-server mongodb-org-shell mongodb-org-tools
The following NEW packages will be installed:
mongodb-org mongodb-org-mongos mongodb-org-server mongodb-org-shell
mongodb-org-tools

Next up I edited the /etc/mongod.conf file and removed the # that commented out auth = true (I made no other changes). I saved that file and then restarted the service. Next I connected with the user I had added and verified that I had the right provileges:
root@deb7:~# vim /etc/mongod.conf
root@deb7:~# service mongod restart
[ ok ] Restarting database: mongod.
root@deb7:~# mongo -u adam -p password123 --authenticationDatabase admin

Error while trying to show server startup warnings: not authorized on admin to execute command { getLog: "startupWarnings" }
As you can see, the user I added does not have the privileges to look at the startup warnings, but just to be sure, I checked the privileges:
> use admin
switched to db admin
> db.runCommand( { usersInfo:"adam", showPrivileges:true } )

Just for completeness, here's an auth failure:

exception: login failed
Edit /etc/mongod.conf and add a line like this:
For mongo <3.0
auth=true
Then:
service mongod restart
For mongo 3.x, Add this to the config
security:
authorization: "enabled"
