All, 

So I followed the install process to a T, and it was going very well until I hit this:

./adduser.php <my username> <my Password> 10

Observium CE 0.16.1.7533

Add User

ERROR: no valid auth_mechanism defined.

I am running Debian 7 VM, and all dependencies are there. 

$config['auth_mechanism]         = "mysql"; 

is in the config.php

Anyone else run into this before?
