Can a Django application authenticate with MySQL using its linux user?
MySQL controls access to tables from its own list of users, so it's better to create MySQL users with permissions.  You might want to create roles instead of users so you don't have as many to manage: an Admin, a read/write role, a read-only role, etc.
A Django application always runs as the web server user.  You could change that to "impersonate" an Ubuntu user, but what if that user is deleted?  Leave it as "www-data" and manage the database role that way.
The company I work for is starting development of a Django business application that will use MySQL as the database engine. I'm looking for a way to keep from having database credentials stored in a plain-text config file.
I'm coming from a Windows/IIS background where a vhost can impersonate an existing Windows/AD user, and then use those credentials to authenticate with MS SQL Server.
As an example: If the Django application is running with apache2+mod_python on an Ubuntu server, would it be sane to add a "www-data" user to MySQL and then let MySQL verify the credentials using its PAM module?
Hopefully some of that makes sense. Thanks in advance!
