Problem with Pandora FMS auth system

Cannot connect to the database, please check your database setup in the include/config.php file or read the documentation on how to setup Pandora FMS.

Probably one or more of your user, database or hostname values are incorrect or the database server is not running.

MySQL ERROR: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

If you have modified auth system, problem could be because Pandora cannot override authorization variables from the config database. Remove them from your database by executing:

DELETE FROM tconfig WHERE token = "auth";
