Akonadi Server Self-Test Report
===============================

Test 1:  SUCCESS
--------

Database driver found.
Details: The QtSQL driver 'QMYSQL' is required by your current Akonadi server configuration and was found on your system.

StartServer=true


Test 2:  SUCCESS
--------

Akonadi is not running as root
Details: Akonadi is not running as a root/administrator user, which is the recommended setup for a secure system.

Test 3:  SUCCESS
--------

MySQL server found.
Details: You have currently configured Akonadi to use the MySQL server '/usr/sbin/mysqld-akonadi'.
