That is actually what it does.
Akonadi is not autostarted nor restored on session restore. It is started by 
its clients on demand.

Basically, when an Akonadi client initializes a session with the Akonadi 
server, it will either connect to the running instance or start it if it is 
not running yet.

Assuming that your distributor didn't add an autostart script or similar to 
start Akonadi on login, this would indicate that some program that is part of 
your session startup is an Akonadi client and thus triggers Akonadi startup.

Unfortunately it seems to be impossible to get the connected applications from 
the socket in the file system, i.e. netstat or fuser will only list 
akonadiserver.

I think we currently have no direct way to list all open sessions either :(

What you could try is to run Akonadiconsole after login, enable the debugger 
and then restart Akonadi.
All clients should attempt re-establish their connection and their sessions 
should show up as tabs. That would be Akonadiconsole itself, all resources and 
agents and if you are lucky the client that caused the startup.

That setting is actually unrelated. It is part of the MySQL configuration, 
used to determine wether Akonadiserver should run its own mysqld instance or 
connect to an externally started one.
