int applicationLogin	(	Application	this,
		Credential	credential,
		Session	session
	)

this is a user authenticated via another method than the password database and has not yet logged in. NOTE: first we have to remove the search user and as username is initialized with something that we will free later here we must set it to NULL so that the delete will not free it.

Todo:

Handle error...if this fails we have most likely a collision.
