In SOSDistributedSessionDAO old session may remain in Database

Current Situation

When using SOSDistributedSessionDAO in shiro.ini.active it may happen that sessions do remain in the database. This can be verified by locking into the table JOC_CONFIGURATIONS where the sessions are stored

Desired Behavior

JOC should maintain old sessions automatically. This should be done during the logout where all sessions that are timed out will be removed from the database.
