[jicofo] Authentication Session sharing between Jicofo instances

Hello Everybody,

When multi shard is used (i.e. when multiple jicofo instances exist) and authentication enabled (ldap, internal, token etc.), how authentication session information is shared between jicofo instances?

When there is one jicofo instance, username and password is never asked during the authentication lifetime which is 24 hours.

However as far as I understand from the code, when there are multiple jicofo instances and the user is routed to different jicofo instances in his/her subsequent entries, username and password will be asked to the user again and again.
