Single Sign on between Joomla and Wordpress

I have a wordpress instance installed in joomla's root folder, I would like to enable Single Sign On with joomla and wordpress. How do i do that. Also, i tried with开发者_StackOverflow attempting to access session value set in joomla page in my wordpress. But an not able to access it.

Appreciate any methods to enable Single Sign on bt/w joomla and wordpress.

Jfusion would probably be the easiest way to handle the dual login.
