I need to connect users joomla in wordpress

Hello, I've been searching through the forum of joomla and its extensions, and I've only found this extension called JFusion (url: http://www.jfusion.org)
I tried to configure this extension so that the joomla is the master website and wordpress (cimaw.com) is the portal that will receive joomla users.
That is, when someone signs up in the joomla that this person also be recorded in cimaw.com (wordpress mu), so that the same username and password you use to log into the joomla also use it to log into the wordpress.
You guys can you tell me how to do that?
Perhaps there is a wordpress plugin developed that can do that.
Thanks for your time.
