Openfire clustering

I am facing a problem using the open fire clustering plugin.

Where can I find the enterprise.jar (clustering plugin) ?

The enterprise.jar file is missing in the plugin webpage (http://www.igniterealtime.org/projects/openfire/plugins.jsp)

I googled and found the plugin at http://download.huihoo.com/openfire/plugins/

I used the plugin against 3.6.4 version of openfire. The server reports of a licensing issue.

“Clustering license is not valid. You need to update your license to enable clustering.”

Is the clustering solution still available ? I could find some threads in the forum saying that the clustering solution is no longer available.

If clustering is available, do I need a separate license ? how do I get the license ? Is there a beta license available to try out the feature.

Please help.

Yes openfire clustering plugin no longer available.

But some person making effort for clustering see this http://www.igniterealtime.org/community/thread/38766
