such a feature will be included in their next version and they dont have a release date yet
"Such feature", meaning, the feature which JFusion calls "dual login"?
Where, logging in at one J! site yields active session on other J! site(s)?
As described here?http://www.jfusion.org/index.php/forums ... 650#p27566
If that's what you are talking about, then, the situation appears to be this:
Only one of the J! sites can provide the dual login. The other J! sites can be logged-in-to, FROM that one, but none of the other sites can provide login TO any other.
("Dual" login seems to be a mis-nomer, in cases where your sites number more than 2. The feature clearly is intended for an arbitrarily great number of sites.)
The JFusion 2 release apparently will permit all sites to provide dual-login into the other J! sites. But, as you noted, the current 1.2 version only lets you configure one J! site which provides dual-login into other J! sites.
So, as long as persons on any of the sites use the login on the site which does provide dual login, instead of logging-in directly at one of the non-dual-login sites, then you will achieve "single sign on" at all sites.
However, there do appear to be a few options for making this use-case work today.
I intend to experiment with both of the following:
(A) simply configuring the login links on each site so that they each point to the proper dual-enabled site's login form. Hopefully using an existing "login redirector" extension should complete the round-trip so logged-in users wind up back on the site where they started. If this all succeeds, then the users should be able to move among all the sites without logging in again, because they logged in on the dual-enabled one in the first place. I believe this can be set up in a way which is transparent to the user.
(B) using an "include" type of extension (specifically: "Include Component" or "Component As Content"), to include the dual-enabled site's login form right on the other sites' pages. If this works, then the users will get the dual-enabled login session without actually leaving the site they're on, and again, because they would have logged in at the dual-enabled site, they should be able to move among all the sites without logging in again.
...and I'll be glad to report back here about my experiences.
If successful, it will be a model for how to achieve multi-site single-sign-on using today's JFusion 1.2, without waiting for the JFusion 2 enhancement.
