User sync extensions

Bojan,
We don't do active testing with user syncing plugins, so I can't make any guarantees as to what 'currently' works or doesn't. For usersyncing in general, we'd recommend jFusion. It seems to be the most popular and well supported extension for doing what you're looking for. In the past, we've helped users overcome most, if not all, issues they've run into while trying to use jFusion... in honesty though, we haven't had a jFusion question in about 6 months, that I can remember.

In general though, JFBConnect creates 100% standard Joomla users, which should be able to be synced to other Joomla sites. However, please note:
1) This would sync just the Joomla user (their J! username and password), not necessarily their FB connect information for logging in that way on other sites.
2) You should be able to easily copy the FB/Joomla usermap stuff between sites, but jFusion (or others) likely won't do this automatically. It's a pretty easy SQL query to do so, and may be able to be inserted into a plugin for jFusion or something similar.
3) Even if the FB/Joomla usermapping information is copied, each site that Joomla is run on will need it's own FB app/secret key (if they're on different domains, at least). So, when the user first logs into a different site than the initial one they did, they'll need to approve the 'new' FB application. The logging in should be normal after that. This is not the case if the other Joomla sites are all in sub-directories or sub-domains of the original site.

Hope that helps explain. It will be complex, but it should all be do-able.

No problem for the help, it's what we do. Pretty sure JFusion has great tools for syncing across multiple Joomla sites, but could be wrong

As for the other things you mention (one domain, auto link users), sounds like you got it all figured out. You shouldn't run into too many problems, I'd guess.. but, if you do, you know where to find us!

Finally, please consider leaving a rating and review on the Joomla Extension Directory for JFBConnect, or our support. It's certainly not required, but very appreciated!

Good luck,

Bojan,
Thanks for the review. We do appreciate it. You scared me at first, but we track reviews... we know what you rated us Thanks! Can't wait to see what you wrote.

Should you need anything else, just let us know, and good luck!
Alex

Please do keep us posted! Very curious, and hope it goes well!

Thanks,
Alex

Actually, forgot to mention one other final thing... On sourcecoast.com, we actually run multiple Joomla sites (for many reasons), but it may pertain to you how we do it. For our JFBC Demo site (sourcecoast.com/jfbconnect/demo), that's it's own Joomla installation. When a user logs into that site (with Facebook), they approve the FB app and create an account. While the user isn't automatically created on 'this' site, if they later come to this site (to purchase for instance), if they hit the Login w/ FB button, their account is automatically created for them. That's because we have the "Facebook User Only" setting enabled on this site.. so, unless you need the accounts automatically created across all sites instantaneously, you could almost have the 'feeling' that they are by using the Facebook User Only option.

Hope that makes sense and possibly helps give some ideas!
Alex
