This mod requires a bit of advanced configuration; I will do my best to provide a thorough installation tutorial. You cannot just install this mod - you must configure your domains and sub-domains on the server. The mod does not configure this for you - it configures the re-direction features.

I looked through this code... is there any reason it wouldn't work on 3.8? It installed fine but I don't have other domains to test this yet.

It actually could work - we ported it from a 3.8 mod; added some new features (4.0 facebook / universal login) and tested on 4.0 environment. So, it could potentially work just fine on 3.8 as well.

Thanks, that's what I'm thinking too... If I can ever test it on 3.8 I'll let you know.

They should get their money for multiple domains, it isn't stupid at all.

Dont rain on this, let's be happy we finally have it. If you can't afford it, don't use it.

Please do please, I have been for years looking for something like this but the more I look the more I dont have a clue how to get it to work.

I will like to have 2 forums in the same domain using a sub-domain. but no clue how to do it

Thanks, will wait for the tuto :):up:

Hello!
Although I have my doubts, if you did this hack will be by something.
I also wait for a good tutorial

I will buy me a new License for vB, now I ask, Do i need to install vB on a new database or just use the same database I currently using.

There have been many attempts over the years to achieve a single login system for users over different domains with vb installs but each one of them have had issues, limitations or just simply don't work.

I have tried them all as I have a desperate need for this but my users are sick of me trying something that seemed to work in testing but ended up not working in the end and it always effects users logins causing heartache to them so I am reluctant to try yet again but I really need this.

So can someone tell me will this work if I had:
mydomain.com
mydomain.co.uk
mydomain.us
mydomain.com.au

The domains are hosted on different servers in different countries

If a user registers/logs in at any one of the domains that they are registered/logged in across all mydomains at the same time?

One solution I tried a couple of years ago sort of worked but the time it took for a user to login took a considerable amount of time so performance was a big issue...is there a performance hit with this across say 6 domains?

I really hope this one finally works as I am right in the middle of opening new sites using Xenforo instead of vBulletin but a single login mod is the most important to me.

Thanks for your help!

FYI while it does install on 3.8 it causes a fatal error on the login/logout screen due to some 4.0 php code (VB Class?) so it will need SOME edit to work on 3.8.x.
