13 domains 1 codebase shared login

This question is a bit similar to what has been asked here before but my use case is a bit different.

I have 13 Drupal 7 sites that share the source code. 12 of them run the same modules / settings but look slightly different. At the moment I use 13 databases.

I have about 50 users on each site and each user has some nodes.
Every site has its own taxonomy terms but the vocabularies are mostly named similar.

My goal is to let users from site A login into site B without filling in their profile again.
I have some custom modules running that alter the user profile fields.

Single/Simple Log On für über 50 Websites

Hallo liebe Drupal Group,

Ich bin einer der Admins vom deutschen Gamingnetzwerk Globalgameport. Wir haben über 50 Fansites zu Spielen und mehr.
Alle Seiten werden unter ihrem eigenen Top Level Domain gehostet.
Derzeit wollen wir gerne nach Drupal umziehen. Dafür wünschen wir uns einen Single Sign On.
Da wegen der Anti XSS Funktionen in den Modernen Browsern leier keine Cookies für fremde Domains gesetzt werden können, stellt sich die Frage wie man ein Sigle oder auch Simple Log on realisieren kann.

Derzeit teste ich eineige Versuche mit den Modulen, openid_provider und openid_sso

Summary: Omniauth - OpenID Single Sign-On for Drupal

Hello,

I'm just trying to get all information, spread out in different nodes and comments, together into one single post:

We implemented a OpenID single sign on solution for some of our clients (we call it Omniauth). It's based on Development Seeds great work on an OpenID Single Sign on solution for Drupal. Besides general improvement, instead of using feeds, foaf and PubSubHubbub to synchronize user information we used OpenID's own update_url (http://openid.net/specs/openid-attribute-exchange-1_0.html#fetch_request) and store_request (http://openid.net/specs/openid-attribute-exchange-1_0.html#store_request) to share user information between sites.

Omniauth includes the modules that are necessary, exported configuration into Features and installation profiles for both provider and relying parties.

I made a screencast to allow you to understand easier how to set up Omniauth and it's provided functionality at this moment: http://vimeo.com/xamanu/omniauth-drupal-openid-single-sign-on-solution

Logging in with Shibboleth doesn't fire the "User Login" Event?

In my installation the users login with Shibboleth [1], but the rule [2] I've set up to be executed on "User has logged in" event, isn't executed.

On the other hand, when I login as administrator through the normal Drupal way, the rule is executed.

Does this mean that the external login event isn't handled at all?

Is there a way to overcome this?

Single Sign On

I am wondering if anybody in the group has had a module that they have used that does a single sign-on across multiple domains on multiple servers. Not expecting the hard lifting to be done by others; just a point in the right direction.
