Future IDP Support

Currently the only identity providers supported by GITKit are Google Mail, Hotmail, Yahoo Mail, AOL Mail and Google Apps.  GITkit will include support for other identity providers in the future that have been certified against the "trusted email" and "email hosting" profiles

If you want to use another IDP, it is possible to configure the GITKit JS account chooser widget to rely on GITKit for some IDPs and connect directly to your server for other IDPs (see article).
