Google Apps restricted login

[Gautam S. Thakur]

Hi, 

My organization is using Google education app. All the students and admins have their email address ending '@mydomain.edu'. This is also used for accessing Google Education app. 

We are developing an adaptive learning platform to accompany Google Education App,  that will enable social sign-in. For this purpose, we are interested in using SocialAuth Spring MVC. However, we want to limit the access to user with email address ending '@mydomain.edu' only. (Thus other user with any other email domain are not allowed)

Do you think it is possible? If yes, any help would be appreciated. In particular, creating some sort whitelist of domains etc. and method to implement it. 

Thanks and regards,

-Gautam
