I am writing a Gmail Contextual Gadget, and in order to authenticate the user correctly on the server, i need to know their full email address ([email protected]).
I can retrieve the domain (googleapps.com) but not the username.
Using the content extractors I can get the 'To' field on the email, the only problem is if there are two users on the same domain emailed (ie [email protected] and [email protected]).
Any thoughts?
You need to implement SSO (single sign-on) within the contextual gadget. When the contextual gadget loads it passes the opensocialid of the user. You have to maintain a correlation between the user emailid and user opensocialid in your local database and do the identification by opensocialid lookup.
