Connect to GMail using JavaMail

[di...@nubbius.com]

Hello,

I want to connect to GMail using JavaMail 1.5.2. I have two kind of clients: for one hand, there're clients who use OAuth 2.0 2-legged (service account) and they connect to GMail and they can get the messages fine. For another hand, there're clients who use OAuth 2.0 3-legged (normal identification). I can't connect with them to GMail. 

The Java code that I'm using to connect is:

 Properties props = new Properties();
 props.put("mail.imap.ssl.enable", "true"); 
 props.put("mail.imap.sasl.enable", "true");
 props.put("mail.imap.sasl.mechanisms", "XOAUTH2");
 props.put("mail.imap.auth.login.disable", "true");
 props.put("mail.imap.auth.plain.disable", "true");
 Session session = Session.getInstance(props);
 Store store = session.getStore("imap");
 store.connect("imap.gmail.com", email, access_token);

When I try this code, my debug says:

DEBUG: setDebug: JavaMail version 1.5.2

DEBUG IMAPS: mail.imap.fetchsize: 16384

DEBUG IMAPS: mail.imap.ignorebodystructuresize: false

DEBUG IMAPS: mail.imap.statuscachetimeout: 1000

DEBUG IMAPS: SASL callback length: 1

Well, I don't know what happens but it has to be because of OAuth 2.0 because I have tried to connect to GMail without OAuth 2.0 (using email and password) and it works fine.

Any idea?

Are all client accounts failing the 3-legged OAuth, or are there some accounts that work properly and some that do not? Can you construct a simple test case that fails for you, yet you expect it to work? Finally, what scope did you request when collecting the access token?

Did you try using username/password with the same accounts that are failing the 3-legged OAuth login?
