I recently changed my Gmil account to use two-factor authentication. I have not had any problems re-configuring any other clients or tools, on pc or mobile platforms. However, I cannot seem to get my Gmail external IMAP account to authenticate. I have created the necessary "application-specific password" but it is not accepted and testing the connection always fails.

Any ideas as to how to configure an external Gmail account which is using two-factor authentication? Running the latest 7.2 of ZCS on CentOS 5.8
