Set Google Type manually

Since Google allows you to user your own email account for google apps it's not useful to lookup the domain in the $email string variable if it's gmail.com or mail.google.com:

if( stristr($email, 'gmail.com') || stristr($email, 'mail.google.com') ) {
  $type = 'GOOGLE';
} else {
  $type = 'HOSTED';
}

If you leave this, you might have some problems with authentication.

So that's why I added a Type Selection at the Config Form to choose the Type of Account manually.
Please find attached Patch for this.
