title: Getting the Google Identification Number
body: <p>For users in a Google domain, there's a property called <code>gidNumber</code>. The only way I know of how I can access this id is by connecting to the Google Ldap. When I do a query in Google Admin Directory, I cannot find this property. Are there other methods to accessing the <code>gidNumber</code> other than via ldap?</p>
