Yes, this is the thing i did.
Downloading the new Connector in the admin Console after updating to version 5.0.5.
But if i install the connector and look for the properties of the pkg file, i see that!!!

And here you can see, that the Version of connector is still 5.0.2!!!
Why??
And in Connections settings of Zimbra iSync connector i see the version 5.0.2, too.
