Just a quick note on an issue we discovered lately.
An Apple iPhone was unable to synchronise with the Traveler server. The only error message we got was 403 FORBIDDEN (Access not allowed even with authorization) in the Domlog.nsf.
Issue tell traveler security status username on the domino console. This will result with a listing of all devices registered to a user and their security status. In this particular case the security approval was pending for the iPhone but the device was not listed in the LotusTraveler.nsf.
Issue tell traveler security approval approve deviceID username. This will approve the pending device approval and re-add the device to the LotusTraveler.nsf.
