We've come up against 1 iPhone user (out of the 10 or so we are testing) that just will not work. The log files continue to show:

DEBUG [CP WSGIServer Thread-26] [DeviceInterface:690] [eventID:] [objectID:] [Server] Failed to Authenticate user <UIDHERE>

He can login to the https://server:8120 interface with his newly reset password, however his iPhone continues to fail with "Incorrect Password". We've compared his phone to the other working iPhone users, and can't find anything different.

Any suggestions on what to try for this user? Anybody else having a similar issue?
