I am trying to setup an iPhone for a client and when I try to verify the account on the phone, I get the following in the event logs:

Logon Failure:
       Reason:            Unknown user name or bad password
       User Name:      domain\bob
       Domain:            
       Logon Type:      3
       Logon Process:      NtLmSsp
       Authentication Package:      NTLM
       Workstation Name:      XXXX iPhone
       Caller User Name:      -
       Caller Domain:      -
       Caller Logon ID:      -
       Caller Process ID:      -
       Transited Services:      -
       Source Network Address:      -
       Source Port:      -

with an event ID of 529. I have IMAP open on the firewall and am able to telnet to it, so I think the authentication issue is the last thing holding me back. I have tried all the following variations of the user name:
domain/username
username@domain.local
username
domain/John Doe/alias

I have also logged in as the user through OWA to verify that the name and password are correct. Any help is appretiated.
