Did you compile neon against openssl or the default internal ssl? I used 
against openssl.
Make sure you have the rootca from the exchange server in /etc/ssl/certs

The message/warning looks like the Exchange server expects a kerberos 
authentication. I have no experience with the EWS calendar module and 
using kerberos to authenticate.

Hope this info helps.

Michel.
