I am using asterisk 184.108.40.206 and compile all modules related to calendar.
neon version is 0.29.6. OS is ubuntu 11.10.
I configured ical for zimbra, caldav for google mail and ews for exchange 2010 calendar.
ical and caldav setup working fine and i am getting my calendar events perfectly. But for exchange 2010 calendar i am getting following error.
"Unable to communicate with Exchange Web Service at 'https://ex1.domain.com/EWS/Exchange.asmx': Could not authenticate to server: ignored NTLM challenge, GSSAPI authentication error: Unspecified GSS failure. Minor code may provide more information: Credentials cache file '/tmp/krb5cc_0' not found"
my calendar.conf is as follows
type = ews ; type of calendar--currently supported: ical, caldav, exchange, or ews
url = https://ex1.domain.com/EWS/Exchange.asmx ; URL to MS Exchange EWS
user = firstname.lastname@example.org ; Exchange username
secret = xxxxxx ; Exchange password
refresh = 10 ; refresh calendar every n minutes
timeframe = 20
calendar show status command shows following output
Calendar Type Status
-------- ---- ------
calendar3 ews free

This appears to be a configuration issue with your authentication mechanism with Exchange, and is not a problem with the res_calendar_ews module. Some quick googling of the error message being returned from Exchange "ignored NTLM challenge, GSSAPI authentication error: Unspecified GSS failure" resulted in a large number of similar results from other systems. Specifically, you may want to refer to http://research.imb.uq.edu.au/~l.rathbone/ldap/gssapi.shtml.
