I am using asterisk 220.127.116.11 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
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
