Comments: | By: Matt Jordan (mjordan) 2012-05-01 08:05:11.007-0500 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. |
