Hello, I'm working on getting my application's digest authentication to work with calendar server. I noticed that Evolution users had, at least at one point, the same issue we're facing... https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/160190 Does Evolution currently work with calendar server + digest authentication? Specifically the error is raised in 'digest.py'. Calendar server complains that the nonce count value is more than it expected... 2008-03-30 10:46:31-0700 [-] [caldav-8008] [HTTPChannel,1,208.54.95.252] PROPFI ND /calendars/users/kervin/calendar/ HTTP/1.1 2008-03-30 10:46:31-0700 [-] [caldav-8008] [HTTPChannel,1,208.54.95.252] 'Authe ntication failed: nonce-count value out of sequence: 2 should be one more than 0 ' Can anyone shed some light on this?
