Hello All, I've managed to "inherit" a calendarserver running under Debian, which claims to be at version 1.2.dfsg-8 according to dpkg. I'm having several problems. Recently several of my users (who run thunderbird with lightning) are seeing the above message (in the subject) in their clients. Some are using Kerberos, some not. Thunderbird is less than helpful in logging this, there's no log of what the error is, and in fact the same error would probably be displayed with a network outage or a calenderserver problem. Since I'm using SSL, tcpdumping is not more helpful. The error.log seems to be a whole lot of useless information, most of which looks like this: OPTIONS /principals/locations/ HTTP/1.1 OPTIONS /principals/locations/ HTTP/1.1 PROPFIND /principals/locations/ HTTP/1.1 PROPFIND /principals/locations/ HTTP/1.1 REPORT /principals/ HTTP/1.1 REPORT /principals/ HTTP/1.1 REQUEST 1: If possible, I'd like to turn the above off, and make it so the error log only shows actual errors instead of every problem. REQUEST 2: How do I chase down the error in the subject line? I'm also seeing some of this: 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' 'No principal found for directory record: None' And in my previous error logs, some of this: error.log.29:2009-09-09 11:29:44-0700 [-] [caldav-8443] [-] 401 response while getting property: ('DAV:', 'current-user-privilege-set') error.log.29:2009-09-09 11:29:44-0700 [-] [caldav-8443] [-] "Error reading property ('DAV:', 'current-user-privilege-set') for resource /calendars/__uids__/c693cce5-6cf6-50cf-9e52-420697079769/calendar/: <StatusResponse 401 Access denied while reading property {DAV:}current-user-privilege-set.>" error.log.29:2009-09-09 11:29:44-0700 [-] [caldav-8443] [-] 401 response while getting property: ('DAV:', 'current-user-privilege-set') error.log.29:2009-09-09 11:29:45-0700 [-] [caldav-8443] [-] "Error reading property ('DAV:', 'current-user-privilege-set') for resource /calendars/__uids__/c693cce5-6cf6-50cf-9e52-420697079769/dropbox/: <StatusResponse 401 Access denied while reading property {DAV:}current-user-privilege-set.>" error.log.29:2009-09-09 11:29:45-0700 [-] [caldav-8443] [-] 401 response while getting property: ('DAV:', 'current-user-privilege-set') error.log.29:2009-09-09 11:29:45-0700 [-] [caldav-8443] [-] "Error reading property ('DAV:', 'current-user-privilege-set') for resource /calendars/__uids__/c693cce5-6cf6-50cf-9e52-420697079769/notifications/: <StatusResponse 401 Access denied while reading property {DAV:}current-user-privilege-set.>" (note there's no IP address there). Finally, running the following command reveals an ALARMING number of things that should in my mind either be populated or should not be there, including: root@cal:/var/spool# find /var/spool/caldavd -type d -empty -print | grep -v uids /var/spool/caldavd/principals/users /var/spool/caldavd/principals/groups /var/spool/caldavd/principals/sudoers /var/spool/caldavd/principals/locations /var/spool/caldavd/principals/resources /var/spool/caldavd/calendars/users /var/spool/caldavd/calendars/groups /var/spool/caldavd/calendars/locations /var/spool/caldavd/calendars/resources (and a couple dozen empty "uids" folders as well). Is this normal? -Dan Mahoney -- --------Dan Mahoney-------- Techie, Sysadmin, WebGeek Gushi on efnet/undernet IRC ICQ: 13735144 AIM: LarpGM Site: http://www.gushi.org ---------------------------
