For some unknown reason CalendarServer, running latest trunk version on FreeBSD 7, was hanging on startup. So I checked out release 1.3 and at least the server will start up again. Now I can browse collections with a web browser. But creating usable calendars continues to be problematic. Sunbird will let me specify a calendar on the server, without complaining, but if I try to write to it, I get a "MODIFICATION_FAILED" message. I have configured a very basic accounts.xml file with 4 users and 2 groups. No GUIDs in the XML file. Here are the server logs, with a couple of ##comments inserted. When I restart Sunbird, I don't get any error messages, the server notes that it has found my calendars, etc. Any help is much appreciated! I have been trying to get this work for quite a while now. Two asides: 1) is installing on an OS X box (vs. FreeBSD) likely to be smoother? 2) version 1.3 does not seem to be built with memcached support? ##startup 2008-12-09 15:16:26-0800 [-] Log opened. 2008-12-09 15:16:26-0800 [-] twistd 2.5.0+rUnknown (/usr/local/bin/ python 2.5.2) starting up 2008-12-09 15:16:26-0800 [-] reactor class: <class 'twisted.internet.selectreactor.SelectReactor'> 2008-12-09 15:16:26-0800 [-] Could not autodetect number of CPUs: 2008-12-09 15:16:26-0800 [-] getNCPU not supported on freebsd7 2008-12-09 15:16:26-0800 [-] twistedcaldav.logging.AMPLoggingFactory starting on "'logs/caldavd.sock'" 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] Log opened. 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] twistd 2.5.0+rUnknown (/usr/local/bin/python 2.5.2) starting up 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] reactor class: <class 'twisted.internet.selectreactor.SelectReactor'> 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Configuring directory service of type: twistedcaldav.directory.xmlfile.XMLDirectoryService 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Configuring SudoDirectoryService with file: conf/sudoers.plist 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Setting up document root at: twistedcaldav/test/data/ 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Setting up principal collection: <class 'twistedcaldav.directory.principal.DirectoryPrincipalProvisioningResourc e'> 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Setting up calendar collection: <class 'twistedcaldav.static.CalendarHomeProvisioningFile'> 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Setting up root resource: <class 'twistedcaldav.root.RootResource'> 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Setting up default ACEs on root resource 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] Setting up AdminPrincipals 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] Setting root ACL 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Setting up Timezone Cache 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Configuring authentication for realm: Live Oak 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Setting up scheme: kerberos 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Kerberos support not available 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Setting up scheme: digest 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Setting up scheme: basic 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] Configuring authentication wrapper 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] Setting up service 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Configuring log observer: <twistedcaldav.logging.AMPCommonAccessLoggingObserver object at 0x290ce56c> 2008-12-09 15:16:27-0800 [-] [caldav-8008] [startup] Adding server at 192.168.1.61:8008 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] twisted.web2.channel.http.HTTPFactory starting on 8008 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] Starting factory <twisted.web2.channel.http.HTTPFactory instance at 0x290ce60c> 2008-12-09 15:16:27-0800 [twistedcaldav.logging.AMPLoggingFactory] AMPLoggingProtocol connection established (HOST:UNIXSocket('logs/ caldavd.sock') PEER:UNIXSocket('')) 2008-12-09 15:16:27-0800 [-] [caldav-8008] [-] AMP connection established (HOST:UNIXSocket(None) PEER:UNIXSocket('logs/caldavd.sock')) ##adding new calendar in Sunbird for group admins;
