Hi, I've set up Cyrus-imapd v3.4.2 on Ubuntu 20.04. The IMAP portion is working perfectly, but I am having trouble getting CalDAV Freebusy to work with both Apple Calendar.app and Thunderbird (native and TBSync). In either case, the CalDAV clients don't get the freebusy info for invitees, even though there are conflicting appointments on their schedule.
I included below a copy of my imapd.conf file, as well as output from cyradm showing the 2 mailboxes for user1 and user2, as well as the ACL #9 for "anyone" on the #calendars sub-folder, as per documentation. Any advice would be appreciated! admins: cyrus allowanonymouslogin: no allowplaintext: yes altnamespace: yes autocreate_inbox_folders: sent|drafts|spam|templates autocreate_quota: 0 caldav_allowattach: 1 caldav_allowcalendaradmin: 1 caldav_allowscheduling: on caldav_create_attach: 1 caldav_create_default: 1 caldav_create_sched: 1 calendar_component_set: VEVENT VTODO VJOURNAL VFREEBUSY VAVAILABILITY VPOLL calendar_user_address_set: domain.tld carddav_allowaddressbookadmin: 1 chatty: 1 configdirectory: /var/lib/cyrus debug: 1 defaultdomain: server.domain.tld defaultpartition: default hashimapspool: true httpmodules: caldav carddav freebusy ischedule idlesocket: /run/cyrus/socket/idle lmtp_downcase_rcpt: yes lmtpsocket: /run/cyrus/socket/lmtp loginrealms: domain.tld mboxname_lockpath: /run/cyrus/lock notifysocket: /run/cyrus/socket/notify partition-default: /var/spool/cyrus/mail popminpoll: 1 proc_path: /run/cyrus/proc sasl_auto_transition: no sasl_mech_list: PLAIN sasl_pwcheck_method: auxprop sievedir: /var/spool/sieve sieveusehomedir: false syslog_prefix: cyrus tls_client_ca_dir: /opt/ssl/ca_dir tls_server_cert: /opt/ssl/domain.tld.crt tls_server_key: /opt/ssl/domain.tld.key tls_session_timeout: 1440 tls_versions: tls1_2 tls1_3 umask: 077 unixhierarchysep: no virtdomains: on cyradm --user=cyrus localhost Password: localhost> lm user.user1.#addressbooks.defa...@domain.tld (\HasNoChildren) user.user1.#addressbo...@domain.tld (\HasNoChildren) user.user1.#calendars.attachme...@domain.tld (\HasNoChildren) user.user1.#calendars.defa...@domain.tld (\HasNoChildren) user.user1.#calendars.in...@domain.tld (\HasNoChildren) user.user1.#calendars.out...@domain.tld (\HasNoChildren) user.user1.#calend...@domain.tld (\HasNoChildren) user.user1.#notificati...@domain.tld (\HasNoChildren) user.user1.out...@domain.tld (\HasNoChildren) user.user1.tr...@domain.tld (\HasNoChildren) user.us...@domain.tld (\HasNoChildren) user.user2.#addressbooks.defa...@domain.tld (\HasNoChildren) user.user2.#addressbo...@domain.tld (\HasNoChildren) user.user2.#calendars.attachme...@domain.tld (\HasNoChildren) user.user2.#calendars.defa...@domain.tld (\HasNoChildren) user.user2.#calendars.in...@domain.tld (\HasNoChildren) user.user2.#calendars.out...@domain.tld (\HasNoChildren) user.user2.#calend...@domain.tld (\HasNoChildren) user.user2.#notificati...@domain.tld (\HasNoChildren) user.user2.out...@domain.tld (\HasNoChildren) user.user2.tr...@domain.tld (\HasNoChildren) user.us...@domain.tld (\HasNoChildren) localhost> lam user.user1.#calend...@domain.tld us...@domain.tld lrswipkxtecdan9 anyone 9 localhost> lam user.user2.#calend...@domain.tld us...@domain.tld lrswipkxtecdan9 anyone 9 Thanks, Peter Alexander ------------------------------------------ Cyrus: Info Permalink: https://cyrus.topicbox.com/groups/info/T2af76677834d90f9-Mbb04bf9688249bebe1485cbb Delivery options: https://cyrus.topicbox.com/groups/info/subscription
