Integrating Funambol with CalDAV and LDAP
1 like1,471 views
The document discusses integrating Funambol with CalDAV and LDAP to synchronize calendar events across devices. It describes how Babel uses Funambol and CalDAV to integrate calendar syncing with its LDAP authentication system. It also discusses issues with calendar data formats and the Connector Testing Framework used to test calendar syncing functionality.

Integrating Funambol with CalDAV and LDAP
- 1. Connecting the Enterprise Integrating Funambol with CalDAV and LDAP Roberto Polli - rpolli@babel.it
- 2. Overview Why Babel chose Funambol Integrating LDAP and CalDAV Insight CalDAV Connector: iCalendar and interoperability issues Connector Testing Framework: speed up RFC compliance Open issues - rpolli@babel.it
- 3. Italians do it better ;) Babel mission: provide large mail infrastructure entirely based on independent RFC modules SMTP, IMAP, LDAP, CalDAV (RFC4791), iCalendar(RFC2445) SyncML Why Funambol? Italians do it opensource! - rpolli@babel.it
- 4. LDAP: just for Fun Babel authentication system is based on LDAP, with user data on FedoraDS Our first experience was about writing: LdapConnector support for FedoraDS LdapUserProvisioningOfficer ..and it was fun :) Then we needed to sync Calendar events - rpolli@babel.it
- 5. CalDAV is a calendar access protocol based on webdav/http and iCalendar (RFC2445) defined by RFC4791 one event – one .ics file accessible by http support queries (by time-range, location, etc.) various implementations (Bedework, Google, Apple, OSAF, ...) CalDAV: open your agenda! - rpolli@babel.it
- 6. Internet grew with email connecting people. CalDAV makes people meet share freebusy times organize meetings schedule tasks These flows need to be interoperable and mobilized , hopefully converging to iCalendar Why CalDAV Connector - rpolli@babel.it
- 7. Mobiles store events in vcal-1.0 (vcs) vendor-specific attributes limited interoperability iCalendar (ics) attempts to unify these things Converting ics to vcs and back is not easy ics to vcs causes data loss ics recurrence rules are complex to sync to vcs round-trip item conversion Funambol support of RFC2445 Open issues - rpolli@babel.it

- 10. Connector Testing Framework FCTF enables round-trip event testing no need to deploy fast debugging collect data from mobile (ics,vcs,..) scripting use cases Still to do Pipelines – normalize item from/to mobiles logging Add on server, update on mobile #!/bin/bash first sync add event on server sync modify event on client sync check event on server - rpolli@babel.it
- 11. Writing CalDAVConnector lead us to: improve and maintain CalDAV4j bugfix Funambol & Bedework Once more writing OSS is like sowing good seeds ;) Sowing the seeds of love DaPino - http://dapino-colada.nl - rpolli@babel.it
- 12. Conclusions Support for RFC2445 is a primary target for Funambol achieve interoperability offline sync solution for desktop Improving FCTF is a great way to achieve it - rpolli@babel.it
