Migrating to a smart phone without Google

by lmarzke last modified Jul 12, 2011 05:10 PM
Is there a Linux friendly smart-phone collaboration alternative Gmail ?

Project Goals:

  • Email,  Address-Books(s),  Calendar
  • 113 Bridge Destruction
  • Linux, Windows, (Mac)
  • Android, iPhone
  • Target: SMB's ( 2 to 1000 users)
  • Open Source desirable if possible.

Possible Solutions:

  1. IMAP + LDAP + CalDAV ?
  • Looks good initially
rt113 Bridge Claw
  • SoGO Groupware
    • Uses OpenLDAP
  • Zimbra Collaboration Suite
    • Large monolithic app ?

     

     

     

     

     

     

     

    Possible Solution 1:

    • IMAP + OpenLDAP + CalDAV?
      • OpenLDAP configuation difficult
        uses Backend LDAP, not config files.
      crane
    • IMAP + 389Directory + CalDAV ?
      • Huge complex server !
    • CalDAV

     

     

     

     

     

     

     

    Issues with LDAP (1):

    • LDAP is complex
    • Most email clients can't write LDAP !
      • Thunderbird LDAP writing has never been fixed !

    • No standard LDAP schema

    Issues with LDAP (2):

    • Commands ldapadd, ldapmodify, ldapdelete, ldapsearch
    • Data format LDIF:  sample data
    • Add data using:

    ldapadd -f data.ldif -h 10.24.1.57 -x -W -D "uid=LMarzke,ou=People,dc=4aero,dc=com"

    Posible Solution 2: SoGO

      piling1
    • Uses mostly open-source apps:
      • PostgreSQL DB

      • Postfix MTA

      • OpenLDAP

      • Courier IMAP

      • Custom server, Funambol, Thunderbird + Lightning 

     

     

     

     

    Possible Solution 2: Sogo

    • SoGO Groupware
    • bubba
      • Custom Sync Client/Server (Funambol)
        • uses SyncML protocol

      • On Thunderbird client
        • Custom modified Lightning Calendar required for TB

    Possible Solution 2: Sogo

    • SoGo Configuration
      • /home/sogo/GNUstep/Defaults/.GNUstepDefaults

      • to modify:  sudo - sogo
        defaults read sogod
        defaults write sogod SOGoTimeZone "America/New York"

      • Changing domain from 'example.com' requires new LDAP domain+admin

      • Documentation does not cover this - must read forums, etc.

    Possible Solution 2: Sogo

     

    • System Architecture
    • sogo overview

     

    Possible Solution 2: Sogo

    • SoGo Demo

    • Comments from eval mid 2010.
      • Open Source and Paid use same release.

      • Desktop OK,  most Mobile features inop without undocumented workarounds.

      • Changing Domains  ( new LDAP domain ) not covered.

      • Lots of advanced questions with mobile, etc. not covered in docs
