Project Goals:

• Email,  Address-Books(s),  Calendar
  

• 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
  

2. SoGO Groupware
• Uses OpenLDAP
  
3. Zimbra Collaboration Suite
• Large monolithic app ?

Possible Solution 1:

• IMAP + OpenLDAP + CalDAV?
• OpenLDAP configuation difficult
  uses Backend LDAP, not config files.
  

• 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
• InetOrgPerson +  ?
• mozillaAbPersonAlpha
  

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

• Uses mostly open-source apps:
  
• PostgreSQL DB
  
  
• Postfix MTA
  
  
• OpenLDAP
  
  
• Courier IMAP
  
  
• Custom server, Funambol, Thunderbird + Lightning 

Possible Solution 2: Sogo

• SoGO Groupware

• 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

Possible Solution 2: Sogo

• SoGo Demo
  
  
• Comments from eval mid 2010.
