Let me state first, this is not for production, I'm testing and there are still many things to do yet to make it completely stable. I don't want to write a full howto yet because I think it still needs alot of finishing. Here's what I've done so far.
Build a stock 7.3 server
Add and update kronolith, nag, mnemo, turba, gollem, with yum to the server from the smetest repo. I also made reference to this
http://wiki.horde.org/RHEL3PearHowTo?referrer=HowTo#Verify all of that is working.
Remark out the realm line in /home/httpd/html/horde/imp/config/servers.php. NOTE: This should be templated or added as a DB variable before ever going into production.
Add funambol to a WinXP running Outlook (2000-2003,XP)
Configure funabol from this reference:
http://wiki.horde.org/SyncHowTo?referrer=HowTo#Contacts are still not syncing but the Horde Tables need modification, I'm about to test this to see how well it works. Reference here
http://wiki.horde.org/TurbaOutlook2003?referrer=HowTo#Once all this is tested and working, I'll add funambol to a smartphone device to see how well it syncs with Horde.
I hope this helps the community. There is certainly a real need to outlook interface with a linux based server for the business communities worldwide. Now with MS Vista having calendar.tasks also built into it, theres even more a need for synchronization.
