[Dovecot] Web-based shared calendar synchronizable with Outlook

[Samuel HAMEAU]

Hi,

I know this request is a a little off-topic but may be interesting for
dovecot users (at least i hope!)

Does anybody has already had an experience with a calendar sharing 
solution including a webcalendar and an outlook connector, "compatible" 
with dovecot ?
Today, there are many projects aiming to be a "M$ Exchange Killer" (such
as Zimbra, OBM, open-exchange, etc) but they offers a global package 
with MTA and imap server included.

I saw the page about BynariConnector 
(http://wiki.dovecot.org/HowTo/BynariConnector) but unfortunatly they do 
not provide a webmail :(
I'm afraid


What I am looking for is a shared agenda solution providing a 
webcalendar, an outlook connector and eventually a pda connector, using 
(or not) dovecot, and a corporate ldap server...

What are you guys using ?
