I'm using IMAP resources for contacts, my calendar etc. for quite a  
while now, and it works fine. You don't need kolab for this!

Let me describe my setup, so you can check whether this might be a  
solution you can use. It's a rather lengthy description, but if you  
get it working, it's really cool. I share the same address book,  
calendar etc. between all my kmail installations anywhere in the world  
and it works like a charm. I've never had any problems like data loss.  
The latter occurred frequently when sharing my address book via ssh  
(Network address book).

* I use an online IMAP account for my regular email

* I have configured a dIMAP account for the same user and server as  
the online IMAP account

* The dIMAP account does only subscribe to the groupware folders  
(contacts calendar etc.)

* The online imap account does not subscribe to the groupware folders  
(_local_ subscription to all email folders)

* In Configure Kontact -> Misc -> Groupware I've enabled the IMAP  
groupware functionality and I've set the "Resource folders are  
subfolders of" to the dIMAP account. In addition I've enabled "hide  
groupware folders" and "only show groupware folders for this account"

There is a wizard called 'kolabwizard' that can setup accounts just  
like this. However there are some quirks (not only related to  
kolabwizard:

* I was unable to supply the full server details (SSL and port) to  
kolabwizard. Upon opening kontact, a connection attempt was made once  
I wanted to enter the correct server details and of course that was  
bound to fail . This screws up the groupware config, because the  
correct folders cannot be found.

* kolabwizard tried to create the groupware folders as subfolders of  
my inbox, which doesn't work for me (either emails or subfolders in a  
folder). Creating the groupware folders as top level folders didn't  
work for me (see below), so I created a new folder called 'groupware'  
and all groupware folders are subfolders of this 'groupware' folder.

* If "hide groupware folders" is enabled, the dIMAP account will not  
show up at all in the server pane. I was a bit confused by this the  
first few times I tried to setup the IMAP resource since folder  
subscriptions can only be changed when the account is visible in the  
server pane.

* Now to the subscription business. There are two types of  
subscriptions. "Local subscriptions" and "Subscriptions" (I'll call  
them global subscriptions).
- In my setup the dIMAP account is configured to show both locally and  
globally subscribed folders and the groupware folders are the only  
ones that are globally subscribed to.
- The IMAP account only shows locally subscribed folders which are all  
my email folders.
- Above config should in principle hide the groupware folders in the  
IMAP account, however locally unsubscribing worked only when the  
groupware folders were not top level folders. This might have  
something to do with the imap server I'm using, but I'm not sure.
- When I wanted to unsubscribe all email folders from the dIMAP  
account, kmail started downloading all my emails from all folders.  
AAAARRRGGHHH - to avoid this I'm using an online IMAP account in the  
first place. I'm not sure I've ever found a way around that, except  
that I've deleted all the downloaded stuff in  
.kde/share/apps/kmail/dimap/.XXXXXXX.directory and after that kmail  
doesn't try to download the unwanted stuff again.
- if you add a new folder, it my automatically become subscribed to  
for the dIMAP account.

* Since the IMAP protocol doesn't support access from more than one client at
a time, don't activate the regular mail check for the dIMAP account.  
You will still get error messages from time to time from either the  
IMAP or the dIMAP account saying that the connection to the server is  
broken. This has been mostly harmless, except that once or twice a  
week I have to restart kontact because the IMAP account gets stuck.

I've posted a few of the details already in a thread from August 2007  
where Ingo and Volker were trying to help me to get the local  
subscription working.

Hope that helps.

Cheers,

Andreas
