I decided to use KStandardDirs->saveLocation("cache", "ldapkio"), like http. 
On my system it's /var/tmp/kdecache-$USER/ldapkio. Any problems with this?

It's one file per resource, now using Resource::type() + "_" + 
Resource::identifier() as the file name. I think it's not worth sharing 
offline data between resources, because it should be not common using 
different resources for the same data.

The problem is that no one notified about the resource deletion (or is there 
anything for this?)
