OK. Let's go for this path. I will upload a new kolabd that revert the
hack and upload a new libkolab-perl package which run slaptest after
changing any openldap config (this is where this fix belongs).

For the long term, how can we be sure to have write access to
cn=config? Couldn't slapd package provide a tool to query cn=config
(like ldapconfigsearch) which uses ldapsearch with proper credentials
if slapd is running and uses something else when slapd is stopped.
Similary, provide an ldapconfigmodify. Also providing ldapschemaadd,
ldapschemaremove, ... can ease the integration from other packages.

As a general note, the move to cn=config makes it possible to modify
slapd config in a Debian way but not in an easy way. I'm open to any
recommendation to make this easier.

I have seen this change long before it entered sid. So this is my
fault too (and lack of time as usual ;). And Debian has to be sometime
the distrib which push things forward.

Thanks for the hard work.
