Hi all, after upgrading to Kolab 2.2.3, I see exactly every 15 minutes the following message in the slapd logs: <debug> slapd[15810]: do_search: invalid dn (k=kolab,) Any idea what goes wrong here? Related to that, in slapd.conf I have the setting "loglevel none". Why do I see the debug messages? Thanks, Albrecht.
