You know it isn't supported. It may take heavier work than that -- I.e., make some changes to the LDAP server, then kill -9 before it checkpoints to force an unclean shutdown, then try starting slapd back up. But none of those necessarily will cause the error to show. But if you can get it to show, it definately is a problem for that Xen release.
