/etc/init.d/slapd of net-nds/openldap package hasn't depend "provide ldap", therefore net-dns/bind (/etc/init.d/named has "after ldap" ) can start before slapd. And if bind work via ldap, then it doesn't run. Reproducible: Always Steps to Reproduce: 1.Add apache2 to default runlever. 2.Add named and slapd to default runlevel. 3.Reboot.
Fixed in 2.4.21, thanks for the heads up
