Description Philipp Hahn

univention-dhcp does not start when the DNS server is not yet available. In that case the /etc/init.d/univention-dhcp # test_config() fails to resolve the LDAP server and aborts switching RUNSV to running. This is logged in /var/log/univention/dhcp.log:
> ... POLICY ( ERROR ) : Failed to get namingContexts: Can't contact LDAP server

I'm able to re-product this by adding a "sleep 10" to "/etc/runit/univention-bind-samba4/run" before BIND9 is started. It does not trigger always.
