Fix client krb5 domain mapping and DNS

Add Kerberos mapping for clients outside of server domain. Otherwise
certmonger had problems issuing the certificate. Also make sure that
client DNS records on the server are set before certmonger is started
and certificate is requested.

Based on Lars Sjostrom patch.
