    Bug Description: Running setup-ds-admin.pl -u on replica with ldaps chokes on CA cert
    Reviewed by: nkinder (Thanks!)
    Fix Description: If the config directory LDAP url begins with ldaps, set the certdb to the existing cert directory.  NOTE that this assumes you have a valid CA cert in your cert db already, and does not allow you to change it during setup.
