    Bug Description: setup-ds-admin.pl does not correctly set the admin server ip address
    Reviewed by: nkinder (Thanks!)
    Fix Description: If the admin server advertises its IP address in its cn=config nsServerAddress, the console will attempt to use the address instead of hostname (which will break https, btw).  If the address is set to 0.0.0.0, clients cannot use this, so must fall back on the hostname.
    Platforms tested: RHEL5
