    SSH: Ignore the default_domain_suffix
    
    https://fedorahosted.org/sssd/ticket/2609
    
    In a trust setup, hosts are normally only stored on the IPA server. The
    default_domain_suffix option is only recommended for the IPA-AD trust
    scenario as well. Therefore we should ignore this option in the SSH
    provider.
