    Skip shadow checks for users w/o shadow data

    Users that are attached to a Kerberos realm do not have shadow data
    on the system. This breaks two accounts-related tasks.

    This patch cause Ansible to skip over any users that do not have
    shadow data on the system. Without this patch, the playbook fails
    with an error.
