        sshd-none       account pam_deny.so.1

        sshd-none       password pam_deny.so.1

       Example 2: Disabling all sevices

       The  following  example  shows how to disable all services that are not

            other           account pam_deny.so.1
            other           session pam_deny.so.1

NOTES
       The interfaces in libpam(3LIB) are MT-Safe only if each  thread  within
       the multi-threaded application uses its own PAM handle.

       This  module  is  intended to be used to either deny access to specific
       services names, or to all service names not  specified  (by  specifying
       pam_deny.so.1 as the default, "other", service stack).
