Public bug reported:

Binary package hint: apparmor

I've created the following profile for my application (using logprof tool):
------------------------------------------------------
# Last Modified: Thu May 19 14:09:16 2011
#include <tunables/global>

/tmp/test_lin_new.x flags=(complain) {
  #include <abstractions/apache2-common>
  #include <abstractions/base>
  #include <abstractions/nis>

  capability net_bind_service,
}
-----------------------------------------------------

As I understand it should be able to provide access for application to
bind on ports less than 1024, but it does not work.

Man page also confirms this:

> man capabilities
CAP_NET_BIND_SERVICE
              Bind a socket to Internet domain privileged ports (port numbers 
less than 1024).

But application cannot bind to port less 1024.
