Bug 543013

\u0421\u0432\u043e\u0434\u043a\u0430:

SELinux is preventing /usr/sbin/nscd access to a leaked packet_socket file
descriptor.

SELinux denied access requested by the nscd command. It looks like this is
either a leaked descriptor or nscd output was redirected to a file it is not
allowed to access. Leaks usually can be ignored since SELinux is just closing
the leak and reporting the error. The application does not use the descriptor,
so it will run properly. If this is a redirection, you will not get output in
the packet_socket. You should generate a bugzilla on selinux-policy, and it will
get routed to the appropriate package. You can safely ignore this avc.

You can generate a local policy module to allow this access - see FAQ
