Bug 543416

Summary:

SELinux is preventing nscd (nscd_t) "write" rpm_script_t.

Detailed Description:

[nscd has a permissive type (nscd_t). This access was not denied.]

SELinux denied access requested by nscd. It is not expected that this access is
required by nscd and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.
