>Summary
>    SELinux is preventing /usr/sbin/smbd (smbd_t) "read write" access to ptmx
>    (ptmx_t).
>
>Detailed Description
>    SELinux denied access requested by /usr/sbin/smbd. It is not expected that
>    this access is required by /usr/sbin/smbd 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.
>    Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this
>    package.
>
>Allowing Access
>    Sometimes labeling problems can cause SELinux denials.  You could try to
>    restore the default system file context for ptmx, restorecon -v ptmx. There
>    is currently no automatic way to allow this access. Instead, you can
>    generate a local policy module to allow this access - see
>    http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 - or you can
>    disable SELinux protection entirely for the application. Disabling SELinux
>    protection is not recommended. Please file a
>    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.
>    Changing the "smbd_disable_trans" boolean to true will disable SELinux
>    protection this application: "setsebool -P smbd_disable_trans=1."
>
>    The following command will allow this access:
>    setsebool -P smbd_disable_trans=1
