Description Alvin Thompson 2007-06-03 18:30:56 UTC
Summary
    SELinux is preventing /bin/cat (logwatch_t) "read" to log.smbd
    (samba_share_t).

Detailed Description
    SELinux denied access requested by /bin/cat. It is not expected that this
    access is required by /bin/cat 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
    Sometimes labeling problems can cause SELinux denials.  You could try to
    restore the default system file context for log.smbd, restorecon -v log.smbd
    If this does not work, 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 altogether. Disabling SELinux protection is
    not recommended. Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

SELinux is preventing 0logwatch (logwatch_t) "getattr" to
/var/log/samba/log.europa (samba_share_t).
