Using PolicyKit-0.8-3.fc10.i386 and selinux-policy-targeted-3.3.1-55.fc9.noarch

Summary:

SELinux is preventing polkitd (polkit_t) "setgid" to <Unknown> (polkit_t).

Detailed Description:

SELinux denied access requested by polkitd. It is not expected that this access
is required by polkitd 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.

Comment 1 Daniel Walsh 2008-07-07 12:23:07 EDT
Fixed in rawhide policy.  Please update your policy.
Comment 2 Bastien Nocera 2008-07-07 12:44:10 EDT
This is also a problem in F9, unfortunately.
Comment 3 Daniel Walsh 2008-07-07 13:48:43 EDT
It should be fixed there also in the latest policy.
