SELinux Error Configuring Samba

Hey folks,
I'm trying to setup Samba on this F10 server. To do so, I am trying to
run a program out of the "System" menu.
Menu path:
System -> Administration -> Samba
The program does not run. Instead, SELinux comes up with the following
error.
--- Begin SELinux Alert ---
Summary:
SELinux is preventing polkitd (polkit_t) "search" to ./32587
(unconfined_notrans_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:
Sometimes labeling problems can cause SELinux denials. You could try to
restore
the default system file context for ./32587,
restorecon -v './32587'
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 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.

--- End SELinux Alert ---
The resolution instructions do not work as listed above. Basically, I
don't think restorecon can find the directory - I think its made when
you try to run the program. Each time you run it, you get a separate
SELinux error with a different numbered directory at the end of the
command.
Thoughts?
