when i use samba to share a folder with the following command:
net usershare add share_1 /home/dennis/Desktop/junk "" dennis:F guest_ok=y
settroubleshoot tells me:
Summary
SELinux is preventing /usr/bin/net (samba_net_t) "read" to <Unknown>
(samba_share_t).
Detailed Description
SELinux denied access requested by /usr/bin/net. It is not expected that
this access is required by /usr/bin/net 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 <Unknown>, restorecon -v
<Unknown> 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.

when selinux is in permissive mode, I can share this folder. In Enforcing mode I can not.
The following is the security contex of /var/lib/samba/usershares

Any help would be appreciated.
