Dear fellow Selinux experts,
I have encountered this before, apparently it has not gone away. Running Fedora 11 Beta. I have a small crontab file that will shutdown the machine at 4:15 pm :
[students@antonio-fedora-x86-64 ~]$ crontab -l
# min hour day-of-month month day-of-week command
15 16 * * 1-5 /usr/bin/poweroff>/dev/null 2>&1
Seatroubleshooter comes up and gives me the following:
In the other machine running rawhide I can't even access crontab -l, it tells me that I cannot do anything I have no authorizations :(
Summary:
SELinux is preventing crontab (admin_crontab_t) "read write" unconfined_t.
Detailed Description:
SELinux denied access requested by crontab. It is not expected that this access
is required by crontab 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.

I tried everything you described and it worked fine. THe
unconfined_t:unix_stream_socket is coming from the leaked file
descriptor in Konsole, I believe.
