Description TR Bentley 2009-12-21 22:04:21 UTC
Summary:

SELinux is preventing /usr/libexec/kde4/kdm_greet "rename" access on
3830d5c3ddfd5cd38a049b759396e72e-x86-64.cache-2.NEW.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by kdm_greet. It is not expected that this
access is required by kdm_greet 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) Please file a bug
report.

You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
