Description Ralf Oltmanns 2010-04-23 09:12:32 UTC

Zusammenfassung:

SELinux is preventing winbindd "name_connect" access .

Detaillierte Beschreibung:

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

Zugriff erlauben:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Miroslav, this is allowed in F13 policy.
