Description Dmitri Pal 2010-10-06 14:31:40 UTC

Summary:

SELinux is preventing /usr/sbin/certmonger "search" access on /etc/httpd.

Detailed Description:

SELinux denied access requested by certmonger. It is not expected that this
access is required by certmonger 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.

Comment 1 Daniel Walsh 2010-10-06 14:51:44 UTC

Are certs stored under /etc/httpd?

Yes I asked Nalin on IRC and he told me to add it, and we will add other directories where we know the certs can be stored.
