Description horner 2009-12-15 19:04:52 UTC
Summary:

SELinux is preventing /usr/libexec/dovecot/deliver "search" access on /var/log.

Detailed Description:

[deliver has a permissive type (dovecot_deliver_t). This access was not denied.]

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

Comment 1 Daniel Walsh 2009-12-15 19:42:31 UTC
Did you change the configuration of dovecot some how?

Comment 2 Daniel Walsh 2009-12-23 17:50:32 UTC

You can add these rules for now using

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