Description Braden McDaniel 2013-04-14 21:04:18 UTC
Description of problem:
Not sure if it's related to this particular issue; but I have dovecot configured to get user information from LDAP and use Kerberos for authentication.
SELinux is preventing /usr/libexec/dovecot/auth from 'read' accesses on the file /etc/selinux/targeted/contexts/files/file_contexts.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that auth should be allowed read access on the file_contexts file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep auth /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
