Bug 967580

Do you use mod_authn_sasl? Or is /var/run/saslauthd mountpoint?

SELinux is preventing /usr/sbin/httpd from search access on the directory saslauthd.

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

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