For information on how to configure this type of compound authentication control, please see: https://kb.isc.org/article/AA-00723/0/Using-Access-Control-Lists-ACLs-with-both-addresses-and-keys.html This issue has been addressed in the following products: Red Hat Enterprise Linux 7 Via RHSA-2017:1680 https://access.redhat.com/errata/RHSA-2017:1680 This issue has been addressed in the following products: Red Hat Enterprise Linux 6 Via RHSA-2017:1679 https://access.redhat.com/errata/RHSA-2017:1679 |
