Securing NFS Describe the issue: In RHEL7 we no longer support DES for Kerberos principal keys. We should add a note to the NFS section to make the deprecation visible for customers setting up secure NFS. Suggestions for improvement: """ The version of krb5-libs shipped in Red Hat Enterprise Linux 7 does not support the usage of DES encryption keys in new deployments. There always have been compatibility issues with Microsoft Active Directory and this resurfaced again with the introduction of FAST into Kerberos’s protocol. DES is deprecated and has been left into the product only as a compatibility option (it is disabled by default in fact). """ Additional information:
