I think you're confusing things. This doesn't remove any existing
behavior. You can still use ldap auth against autofs if you want, and
that is the default in ipa-client-automount using the host credentials.

But that isn't what you originally asked about. You asked about the
mounts themselves requiring Kerberos security. If you want want Kerberos
in the NFS mounts there is more pain in EL 6 than in EL 7. The typical
workaround is to use a keytab.

We can only move the earth so much at a time.
