Now regarding the issue I get is that if I mount /share with autofs as: /etc/auto.master /share /etc/auto.share /etc/auto.share * -fstype=nfs4,rw,sec=krb5 nfs-server:/share/& It gets mounted, same permissions as on nfs-server: /share (0755) But if I mount it with a direct map of: /share -fstype=nfs4,rw,sec=krb5 nfs-server:/share in /etc/auto.direct and /etc/auto.master /- /etc/auto.direct Then it works as expected. I've also tried /share -fstype=bind /mnt/share, same results. This is with a freeipa server with kerberos / nfs and client, on Fedora 20. Any ideas on what to look at? Thanks.
