The server is Samba 4.6.7. Users are stored in LDAP and authenticated with Kerberos. Here are the mount options I am using:

  user=machine-root,multiuser,sec=krb5,x-systemd.automount

Unfortunately, I don't have a different file server to play with, but I suspect it is the 'multiuser' option that is breaking things.

Here are the contents of /proc/fs/cifs/DebugData after the initial mount:

And here it is again after I try to `ls /nfs/users/test` as a normal user:
