Comment 2 for bug 409438

I have recently set up an Ubuntu 9.10 release candidate system for testing, and I am able to reproduce this
problem there, too. My new test system does not us the automounter - I encounter the same problem with
a statically (fstab) mounted NFS4 sec=krb5 home directory tree and two kerberised login accounts.

It seems to to affect a wide range of kernel versions, both i386 and amd64 architectures, and be
observable/reproducible on any system using pam-krb5 for authentication/ticket acquisition and kerberised
NFS4 home directories.
