1) Ubuntu 14.04
2) 3.13 kernel or mainline kernel 3.19.
krb5-user [1.12+dfsg-2ubuntu5.1]
nfs-common [1:1.2.8-6ubuntu1]
3) What should happen:
Start as unpriviledged (in a kerberos sense) user with access to a kerberos protected NFS share (in this case it contains home directories)
kinit user1
ls ~user1 #Test user1 permissions, this should always succeed (and does)
kdestroy #should destroy user1 permissions
kinit user2
ls ~user2# this should succeed!
ls ~user1# this should fail!
4) What happened instead:
After kinit user2:
ls ~user2# this FAILS
ls ~user1# this still WORKS
