cannot access files after upgrading to openafs 1.6.2-1

[shaniaki]

After upgrading to opanafs-1.6.2-1+ubuntu2.1, I cannot access my files anymore.

ls: cannot access /afs/it.kth.se/path/to/file: Permission denied

I authenticate and get the tokens using kinit and aklog without any errors reported, but cannot access the same files which I was working with regularly.

user@host:~$ aklog -d
