My $HOME on a server  is in a Andrew file system,  and the server runs kerberos. I created a tmux session, wherein I ran a shell process. Then I detached it, and logged out, and after a while logged in again and reattach the tmux session. In the shell process in tmux, I found that I didn't have permission to access my (non-directory) files in $HOME. I checked my ticket and it didn't expire, and I renewed it by running krenew and still didn't have permission.$ ls -lls: cannot access README: Permission deniedls: cannot access setup.sh: Permission deniedls: cannot access setup.sh~: Permission deniedtotal 14drwxrwxr-x.  2 t 2048 Apr  6 21:48 bindrwxrwxr-x. 11 t 2048 Apr 24 18:16 data???????????  ? ?    ?     ?            ?
