-When you login with your password the folder :file:`MPIB-SAMBA` should be
-populated with all the detected file servers, like :file:`mpib06, mpib10 or
-dfs1`. You can simply navigate to the desired folder and use :program:`cp, mv,
-rm etc` on those folders:
-
-.. code-block:: bash
-
-   krause@master:~> $ cd MPIB-SAMBA/dfs1
-   krause@master:~/MPIB-SAMBA/dfs1> $ ls
-   Bibliothek  FB-ABC  FB-ARC  FB-GG  FB-LIP  Misc  MPFG-Affekt

-After a while the automatic access granting ticket will expire and you might see an error like this:
-
-.. code-block:: bash
-
-    krause@master:~> $ ls MPIB-SAMBA/mpib11
-    ls: cannot open directory MPIB-SAMBA/mpib11: Permission denied

-In that case you can run the script :program:`remount-smbnetfs.sh` to manually
-refresh your ticket and re-mount the network folders in :file:`MPIB-SAMBA/`. No
-shell or program may access the folder at that time.
