---++ Connecting to CERN AFS in Windows 7
   * AFS client authentication to CERN requires the following software to be installed on your desktop/ laptop: 
      * OpenAFS
      * Heimdal (Implementation of Kerberos v5) 
         * The kerberos configuration file is applied via group policies, which means the folder has to be deleted before Heimdal can be installed (C:\ProgramData\kerberos), otherwise the installer will fail.
         * After installing Heimdal, open a command prompt (Start -&gt; All Programs -&gt; Accessories -&gt; Command Prompt) and enter "gpupdate /force", you may have to do this a couple of times. 
         * The configuration file contains all the settings including the default cell (CERN.CH), used for obtaining tokens via the Windows AFS client.
         * The configuration file is available below.
   * To obtain a new AFS token open the AFS Client and right-click Obtain New Tokens, you can then enter your AFS Username and Password in the popup box.
