As promised yesterday, I am about to start to query to Windows OpenAFS 
community
on a variety of topics related to the use of OpenAFS on Windows.  Some 
of them may
seem trivial and others may result in serious debates.  I hope that the 
community is
interested in providing feedback.

For those who will be attending the OpenAFS Best Practices Workshop

     http://www-conf.slac.stanford.edu/AFSBestPractices/

I will be in attendance and will be hosting a session (currently 
scheduled for Wed
March 24th) entitled "Future Directions for the AFS Client on Windows". 
This session will be a further attempt to engage the interested 
community in a
discussion on the future of OpenAFS on Windows 2000, XP, 2003 and beyond.
I hope you will be able to participate.

Each of the e-mails to follow will focus on a single topic.
I am doing so in order to try and keep the threads of discussion focused.
The initial set of topics are going to be based on coding which I 
performed under
contract for Skyrope LLC.  <http://www.skyrope.com>  Skyrope graciously 
agreed
to donate this work to OpenAFS.ORG in Dec 2003.  Unfortunately I have 
not had
time to attempt to merge this work into the CVS HEAD until the present time.

The Skyrope work attempted to improve on the end user experience of using
OpenAFS in the following ways:

    * Obtain tokens using renewable Kerberos 5 tickets in order to
      reduce the need for end users to renew expired tokens
    * Monitor the list of IP Addresses in order to detect changes
      in the network configuration which might affect the reachability
      of cells or the state of the AFS Client Service.  When cells
      are newly reachable, obtain tokens for the cells.  If the AFS
      Client Service is not running, start it.  If tokens are expiring
      attempt to renew them.
    * Use KDC probes to detect the accessibility of realms/cells.  If
      the KDC is not reachable, do not prompt the end user for a
      username and password.  (fs probe is not implemented on windows)
    * Automatically obtain tokens using the Windows Logon Session
      Kerberos credentials (if available)
    * Allow tokens for multiple cells to be obtained by using the
      same Kerberos 5 tickets.  (no UI yet implemented)
    * Perform drive mapping persistance by tracking it within the
      afsdsbmt.ini file instead of relying on the Windows Shell
      to persist the state.
    * Add new afscreds.exe command line options and change the
      default set used when creating the "AFS Credentials" shortcut
      in the Start Menu->Programs->Startup folder.

I look forward to your input.

 Jeffrey Altman
