As described in last night's e-mail, I am merging in some significant 
new functionality
which may or may not be immediately stable in all environments.  
Therefore, it is my
desire to conditionally enable this functionality based upon registry 
settings either
global to the system or local to the user. 

In the past all of the configuration settings have been stored either in 
old style
profile files (.INI) located within the %windir% directory; or placed 
within the
Local Machine Hive of the Registry under the Transarc organization name.

    HKLM\SYSTEM\CurrentControlSet\Services\TransarcAFSDaemon
    HKLM\SOFTWARE\TransarcCorporation\

I propose that existing parameters stored in the registry be kept in 
their existing
locations.  However, all new registry parameters affecting the client 
experience
be stored under the roots:
   
    HKLM\SOFTWARE\OpenAFS.ORG\
    HKCU\SOFTWARE\OpenAFS.ORG\

For every end user parameter there will be a system-wide default which is
superceded by the local-user specified value.

For the first two parameters I wish to propose are:

    Key = AFSClient

        UseKFW (DWORD) - Default is 0; 1 activates the use of KFW for
        Token acquisition

        AFSCreds Parameters (SZ) - Default is ""; A string of parameters
        to be used when creating the afscreds.exe shortcut in the
        Start->Programs->Startup folder for the current user. In case
        you were not aware there are a number of parameters which can be
        passed to afscreds.exe. 

        -a (new): activate auto-initialization of the token cache. 
        Obtain tokens from existing kerberos credentials if possible or
        display a klog dialog

        -m: renew drive mappings

        -n (new): enable network detection.  when active changes in the
        IP Address assignments for the local machine will cause afscreds
        to attempt to verify the reachability of the default cell and
        restart the AFS Client Service if it is not running

        -s: show the afscreds property dialog upon startup

        -q: do not display the afscreds wizard if the AFS Client Service
        is not running

        -e: send a message to an existing afscreds.exe instance to exit

        -i: install a shortcut to afscreds into the Startup Folder

        -u: uninstall the afscreds shortcut from the Startup Folder

        -x: create drive mappings


Are there any objections to this proposal? 

Or perhaps alternative suggestions?

Thanks

Jeffrey Altman
