Hi Pete,

A couple of comments.

First of all, the KClient API has not gone away in KfM 4.0.3, even 
though the KClient control panel has been replaced.  Quite a bit of 
work was done to make sure that existing KClient applications, even 
those that talked to the KClient v1 API, worked with the "new" KfM. 
The way KfM 4.0.x is designed, you will still "play nice" with other 
KfM using applications when you're using the KClient API.

Is your problem that the modified KClient-using Newswatcher doesn't 
seem to work with KfM 4.0.3?  If so, you may just want to work on 
upgrading the KClient code it uses.

You can find links to a KClient Transition Guide and documentation 
for the KClient 3.0 API at:


The new control panel really doesn't have a programmatic interface; 
it is just a GUI for managing your Kerberos tickets.  The Kerberos 
Library contains all the programmatic interfaces, which are detailed 


Also, consider that you need to make sure that your news server has 
GSS/Kerberos v5 support before you consider converting Newswatcher 
(the client application) to support GSS API.  If the server doesn't 
support it, adding support to just the client will not work.

Hope this helps,
