I ran the basic Client/Server programs in the first chapter of the GSS
tutorial "Use of JavaTM GSS-API for Secure Message Exchanges Without JAAS Programming" in

file:/usr/web/work/j2se/1.4/docs/guide/security/jgss/tutorials/BasicClientServer.html

The program passed OK on Solaris and Window NT but failed on Window 98.

The following is the log from running the script:

To replicate the problem you can run the demo program given in the tutorial
or the attachments which also includes the script to launch the server
and the client programs.
