Hi again Everybody,
 Second week I have been batling with the problem...
A lot of problems a have already solved on the way thanks to your advises.
 Now I have done everything in compliance with the manual (
http://www.grolmsnet.de/kerbtut/)
 I have created a fresh domain account in the test domain (because I cannot
use production one) , have mapped principal to it, etc.
 And I'm getting now the error (in the Apache's error_log file) :
 --------------------- Apache's LOG
