[squid-users] squid/ads problem - no username handed over?

Hello List,
I am somewhat stuck here...
I have successfully intregrated my linux box (suse 9.2) into an active
directory domain and I can access the proxy squid on it perfectly.
Now I want to combine the two services, like I did several times before,
with no problem. [A perl skript is called which checks whether the user
is in an active directory group which is allowed to acess the
internet.]
But this is the first time with suse 9.2, and now i run into problems: I
get FATAL errors in my squid cache.log file.
------------------------
FATAL: authenticateNTLMHandleReply: called with no result string
Squid Cache (Version 2.5.STABLE6): Terminated abnormally.
------------------------------
Normally, the browser should hand over the User name to squid, but it
doesn't - see my access.log:
