Torsten,
the people answering on this list are generally competent and helpful.
But they are not magicians.  You seem (so far) to be asking something impossible.
1) if the server sends to the client an authentication header saying HTTP Basic, then the

client will popup a builtin HTTP Basic dialog (which you do not want)
2) if the server sends to the client an authentication header saying something else, then

the client cannot handle it

1 + 2 = solution impossible

You mentioned before that with another server than Tomcat, you solved this apparently 
impossible problem.  Can you tell us how ?

Or else, can you tell us which authentication methods, /apart/ from HTTP Basic, the client

does support ?
