[jcifs] NTLM http client uses Sun NTLM coming with JVM 1.4.2_10 instead of jcifs

[My Chi Doan]

Hi,

We have a ntlm http client (as example NtlmHttpClient.java), which 
authenticates user against a web application using
http://<NTdomain\login>:<password>@<host>:<port>/....

Depending on which JVM the client is using, we get different behaviors:

1) When using "stand-alone" JVM (version 1.4.1_01), the ntlm 
authentication works fine. It means the NT login is authenticated 
correctly according to the above url.

The command looks like:
C:\myjre\bin\java -Djava.protocol.handler.pkgs=jcifs -cp 
./jcifs-1.2.7.jar;. NtlmHttpClient <parameters..>


2) When using System JVM (version 1.4.2_10), regardless which login and 
password is used in the url above, always the user, who is logged in on 
the PC, is got authenticated. E.g. xxx works on PC of yyy and tries to 
call the ntlm client with his own NT login and password. The 
authenticaton is always perfomed for user yyy instead of xxx.
It looks like in this case the Sun's NTLM is used instead of jcifs.

The command looks like:
java -Djava.protocol.handler.pkgs=jcifs -cp ./jcifs-1.2.7.jar;. 
NtlmHttpClient <parameters..>


Did anybody experience the same problem? I searched in this newsgroup, 
but coulgn't find any posting related to that.

Is it possible to switch off the Sun NTLM and use jCIFS instead?

Any hint is highly appreciated.

Thanks, My Chi
