NTLMv2 authentication of Web Services to work with WebLogic
v9.2

Hi All

Have any one implemented NTLMv2 authentication of Web Services to work with
WebLogic V9.2.

I need to invoke a windows integrated authenticated protected (with NTLMv2) web
service from java web services client that is deployed within a web service
application running on WebLogic Server V9.2.

I think Weblogic does not support NTLM authentication out of the box as of now.

If WebLogic needs to support NTLM, I should write a custom authentication
provider and Challenge Identity Asserter as explained in:
http://edocs.bea.com/wls/docs92/dvspisec/atn.html
http://e-docs.bea.com/wls/docs92/javadocs/weblogic/security/spi/ChallengeIdentit
yAsserter.html
http://edocs.bea.com/wls/docs92/dvspisec/ia.html#wp1175329.

I have implemented just custom authentication provider and made it to work.

My Question here is:
1) Has anyone successfully implemented writing a Challenge Identity Asserter?
2) I couldn't find any samples or code on how to implement a challenge identity
asserter.
3) If anyone had made a Challenge Identity Asserter to work, can you provide
with some sample code or some directions on how to implement it.
4) BEA document on this very abstract on there is no details on it.

Please help me to get this work.
