Confluence Federated Search Results WebPart

[Poova Moodliar]

I cannot get Confluence Federated Search Results WebPart to work.
Im using sharepoint 2010 sp1. authentication is kerberos. latest confluence web part is installed
confluence is 4.3 open search 1.1 and sharepoint plug in is installed and working

both confluence and sharepoint test connection works.

erro that i get is :

Only NTLM, Basic or Digest Authentication is supported

I have tried all the option in the sharepoint search center when creating the federated search location
