Hi Prabath,

Thank you very much for reply. 
My requirement is little bit changed, I want signed SAML token from STS,
since SAML token issued by STS would contain some user info in
AttributeStatement, requirement says it must be signed. The policy file
which you sent is more about signing the message using issued SAML token. In
my case SAML token is not protection token, its a supporting token. I am new
to WS security, and I am not able to find the sample which uses this type of
requirement. I read from specification and it says signed supporting token
is used for this purpose (getting signed token from STS). I would higly
appreciate if you can provide any sample policy file for this type of
requirement.

Thanks,
Amitesh
