[security-dev] How to configure ServiceProviderAuthenticator to do this ?

[Pedro Igor Silva]

Yeah, there is

IdP SSO Metadata wantAuthnRequestsSigned

and

SP SSO Metadata authnRequestsSigned

The first is to indicate that IdP should enforce signatures for authnrequests. The second one to indicate if authn requests must be signed by the SP.

This is something we need to review in PL IdP. Today it is only considering the authnRequestsSigned from SP metadata. But it should also understand wantAuthnRequestsSigned.

The same thing at the SP side, we need to consider authnRequestsSigned. And this is what Adam is looking for ...

Regards.

I think you are correct Pedro, i was not thinking about the fact that 
enabling signing at the IdP side is separate from the SP side as well.  
Checking the configs on my dev idp I see the following:

For my IdP:
picketlink.xml -> supportSignatures=true
sp-metadata.xml  wantAssertionsSigned=true authnRequestsSigned=false

for my test SP:
picketink,xml --> SupportsSignature=true

Looking at the SAMLtracer output, i see that the incoming authn request 
is being signed, but that the IdP is not validating the signature.
