Directory Programming .NET

Hi,
I am getting a signature verification failure while deploying ADFS.
Does anyone have an idea to fix that issue?
Thank you very much in advance.

I don't think I can help you with this.  It looks like ADFS doesn't think the digital signature coming from the Sun OpenSSO signed token is valid for some reason.  I think you might need to investigate with Sun and MS directly.
