Hi Tom,

I suspect that the fact that you're delegating to an OP that only 
supports OpenID 2.0 is probably causing some compatibility problems.

The Yahoo OP does support delegation, and to the best of our knowledge, 
we are correctly implementing the OpenID 2.0 spec with regards to 
delegation. That being said, the OpenID 2.0 spec is a bit ambiguous 
regarding how delegation is supposed to work. Hopefully this can be 
cleared up in OpenID 2.1.

If you do need backwards compatibility with OpenID 1.1, as well as 
support for OpenID 2.0, then delegating to MyOpenID.com seems to work 
pretty well.

Allen
