Hi John there is another way of tackling this problem, based on the following assumption We know the person who should be authorised, but we dont know what random set of attributes the IDP will provide for him (or if we do know, they are as horrible as you indicated in your example below). We

Hi John, It indeed looks interesting and enhancing the mapping engine is on ours to-do list for a long time. I'd be happy to talk this through during the summit. Do you think you will be able to come for a Keystone websso/federation Design Session on Wednesday at 16.30? Thanks, Marek On
