Many thanks to everyone who helped with this.
Of 7 IdPs tested, 4 worked just fine, 2 failed with the same message as
mine, and one failed in a new and exciting way. Simon tracked the problem
to some stale metadata at the SP end which was confusing it when dealing
with IdPs like mine which are only in the UK Federation. We still don't
know why only some such IdPs were affected.
