> Actually, the problem definitely impacts PEAP/MSCHAPv2 (and I believe TTLS/MSCHAPv2 also because it's an error in MS-CHAP, but we don't use TTLS so I can't test that). (I haven't thought about it enough to know whether it affects v1, but it definitely occurs with v2 as that's where I found it.)

hmm, okay - I'll only be able to introduce core systrems with this patch in place
after 2nd October - we currently have a change freeze on main systems until then
