First of all, I find the content compelling and I support moving forward. This draft seems to have been “worked over” pretty well.

The precise form of pake specified is apparently unique in some details. I wonder if we should get the cfrg to review and comment on it. 

There are a number of TBDs which need finalizing. (pp 6, 9, 12, & 16)

Section3 should include pointers to where the prerequisites are specified. In the case of PA-FX-COOKIE and KDC_ERR_MORE_PREAUTH_DATA_REQUIRED that is rfc6113, section 5.2.  PA-ETYPE-INFO2 is rfc4120, section 3.1.3.

[NIT] Section 4.3, para 2: Delete the word “Next”. On my first reading that led me to think it was describing what to do after “the client completes. . .”. It actually describes the *first* thing to do (in the third pass). I’ve now read it enough times that I’m no longer qualified to say how important that is.
