Last Call Review of draft-igoe-secsh-x509v3-
review-igoe-secsh-x509v3-secdir-lc-mcgrew-2010-11-22-00

I have reviewed this document as part of the security directorate's  


ongoing effort to review all IETF documents being processed by the   


IESG.  These comments were written primarily for the benefit of the  


security area directors. Document editors and WG chairs should treat  


these comments just like any other review comments.






The document describes how to use X509 and OCSP within SSH.  It is  


clearly written, and the security considerations section is  


appropriate (it mostly points to the relevant sections in the SSH,  


X509, and OCSP RFCs).






I have one nit, which is wording that authors might want to change for  


clarity.  Section 4 says "The mapping between certificates and host  


names is left as an implementation and configuration issue for  


implementers and system administrators."   I believe that what is  


meant is that "The method that the server uses to verify that the host  


certificate and key actually belongs to the client host named in the  


message is out of scope of this note", to use language from RFC 4252.
