I found no major issues with this document. I support publishing it if the minor issues below are resolved. The document is written in a rather information dense style, but I can't come up with any easy way to make it more accessible. More examples and illustrations would help, but I don't see this as sufficient reason to not move forward. /Simon Minor issues: The naming extensions [I-D.ietf-kitten-gssapi-naming-exts]to the ^ insert SPC mechanism allows an Authentication/Authorization/Accounting peer to ^ ...
