[netconf] update to ssh-server draft

[Balázs Kovács <[e-mail]>]

Hi,

The new local configuration in ssh-server draft seem to have some not appropriate terminology. The public key of the users should be maybe not called host keys?

In RFC7317:

            +--rw user* [name]
               +--rw name        string
               +--rw password?   ianach:crypt-hash
               +--rw authorized-key* [name]
                  +--rw name         string
                  +--rw algorithm    string
                  +--rw key-data     binary

In ietf-ssh-server@2019-11-20:

       |  +-- supported-authentication-methods

       |  |  +-- publickey?   empty

       |  |  +-- passsword?   empty

       |  |  +-- hostbased?   empty

       |  |  +-- none?        empty

       |  |  +-- other*       string

       |  +-- users {client-auth-config-supported}?

       |  |  +-- user* [name]

       |  |     +-- name?        string

       |  |     +-- password?    ianach:crypt-hash

       |  |     +-- host-keys!

       |  |        +---u ts:local-or-truststore-host-keys-grouping

Maybe this latter better serves hostbased key authentication? Was that really the intention? Should it be possible to select between user authorized key and host based auth? So for example, if one selects publickey, then should it still configure a trusted host key?
