OK.
Now, I guess it was not the intention to check *my* system... :-)

FWIW, here is what I get :

$ sftp -o "AllowedAuthentications password" "<user>@localhost"

warning: Authentication failed.
FATAL: ssh2 client failed to authenticate. (or you have too
old ssh2 installed,)
Disconnected; connection lost (Connection closed by remote host.).

I *can* use Reflection FTP in SFTP mode against the same user
on the VMS box. Refletion says (about the server) :

"SSH-2.0-3.20 SSH OpenVMS V5.5 VMS_sftp_version 3"

Anyway, I don't feel I'm of any greater help here... :-)
