Quite a while ago (12 to 18 months?) before Cygwin OpenSSH could impersonate a user, there was some experimental activity in OpenSSH to allow multiple authentication methods. There was a patch to add this on the OpenSSH archives. I experimented with this to require public key followed by password authentication. This got me the security of a public key authentication and also got me a password to change user ID. When Cygwin added the impersonate user ability, I dropped this activity. ...Karl >From: Olivier ALLART >To: Cygwin List >Subject: Re: SSHD, Cygwin and Windows 2003 : continued with user rights >Date: Thu, 18 Sep 2003 01:22:48 +0200 > >Larry Hall wrote: > >>Hm, I thought I was clear.
