Server password always required?

[Sanford Selznick]

Hi dropbear folks,

  On the linux client for spaceflight we're running dropbear: v 2017.75.
  On our Windows 11 server we're running: Open SSH Server v 9.5.0.0 on the bench.

1. We've generated keys with `dropbearkey` on an ubuntu 16 VM and moved them to  both machines above.

2. We can't run dropbearconvert on the linux client so we ran it on Ubunto to convert our private key.  We moved the result back to Linux.

  When we use this key we get the error back "String too long".

3. On the Windows box we have registered the public key (not from dropbearconvert) to the authorized_keys on the server with appropriate permissions.

  On the linux client we issue:

  `dbclient -i <path/to/identityfile> host at windowserver`

  `dbclient` always asks for the password for the windows box.  It does find the identity file, though.

  How do we fix this setup so we don't have enter our password every time we ssh?

Thank you,
  Sanford
