Hi Damien,

Thanks for your response.

I'm currently working on reproducing this with the hostkey-agent.sh test, but
I can consistently reproduce it using a clean OpenSSH repository. Here’s how:

1. Start the SSH agent.
2. Add two ECDSA keys to the agent.
3. Modify sshd_config:
     Set HostKeyAgent as the agent path.
     Add the public parts of the ECDSA keys to the configuration.
4. Start sshd.
5. Run the SSH client:
        Use default configuration, with no prior server keys in the known_hosts file.

In this setup, the server and client complete the key exchange
successfully. However, when the server attempts to prove the authenticity of
the second ECDSA key, the process fails as described.

I've attached logs and my configuration files for reference. Let me know if
I’m missing anything or if there’s anything else I should provide to help
replicate the issue.

Please tell me if i'm doing anything wrong, multiple mails.
Apologies for the multiple emails. I forgot to include the mailing list in my previous reply.
