Steps to reproduce

Hi, I would like to enable authentication delegation through SSHD in order to use kerberos. The aim is to be able to run powershell commands like get-childitem and Invoke-DbaQuery through ssh.

When I enable the “GSSAPIAuthentication yes” option, I can restart the SSHD deamon without error.

But when I activate the “GSSAPIDelegation yes” option I get the error “Bad configuration option: GSSAPIDelegation”.

My configuration :

Windows Server 2022 21H2 OpenSSH_for_Windows_8.1p1, LibreSSL 3.0.2

Expected behavior

Service SSHd Up

Actual behavior

Service SSHd Down

GSSAPIDelegation is an argument for ssh_config, not sshd_config. Passing -K as a command-line argument to ssh has the same effect as setting it in ssh_config.
