issue with private key.

[MetalJacx]

Can seem to figure out what I am doing wrong here. With the server having forced settings of public key. I can't get it to leverage it. Seems to try to interact with username/password.

Expected behavior

Expect to connect to host leveraging private key instead of username password.

Actual behavior

Looks to be leveraging keyboard interactive to log in. Instead of private key.
