I have a strange issue. I am able to ssh from other client machines but one
specific client machine is causing problems. I think I have identified the
issue but I don't know how to fix it.
Here is a verbose ssh connection:

As you can see it tries to send the private key of ADAMS_Mac_FW even though
I specified tasneem. If I ssh from this same system to another BQ server,
it works fine (using password).

admin@<hostname2>'s password:
I'm not trying to use keys, I am happy with passwords (although keys would
be nice). Admittedly, I am not an expert in ssh.
Any ideas?
