Actually, I also turned on debug on the client, and it seems to indicate that I do auth, but am refused PTY access.

I do in fact allow PTY in the sshd_config, however doesn't the broker disallow this with the key that it adds? I see it adding the key with "no-X11-forwarding,no-pty,no-user-rc". So is this not the key that gets used, and I still have some sshd_config settings somewhere, or do I have to tell the broker to allow this and it will update the key's settings?

I am trying to get the broker to work with the auto login feature, and I can't seem to get it to work. I am using an ansible playbook and building a broker, and then 2 workstations. I setup wks1 to autologin and wks2 with out. I can use wks2 just fine, but when I try and use wk1, It seems the new key is added, and the workstation indicates that it accepts a session for my user. However the X2go client then shows me a login/password box rather than logging me into the session.

I have logs from the server and the workstation, can someone help point me in the right direction?
