Comment 61 for bug 84899

I just met problem like this. It prevented logging on to a server completely.

Here's a log:

ssh -vvv <email address hidden>
....
debug1: Authentications that can continue: publickey,gssapi-with-mic,password
debug3: start over, passed a different list publickey,gssapi-with-mic,password
debug3: preferred gssapi-keyex,gssapi-with-mic,publickey,keyboard-interactive,password
debug3: authmethod_lookup gssapi-with-mic
debug3: remaining preferred: publickey,keyboard-interactive,password
debug3: authmethod_is_enabled gssapi-with-mic
debug1: Next authentication method: gssapi-with-mic

(time passes)

After setting "GSSAPIAuthentication no" connection works fine.
