am trying to connect local->cntlm->company proxy->rhcloud host.

I have the keys uploaded to rhcloud and GitHub. With the current configuration with corkscrew i am able to connect to git via ssh. However ssh -v to host doesn't work.

The fingerprint is same when I check with ssh key-gen list in local and rhc show-app list for Openshift.

Here is the trace.

Any pointers on why public key is denied?
