Hi Jeff and Janelle,

I am glad you got things working, but I am not convinced this is the best way
to do it. The proxy is needed for SSSD SSH integration (public keys and
fingerprints), if the proxy is buggy, we should fix. And in order to fix it, it
would be great to get our hands on the logs showing the fault - CCing Jakub and
Honza on this one.

Thanks for help,
Martin
