Hi folks,

I wonder, if there is anyone here, who has an actual slurm running on 
CentOS 7.4 with the (slurm-)native X11 forwarding mechanism.

Is Untrusted X11 Forwarding (-X) needed or does Trusted X11 Forwarding 
(-Y) also function?

For some reason, we cannot use ssh -X from a CentOS 7.4 client to a 
CentOS 7.4 server. We always get the following message:
Warning: untrusted X11 forwarding setup failed: xauth key data not generated

This does not happen, if we login from a Centos 6.9 client. Really 
strange ...
