OS deployment: You must provide exactly one of DomainID or DomainName in a Scope with ProjectName

[sneumann]

Deploying in the Bielefeld de.NBI OpenStack works via ./phenomenal.sh deploy ostack -c config.ostack-cebitec.sh.

But deployment via the portal fails in the terraform step:

Error running plan: 6 error(s) occurred: 
* module.node.provider.openstack: You must provide exactly one of DomainID or DomainName in a Scope with ProjectName * ```

Discussions in slack in #tech on Oct 24th at 9:48 AM and later surfaced 
that Giessen does not support keystone v2 authentification. 

The proper way to get/set the `OS_*` variables would be to download 
the OpenStack RC file after logging in. Caveat: `source openrc.sh` might ask 
for the password interactively. That would require to `grep -v` the password prompting out. 

Happy to help when required. Yours, Steffen
