Running chef-client errors out with:

Chef encountered an error attempting to create the client ""

Authorization Error:
Your validation client is not authorized to create the client for this node (HTTP 403).

Possible Causes:
* There may already be a client named ""
* Your validation client (chef-validator) may have misconfigured authorization permissions.

[2018-05-03T14:28:42+02:00] FATAL: Stacktrace dumped to /var/chef/cache/chef-stacktrace.out
[2018-05-03T14:28:42+02:00] FATAL: Net::HTTPServerException: 403 "Forbidden"


On the admin node delete the client:

knife client delete

Then on the failing node run:

crowbar_join --setup

crowbar_join --start

This will delete the public key of the node from the chef-server.  It won't change any of the node attributes.
The crowbar_join call will then generate a new key-pair.


File /etc/chef/client.pem is missing for some reason.
