agent runs fail on hosts with upper-case characters in hostname

After installing the agent on a new server and approving the node request, I tried to run an agent test but received a number of errors:
Warning: Unable to fetch my node definition, but the agent run will continue:

The agent name doesn't appear to satisfy the default auth.conf rules, and it defaults to the deny all rule as a result. Adding "allow *" to the default rule will allow a successful test. I believe the issue is that the certificates are all generated using the hostname in all lowercase (mjstest2.lab.raindanceit.com.pem in this instance), but puppet.conf uses
certname=MJSTEST2.lab.raindanceit.com

Changing this line to all lowercase will allow a successful agent run as well.
