Using Foreman 1.5.0 I renamed the host 'myproxy.DOMAIN' to 'globus-id.DOMAIN' which was successful. However the class parameters that were overridden no longer are associated to that host. An attempt to name the host back to its original name fails.

ActiveRecord::RecordInvalid
Validation failed: Match fqdn=myproxy.DOMAIN does not match an existing host
