I've got an evaluation licence for Red Hat version 6.3.
I've registered the desktop that I'm using and that shows up correctly in the online portal.
However, when I attempt to use the subscription manager to link the subscription I get the following error: "Too many content sets for certificate".
This happens both with the command line interface and the GUI tool.
Red Hat help points me at https://access.redhat.com/knowledge/solutions/129003 but I don't really understand what I'm supposed to do. Is there an updated 'subscription-manager' amongst the downloads that they refer to??
