Misleading nodes quickstart howto
In the howto, there is no note on enabling the oauth in server.conf on child side. This leads into sync not running and weird log messages that does not point person to the root cause, namely:
Dec 1 14:08:26 pulp02 pulp: pulp.server.webservices.middleware.exception:INFO: Authentication with username None failed: invalid SSL certificate. severity=info
Please update quickstart (and potentially even previous long howto) with mentioning need of setup oauth in server.conf on child node.
