Red Hat: cannot register with any organizations

on RHEL 7.0 I keep getting the same error when I try to update a little my packages:

[root@wltemplate ~]# yum install telnet

Failed to set locale, defaulting to C
Loaded plugins: product-id, subscription-manager
This system is not registered to Red Hat Subscription Management. 
You can use subscription-manager to register.

No package telnet available.
Error: Nothing to do


[root@wltemplate ~]# subscription-manager register --username pirla.vernetto 
--password blablabla --auto-attach

pirla.vernetto cannot register with any organizations.

I have deperately tried to add some Organization (like "the Sons of the Desert") in the RHEL portal profile page, but I could not find any ...



I keep fighting on it....
