RHEL 6.6: [Errno 14] PYCURL ERROR 22 - “The requested URL returned error: 403 Forbidden”

Fixed it.

What i did:

1. Fill up the rhsm.conf file with proxy settings ( /etc/rhsm/rhsm.conf )
2. reboot the machine
3. try to install: root@mymachine:~# yum install -y openmotif22.i686 openmotif22.x86_64 -> fail, same error
4. yum clean all -v
5. yum repolist -v
6. root@mymachine:~# yum install -y openmotif22.i686 openmotif22.x86_64 -> it worked... No idea why, but the reboot is the key.

I already had done those steps without the reboot, it didn't work.
