License Self-Service Portal gone? (dell.com/support/retail/lkm doesn't work anymore!)

I'm trying to buy/apply an iDRAC7 Enterprise license to my R320 server (currently only have "Basic Management"). However, when I click on "To manage changes to or purchase new licenses visit the License Self-Service Portal" in the iDRAC web interface, or open the link to www.dell.com/support/retail/lkm mentioned in the various iDRAC7 licensing manuals, it always redirects to the "Retail Registration" page for Dell.

Where is the License Self-Service Portal, it used to be there in the past?

Thanks
