Once logged into the Console, you will be presented with a Dashboard. 

This Dashboard contains a My Service Providers section and a My Organizations section. The My Service Providers section lists any service providers which you are eligible to administer. My Organizations section lists any organizations which you are eligible to administer. Note: If you are not an Organization-level admin, you will not see the My Organizations section.

The eligibility of which service providers you can administer is determined by either an Organization-level Admin (if you are using the Enterprise version of the Gateway), or by the data contained in the federation metadata for the service provider.
