Log into the Federation Manager as a Site Administrator (SA).
From the home page (SA Dashboard), scroll down to the "Existing Service Providers" section.
Find your Service Provider (SP); click its entity ID to enter the "View/Edit Service Provider" page.
"View/Edit Service Provider" is a step-by-step, multi-section form designed to guide you through the steps of registering a new identity provider in InCommon. The steps are listed on the left of the form.
NOTE: Since you cannot edit the Entity ID once your SP has been published to the InCommon metadata, the first step, "Entity" does not appear if this SP has been previously published to the InCommon metadata
Remember to navigate to "Review and Submit" to submit your entity for publication. Your changes won't be published to the InCommon metadata until you submit it for publication.
