An entity group is just like a folder that allows you to manage different kinds of federation members. One of the most common ways to group federation members is by trust level.
When you create an entity group, the Identity Providers and the Service Providers records will be displayed. Then you could add identities and services selecting the proper record.
- Entity Group: name of the group.
- Url Metadata: will be the URL of an external entity group when the entity group was esternal.
- Providers: by default, it creates two groups, an identity provider and a service provider.
