The Services > Endpoints folder contains a list of the endpoints that are served by AD FS.

The Metadata section contains a path to the FederationMetadata.xml file which can be imported into the LoadMaster when configuring the SAML domain. This path will form part of a full URL which includes the federation service server. Go to this URL (for example, https://<FQDN>/FederationMetadata/2007-06/FederationMetadata.xml) in a web browser to download the metadata file which can then be imported using the IdP Metadata File field in the LoadMaster. Importing this file automatically populates the IdP Entity ID, IdP SSO URL and IdP Logoff URL fields with the relevant data.
