If you have set up federation with another provider over the SAML 2.0 or WS Federation protocol and you change the base URL of Identity Server, you need to update the provider with the new metadata to reestablish the trusted relationship. If the provider is another Identity Server, follow the procedure below to update the metadata; otherwise, follow the provider’s procedures.
On the Home page, click Applications > Select a Cluster > [application name] > [Protocol] > [Provider] > Metadata.
Click Reimport Metadata.
Follow the steps in the wizard.
For more information, see Section 2.8.7, Managing Metadata.
