You would need to set up Open AM as a SAML 2.0 Identity Provider and
provide the Identity Provider Metadata in the cf-manifest under
login->saml->providers section

login.saml.providers: description: "Contains a hash of SAML Identity
Providers, the key is the IDP Alias, followed by key/value pairs. To learn
more about how to setup a saml identity provider go to
https://simplesamlphp.org" example: my-identity-provider:
metadataTrustCheck: false idpMetadata:
http://my.identityprovider.com/saml2/idp/metadata.php nameID:
urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress
assertionConsumerIndex: 0 signMetaData: false signRequest: false iconUrl:
