SAMLv2 Writer Service URL

The Writer Service URL is used by the identity provider. After successful authentication, the common domain cookie is appended with the query parameter _saml_idp=entity-ID-of-identity-provider. This parameter is used to redirect the principal to the Writer Service URL defined for the identity provider. The URL is configured as the value for the SAML2 Writer Service URL attribute when a circle of trust is created. Use the format http://idp-discovery-host:port/deployment-uri/writer where idp-discovery-host:port refers to the machine on which the SAMLv2 Identity Provider Discovery service is installed and deployment-uri tells the web container where to look for information specific to the application (such as classes or JARs).
