Some Service Provider software does not support SAML Metadata out-of-the-box.
Although Metadata might include more complex data, a sample minimal Metadata for a service provider is shown below. Enter the data specific for your SP and click the button. Then copy the generated Metadata and paste it into the SSOCircle Service Provider Import Page.
But remember that the entityID must be a unique identifier for your SP. With approaching 10.000 service providers in the SSOCircle of Trust many names are already used especially IDs similar to http://localhost:8080.
