Configuring SAML 2.0 SSO

Learn about the properties that you need to set for configuring SAML 2.0 SSO.

Before configuring Edge Flow Manager (EFM) to use SAML, you should first set up an SAML client application configuration in your SSO identity provider. For information about how to do this, see SSO identity provider setup.

Before configuring SAML, EFM should already be configured to use TLS. SAML authentication requires passing an access token to EFM that is vulnerable to compromise if TLS is not enabled, and therefore EFM does not allow using SAML authentication without TLS enabled. For more information on enabling TLS in EFM, see TLS configuration for EFM.

EFM supports Identity Provider (IdP) and Service Provider (SP) initiated flow.

To enable SAML in EFM, the following properties must be set in the file:

    Set to true to enable SAML authentication.


    Identity provider metadata location that is used for dynamic configuration.


    The name of a SAML assertion attribute containing group names the user belongs to.

Optional parameters for further configuration are as follows:
    The application-defined unique identifier that is the intended audience of the SAML assertion. It is advisable to use this property when the default {baseUrl} dependent Entity ID is undesirable.

    Private key location for signing SAML request.


    Private key password.


    Certificate location for signing SAML request.


    Name of the attribute field of the SAML response which can be used to populate the display name of the user.

EFM supports SAML metadata based configuration. SAML metadata is an XML document which contains information necessary for interacting with SAML-enabled identity providers. To obtain such a metadata file, you need to create a new application integration at your identity provider. For more information, see IdP documentation.

To configure the application at the IdP, the following EFM specific properties are needed:
  • Single sign-on URL

    This property is also known as SAML Assertion Consumer Service (ACS) URL. In case of localhost, it is https://localhost:10090/efm/login/saml2/sso/efmSaml.

  • Audience URI (SP Entity ID)
    By default, this is https://localhost:10090/efm/saml2/serviceProviderMetadata/efmSaml.

After the successful IdP configuration, you can obtain the metadata.xml file. The location of that metadata file should be set in the property. The value can either be a local file system path or a location hosted by the identity provider.

If the identity provider supports SAML request signing and it is enabled, you can set up the required key and certificate in the* properties. The values should be file system locations, except the privateKeyPassword.

Without additional configuration, the user name is equal to the display name in EFM. If you want to provide a different display name, set up an SAML attribute at the IdP and set the name of the SAML attribute in the property.
