SSO and SLO in standalone mode

SSO lets users sign in once and remain authenticated as they access services in the circle of trust.

SLO attempts to log out all session participants:

For hosted IDPs, single logout attempts to log out of all SPs with which the session established SAML federation.
For hosted SPs, single logout attempts to log out of the IDP that was source of the assertion for the user’s session.

Verify that the federation authentication module is present

Standalone mode requires that a Federation authentication module instance is present in the realm in which you define your circle of trust, identity providers, and service providers.

The module must be of type Federation, and also have the name as Federation.

AM creates a Federation authentication module when you create a new realm, so the required module is already available unless you explicitly deleted it. If you deleted the Federation authentication module and need to restore it to a realm, create a new authentication module named Federation of module type Federation. No additional configuration is needed.

Do not add the Federation authentication module to an authentication chain. The module is used for internal purposes.

JSP pages for SSO and SLO

With standalone mode, AM SAML v2.0 Federation provides JSP files that direct users to do SSO and SLO across providers in a circle of trust. AM has two JSPs for single sign-on and two JSPs for SLO, allowing you to initiate both processes either from the identity provider side, or from the service provider side.

The JSP pages are found under the context root where you deployed AM, in saml2/jsp/.

When you perform HTTP GET requests to these JSPs, there are several query parameters to specify. Which query parameters you can use depends on the JSP. When setting parameters in the JSPs, make sure the parameter values are correctly URL-encoded.

The JSP pages only support query parameters sent by using HTTP GET requests. Do not attempt to use HTTP POST or PUT requests to the pages.

IDP-initiated SSO JSP

idpSSOInit.jsp: Used to initiate single sign-on from the identity provider side, so call this on the identity provider not the service provider.

To ensure the redirect is permitted, add the URL to the RelayState URL List. For details of this setting, see the Reference section.
spEntityID: (Optional, for Fedlets) Use this parameter to indicate the Fedlet entity ID.

When missing, AM uses the first entity ID in the metadata.

Modify the SSO JSP page to indicate progress

During single sign-on login in standalone mode, AM presents users with a self-submitting form when access has been validated. This page is otherwise blank.

Perform the steps in the following procedure if you want to present users with something to indicate that the operation is in progress:

To modify the templates to add feedback that single sign-on is in progress, such as an image, edit the source of the AM Java Server Page, saml2/jsp/autosubmitaccessrights.jsp, under the file system directory where the AM WAR file has been unpacked.

When you add an image or other presentation element, make sure that you retain the form and Java code as-is.
Unpack the AM-7.3.2.war file.
Overwrite the modified saml2/jsp/autosubmitaccessrights.jsp file, where you unpacked the .war file.

Also, include any images referenced in your files.
Pack up your custom version of AM, and then deploy it in your web container.

ECP profile configuration

The SAML v2.0 Enhanced Client or Proxy (ECP) profile is intended for use when accessing services over devices like simple phones, medical devices, and set-top boxes that lack the capabilities needed to use the more widely used SAML v2.0 Web Browser single sign-on profile.

The ECP knows which identity provider to contact for the user, and is able to use the reverse SOAP (PAOS) SAML v2.0 binding for the authentication request and response. The PAOS binding uses HTTP and SOAP headers to pass information about processing SOAP requests and responses, starting with a PAOS HTTP header that the ECP sends in its initial request to the server. The PAOS messages continue with a SOAP authentication request in the server’s HTTP response to the ECP’s request for a resource, followed by a SOAP response in an HTTP request from the ECP.

An enhanced client, such as a browser with a plugin or an extension, can handle these communications on its own. An enhanced proxy is an HTTP server, such as a WAP gateway, that can support the ECP profile on behalf of client applications.

AM supports the SAML v2.0 ECP profile on the server side for identity providers and service providers. You must build the ECP.

By default, an AM identity provider uses the com.sun.identity.saml2.plugins.DefaultIDPECPSessionMapper class to find a user session for requests to the IDP from the ECP. The default session mapper uses AM cookies as it would for any other client application. If you must change the mapping after writing and installing your own session mapper, you can change the class under Realms > Realm Name > Applications > Federation > Entity Providers > IDP Name > IDP > Advanced > ECP Configuration.

By default, an AM service provider uses the com.sun.identity.saml2.plugins.ECPIDPFinder class to return identity providers from the list under Realms > Realm Name > Applications > Federation > Entity Providers > SP Name > SP > Advanced > ECP Configuration > Request IDP List. You must populate the list with identity provider entity IDs.

The endpoint for the ECP to contact on the AM service provider is /SPECP as in https://www.sp.com:8443/openam/SPECP.

The ECP provides two query string parameters to identify the service provider and to specify the URL of the resource to access.

metaAlias

This specifies the service provider, by default, metaAlias=/realm-name/sp, as described in MetaAlias.

RelayState

This specifies the resource the client aims to access, such as RelayState=https%3A%2F%2Fforgerock.org%2Findex.html. Make sure this parameter is URL-encoded.

For example, to access the service provider followed by the resource at https://forgerock.org/index.html, use https://www.sp.com:8443/openam/SPECP?metaAlias=/sp&RelayState=https%3A%2F%2Fforgerock.org%2Findex.html.

To ensure the redirect is permitted, add the URL to the RelayState URL List. For details of this setting, see the Reference section.
