For initial steps to configure identity provider (IdP) adapter instances or authentication policy contracts (APC), see Managing authentication source mappings.

If you have selected the failsafe option on the Mapping Method tab and the Send user to SP using default list of attributes option on the Failsafe Attribute Source tab, define the default values that should be sent in the single sign-on (SSO) tokens to the SP.

On the Attribute Contract Fulfillment tab, you must complete the following steps for each adapter instance or APC.
  1. Select a source from the Source drop-down list.
  2. Select a source from the Source list and then choose or enter a value. You must map all attributes. See the following table for more information.
    • Adapter or Authentication Policy Contract (the authentication source)

      When selected, the Value list is populated with attributes from the authentication source. Select the desired attribute from the list. At runtime, the attribute value from the authentication source is mapped to the value of the attribute in the SSO token.

      For example, to map the value of the HTML Form Adapter's username attribute as the value of the SAML_SUBJECT attribute on the contract, select Adapter from the Source list and username from the Value list.

    • Context

      When selected, the Value list populates with the available context of the transaction. Select the desired context from the list. At runtime, the context value is mapped to the value of the attribute in the SSO token.

      Important:

      If you are configuring an SP connection to bridge one or more identity providers to a service provider, consider mapping the original issuer of the assertions into an attribute by selecting Context as the source and Authenticating Authority as the value. This is important when bridging multiple identity providers to one service provider, where the service provider should take the information about the original issuer into consideration before granting access to protected resources.

      For more information, see Bridging multiple IdPs to an SP.

      Note:

      Because the HTTP Request context value is retrieved as a Java object rather than text, use OGNL expressions to evaluate and return values (see Expression).

    • Expression

      When enabled, this option provides more complex mapping capabilities, such as transforming incoming values into different formats. Select Expression from the Source list, click Edit under Actions, and compose your OGNL expressions. All variables available for text entries are also available for expressions. For more information, see Text.

      Expressions are not enabled by default. For more information about enabling and editing OGNL expressions, see Attribute mapping expressions.

    • No Mapping

      Select this option to ignore the Value field, causing no value selection to be necessary.

    • Text

      When selected, the text you enter is mapped to the value of the attribute in the single sign-on tokens at runtime. You can mix text with references to any of the values from the authentication source using the ${attribute} syntax.

      Tip:

      You can reference attribute values in the form of ${attributeName:-defaultValue}. The default value is optional. When specified, it is used at runtime if the attribute value is not available. Do not use ${ and } in the default value.

      Tip:

      Two other text variables are also available: ${SAML_SUBJECT} and ${TargetResource}. SAML_SUBJECT is the initiating user (or other entity). TargetResource is a reference to the protected application or other resource for which the user requested SSO access; the ${TargetResource} text variable is available only if specified as a query parameter for the relevant endpoint (either as TargetResource for SAML 2.0 or TARGET for SAML 1.x).

  3. After all attributes have been mapped, click Next to save changes.
