The access token manager instance requires these values to create an OAuth access token. ## About this task At runtime, a single sign-on (SSO) operation fails if PingFederate cannot fulfill the required attribute. ## Steps 1. On **OAuth Assertion Grant Attribute Mapping > OAuth Assertion Grant Attribute Mapping Configuration > Contract Fulfillment** , select a source from the **Source** list and then choose or enter a value for each attribute. The following table describes the available mappings for each **Source** value: | Source | Value | | -------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Assertion** | When selected, the **Value** list populates with attributes from the SAML assertion or the JWT.For example, to map the value of `SAML_SUBJECT` from a SAML assertion, or `sub` from a JWT, as the value of an attribute on the access-token contract, select **Assertion** from the **Source** list and **TOKEN\_SUBJECT** from the **Value** list. | | **Context** | When selected, the **Value** list populates with the available context of the transaction. Because the HTTP Request context value is retrieved as a Java object rather than text, use OGNL expressions to evaluate and return values. For more information, see Expression. | | **Extended Client Metadata** | Values are returned from the client record. | | **LDAP**, **JDBC**, or **Other** | When selected, the **Value** list is populated with attributes that you have selected from the datastore. Select the desired attribute from the list. | | **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 aren't enabled by default. Learn more about enabling and editing OGNL expressions in [Attribute mapping expressions](pf_attribute_mapping_expressions.html). | | **No Mapping** | Select this option to ignore the **Value** field. | | **Text** | When selected, the text you enter is used at runtime. You can mix text with references to any of the values from the SSO token, using the `${attribute}` syntax.When applicable, you can enter values from your datastore using the `$\{ds.}` syntax, where `` is any attribute that you have selected from the datastore. You can reference attribute values in the form of ${attributeName:-defaultValue}. The default value is optional. When specified, it's used at runtime if the attribute value is not available. Don't use ${ and } in the default value. | 1. Click **Next**.
