The USER_KEY attribute is the identifier of the persistent grants. The USER_NAME attribute presents the name shown to the resource owner on OAuth user-facing pages. If extended attributes are defined in System > OAuth Settings > Authorization Server Settings, configure a mapping for each attribute.

Important:

The USER_KEY attribute values must be unique across all end users, because the USER_KEY attribute is the user identifier to store and to retrieve persistent grants. For example, the sAMAccountName attribute value of an end user in one domain might match that of another end user in another domain. In this case, you can map the Subject DN attribute to the USER_KEY attribute.

  1. Go to Authentication > OAuth > IdP Adapter Grant Mapping and select your mapping, or click Add Mapping.
  2. On the Contract Fulfillment tab, select a source from the Source list and then select or enter a value for each attribute in the contract.
    You can map each attribute from one of the following sources:
    • Adapter

      When selected, the associated Value drop-down list contains attributes configured in the IdP adapter instance.

    • Context

      Values are returned from the context of the transaction at runtime.

      Note:

      If PERSISTENT_GRANT_LIFETIME is an extended attribute in System > OAuth Settings > Authorization Server Settings, you can set the lifetime of persistent grants based on the outcome of attribute mapping expressions, or the per-client Persistent Grants Max Lifetime setting.

      • To set lifetime based on the per-client Persistent Grants Max Lifetime setting, select Context from the Source list and Default Persistent Grant Lifetime from the Value list.
      • To set lifetime based on the outcome of attribute mapping expressions, select Expression as the source and enter an OGNL expression in the Value field.

        If the expression returns a positive integer, the value represents the lifetime of the persistent grant in minutes.

        If the expression returns the integer 0, PingFederate does not store the grant and does not issue a refresh token.

        If the expression returns any other value, PingFederate sets the lifetime of the persistent grant based on the per-client Persistent Grants Max Lifetime setting.

      • To set a static lifetime, select Text from the Source list and enter a static value in the Value field.

        This is suitable for testing purposes, or cases where the persistent grant lifetime must always be set to a specific value.

      As the HTTP Request context value is retrieved as a Java object rather than text, OGNL expressions are ideal to evaluate and return values.

    • Extended Client Metadata

      Values are returned from the client record.

    • LDAP/JDBC/Other

      Values are returned from your datastore, if used.

    • Expression

      If enabled, this option provides more complex mapping capabilities, such as transforming incoming values into different formats. All of the variables available for text entries are available for expressions.

    • No Mapping

      This option ignores the Value field.

    • Text

      You can enter text only, or mix text with references to the attributes returned from the adapter instance, using the ${attribute} syntax.

      You can also enter values from your datastore using the ${ds.attribute} syntax, where attribute is any of the datastore attributes you have selected.
