# Mapping an adapter instance

After extending your attribute contract, you can map adapter instances on the **Authentication Source Mapping** tab.

## Steps

1. For initial steps, see [Managing authentication source mappings](help_assertioncreationtasklet_idpadaptermappingstate.html).

2. On the **Authentication Source Mapping** tab, click **Map New Adapter Instance**.

3. On the **Adapter Instance** tab, select an adapter instance from the **Adapter Instance** drop-down list.

4. (Optional) If you want to customize one or more adapter settings for this connection alone, select the **Override Instance Settings** checkbox.

   |   |                                                                                                                                                                                                                                                                                              |
   | - | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
   |   | If you are editing a currently mapped adapter instance, you can toggle **Override Instance Settings**. Clearing it removes all previously overridden settings for this connection. Selecting it provides you the opportunity to customize adapter settings specifically for this connection. |

   |   |                                                                                                                                                                                                                                                                                                     |
   | - | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
   |   | Alternatively, you can create child adapter instances of a base adapter instance (with overrides) so that customized settings can be applied to several connections. For more information, see [Hierarchical plugin configurations](../introduction_to_pingfederate/pf_hierach_plugin_config.html). |

   ### Result:

   Selecting the **Override instance settings** box will add the **Override Instance** tab to the navigation bar. For more information, see [Overriding an IdP adapter instance](pf_overriding_idp_adapter_instance.html)

5. Click **Next**, and refer to the following topics to complete the configuration.
