InCommon Federation provides federated identities for academic communities. As an identity administrator for an educational institution that is a member of InCommon Federation, you can configure your enterprise to accept login for access to Adobe applications using an InCommon Federated ID.

When signing in with a Federated ID, the user's Identity Provider (IdP) authenticates the user's identity, and Adobe grants authorization for its services to the authenticated user. To provide authorization, Adobe creates an internal Adobe ID that corresponds to the InCommon Federated ID.

Each IdP stores identity information differently, which means that you must create a mapping between the specific fields that your IdP uses, and the fields that are required for the corresponding Adobe ID. The mapping must go both ways. You must configure your Adobe organization with your IdP contact and mapping information, and you must configure your IdP with contact and mapping information for your Adobe organization.

Prerequisites

To complete the configuration process, you must be an identity administrator with appropriate access privileges for both your Adobe organization account and your IdP account. You must have the following:

  • A working SAML 2.0 compliant IdP. InCommon Federation members typically use Shibboleth 2.x or 3.x as their IdP, but that is not required.
  • Administrative access to both the Adobe Admin Console and the InCommon Federation Manager.
  • Administrative access to your IdP metadata.
  • An approved domain claim for your Adobe organization account.

Mapping between Adobe and InCommon Federated IDs

For your organization to allow SSO access to Adobe applications through your InCommon Federated IDs, you must do two things:

  • Use the Adobe Admin Console to configure your organization with the security details of the IdP that you use to authenticate your InCommon Federation IDs.
  • Use the InCommon Federation Manager to configure a Service Provider entry for Adobe connections.

Configure your IdP information in Adobe Admin Console

To Configure Single Sign-On for your domain, enter the required information using the Set Up Domain wizard in the Adobe Admin Console.

Set Up Domain

You must fill in these fields to enable Adobe to connect to your service provider and allow users to log in with their InCommon Federated IDs.

  • IDP Certificate: The PEM-format certificate in your IdP metadata. The file must have the extension .crt
  • IDP binding: HTTP-POST or HTTP-REDIRECT.
  • User login setting: Choose whether users log in with an email address or a simple username.
  • IDP issuer: The entity ID of your IdP.
  • IDP Login URL: The SAML login endpoint, as required for the Binding you specify.

To access the metadata file for the new service provider, click Download Metadata. Use this file to configure your SAML integration with the Identity Provider. Your Identity Provider requires this file to enable Single Sign-On.

Configure an Adobe Service Provider entry for your IdP

A connection to Adobe requires a custom Service Provider in the InCommon Federation Manager. The Service Provider entry maps identity information between the Adobe Federated ID format and the InCommon Federated ID format used by your IdP. You find the Adobe values in the service-provider metadata file you downloaded from Admin Console.

To create a Service Provider entry, use the following steps.

  1. In the InCommon Federation Manager UI, choose New Service Provider.

  2. Fill in the Entity ID from the entityID field in your Adobe metadata.

    new
  3. Under User Interface Elements and Requested Attributes, set SP Display Name to a name that you will easily recognize.

    v2_SP_display_name

    To fill in Requested Attributes, you must first configure the IdP for the custom attributes that Adobe requires as described below. Skip it for now.

  4. Under Assertion Consumer Service, fill in the corresponding values from the Adobe metadata. For Location URL, use the SAML HTTP-POST binding value.

    Assertion_Consumer_Service
  5. Single Logout Services are not currently supported. Leave blank.

  6. Enter appropriate Contacts information.

    contacts

IdP Configuration

The Adobe Service Provider requires that the IdP provide three custom attributes with these specific case-sensitive names:

  • FirstName: Equivalent of `sn` (`surname`) InCommon attribute (urn:oid:2.5.4.4)
  • LastName: Equivalent of `givenname` InCommon attribute (urn:oid:2.5.4.42)
  • Email: Equivalent of `mail` InCommon attribute (urn:oid:0.9.2342.19200300.100.1.3)

As the corresponding InCommon attributes do not use the same names, you must configure your IdP to map the values and send them as custom attributes. If you use Shibboleth as your IdP, see their documentation for configuring custom attributes:

In addition to these custom attributes, you must configure the Subject attribute's NameId field to contain the value of the user's login username or email (as configured in the Adobe Admin Console). If you use Shibboleth as your IdP, see their documentation for configuring the NameIdfield:
