Adobe IMS Authentication and Admin Console Support for AEM Managed Services adobe-ims-authentication-and-admin-console-support-for-aem-managed-services

Introduction introduction

AEM 6.4.3.0 introduces Admin Console support for AEM instances and Adobe IMS(Identity Management System) based authentication for AEM Managed Services customers.

AEM onboarding to the Admin Console will allow AEM Managed Services customers to manage all Experience Cloud users in one console. Users and Groups can be assigned to product profiles associated with AEM instances, allowing them to log in to a specific instance.

Architecture architecture

IMS Authentication works by using the OAuth protocol between AEM and the Adobe IMS endpoint. Once a user has been added to IMS and has an Adobe Identity, they can log in to AEM Managed Services instances using IMS credentials.

The user login flow is shown below, the user will be redirected to IMS and optionally to the customer IDP for SSO validation and then redirected back to AEM.

How To Set Up how-to-set-up

Onboarding Organizations to Admin Console onboarding-organizations-to-admin-console

The customer onboarding to Admin Console is a pre-requisite to using Adobe IMS for AEM authentication.

As the first step, customers should have an Organization provisioned in Adobe IMS. Adobe Enterprise customers are represented as IMS Organizations in the Adobe Admin Console.

AEM Managed Services customers should already have an organization provisioned, and as part of the IMS provisioning, the customer instances will be made available in the Admin Console for managing user entitlements and access.

The move to IMS for user authentication will be a joint effort between AMS and customers, with each having their workflows to complete.

Once a customer exists as an IMS Organization and AMS is done with provisioning the customer for IMS, this is the summary of the configuration workflows required:

Onboarding Users to the Admin Console onboarding-users-to-the-admin-console

There are three ways to onboard users depending on the size of the customer and their preference:

Manual Addition through Admin Console UI manual-addition-through-admin-console-ui

Users and Groups can be manually created in the Admin Console UI. This method can be used if they do not have a large number of users to manage. For example, a number of less than 50 AEM users.

Users can also be manually created if the customer is already using this method for administering other Adobe products like Analytics, Target or Creative Cloud applications.

File Upload in the Admin Console UI file-upload-in-the-admin-console-ui

For easy handling of user creation, a CSV file can be uploaded for adding users in bulk:

User Sync Tool user-sync-tool

The User Sync Tool (UST in short) enables enterprise customers to create or manage Adobe users utilizing Active Directory or other tested OpenLDAP directory services. The target users are IT Identity Administrators (Enterprise Directory and System Admins) who will be able to install and configure the tool. The open source tool is customizable so that customers can have a developer modify it to suit their own particular requirements.

When User Sync runs, it fetches a list of users from the organization’s Active Directory (or any other compatible data source) and compares it with the list of users within the Admin Console. It then calls the Adobe User Management API so that the Admin Console is synchronized with the organization’s directory. The change flow is entirely one-way; any edits made in the Admin Console do not get pushed out to the directory.

The tool allows the system admin to map user groups in the customer’s directory with product configuration and user groups in the Admin Console, the new UST version also allows dynamic creation of user groups in the Admin Console.

To set up User Sync, the organization needs to create a set of credentials in the same way they would use the User Management API.

User Sync is distributed through the Adobe Github repository at this location:

https://github.com/adobe-apiplatform/user-sync.py/releases/latest

Note that a pre-release version 2.4RC1 is available with dynamic group creation support and can be found here: https://github.com/adobe-apiplatform/user-sync.py/releases/tag/v2.4rc1

The major features for this release are the ability to dynamically map new LDAP groups for user membership in the Admin Console, as well as dynamic user group creation.

More information about the new group features can be found here:

How to Use how-to-use

Managing Products and User Access in Admin Console managing-products-and-user-access-in-admin-console

When the customer Product Administrator logs in to Admin Console, they will see multiple instances of the AEM Managed Services Product Context as shown below:

In this example, the org AEM-MS-Onboard has 32 instances spanning different topologies and environments like Stage, Prod, etc.

The instance details can be checked to identify the instance:

Under each Product Context instance, there will be an associated Product Profile. This product profile is used for assigning access to users and groups.

Any users and groups added under this product profile will be able to login to that instance as shown in the example below:

Logging into AEM logging-into-aem

Local Admin Login local-admin-login

AEM can continue to support local logins for Admin users, as the login screen has an option to log in locally:

IMS Based Login ims-based-login

For other users, the IMS based login can be used once IMS is configured on the instance. The user will first click on the Sign in with Adobe button as shown below:

They will then be redirected to the IMS login screen and enter their credentials:

If a federated IDP is configured during initial Admin Console setup, then the user will be redirected to the customer IDP for SSO.

The IDP is Okta in the below example:

After authentication is complete, the user will be redirected back to AEM and logged in:

Migrating Existing Users migrating-existing-users

For existing AEM instances that are using another method of Authentication and are now being migrated to IMS, there needs to be a migration step.

Existing users in the AEM repository( sourced locally, via LDAP or SAML) can be migrated to point to IMS as the IDP using the User Migration Utility.

This utility will be run by your AMS team as part of IMS provisioning.

Managing Permissions and ACLs in AEM managing-permissions-and-acls-in-aem

Access control and permissions will continue to be managed in AEM, this can be achieved using separation of User Groups coming from IMS( e.g. AEM-GRP-008 in the example below) and local groups where the permissions and access control is defined. The user groups that are synced from IMS can be assigned to local groups and inherit the permissions.

In the example below, we are adding synced groups to the local Dam_Users group as an example.

Here, a user has also been assigned to a few groups in the Admin Console. ( Please note that the users and groups can be synced from LDAP using the user sync tool or created locally, please see the section Onboarding Users to the Admin Console above).

The user is part of the following Groups in IMS:

When the user logs in, their Group Memberships are synced, as shown below:

In AEM, the user groups synced from IMS can be added as members to existing local groups, e.g. DAM Users.

As shown below, the group AEM-GRP_008 inherits the Permissions and Privileges of DAM Users. This is an effective way of managing permissions for synced groups and is commonly used in LDAP based Authentication methods as well.
