How to export the list of users from AEM?

To manage the user and security purpose, we always need the list of available and active users in our system for analysis. Adobe Experience Manager(AEM) also have an in build user management section to manage the AEM user and make the things secure. In this article we will export or generate the list of available user from AEM in an excel file. To perform this activity we will use the ACS commons. ACS commons provide so many powerful tools, which is easy to use and easily plug-able on AEM, by installing ACS commons package.

Prerequisite:

ACS commons should be installed in your AEM instance. If you don't have latest ACS commons installed in your AEM instance, then you can easily and free download the ACS package from here and install the package in your AEM instance using package manager.

Now we will perform the following steps to export the user list from AEM.

Step 1: Open the URL <domain>/miscadmin#/etc/acs-commons/exporters

If you are running on your local machine then; e.g. http://localhost:4502/miscadmin#/etc/acs-commons/exporters

Go to Tools >> acs-commons >> Exporters from left side rail. Below is the screenshot of steps.

1. Click on the Exporter folder
2. Click on New >> New Page
3. Create a page with any title using the default selected template(User to CSV Exporter).
4. Click on create button.

This will create a new page under the exporter directory. Open the newly created page by double clicking on that page name.

Export User list in AEM

Step 2: Your Page will now look like this(below screenshot). From here you may add or remove the user profile properties, which you want to export and get appended in your exported CSV file.

Add Custom Property will let you add user properties (Relative path from the [rep:User] node). if you don't know the path and property name then you may refer the CRXDE-Lite to get the exact path and property name.(Below is the screenshot)

Custom user properties

Screenshot to get the property name from crx/de. e.g designation, familyName

User profile section in CRXDE

Step 3: Now Select the group membership the way which you want to export. Using Only Include Users by Group Membership option.

1. Direct Membership : Only the direct member of groups.
2. Indirect Membership: Only Indirect member of groups, means a group which is member of another group.
3. Direct and Indirect Membership: Both direct and indirect membership.

Only Include Users by Group Membership option

Step 4: Now select all those groups whose members and user you want to export using Filter by Group option.(Select none for all groups). 

Download User CSV Report

Step 5: After selecting the all groups click on the Download User CSV Report button to download the csv file.

You may also save the configuration for later use using the save configuration button.
