Shared users can't be edited in the application

Problem

When you try to edit a user in your application, you receive the following message:

This user administers multiple applications and can only be changed by themselves.

Older versions show the message Shared user can only be changed by himself/herself.

Cause

The user is a shared user who is an administrator in more than one application (the user has the _EditUsers privilege in several applications). Such users can only be edited by themselves, or by a Site Admin. The same applies to Site Admin users (This user is a site administrator and can only be changed by themselves.).

Shared users who only have _WebLogin in several applications, and shared tracker assets, can be edited by the administrators of each application.

Solution

Option #1

Use impersonation from Site Admin (Legacy) to log in as the user to the application, and then make the changes you want to do. In Applications > Search and Manage, click the icon next to the application, select the user and click Login.

Option #1.2

You can access the same option from the application view by navigating to Main Menu > Platform Settings > Manage Applications.

Hover over the application and click the Log in as user icon in the Actions column. Select the user and click Log in as user.

Note: you need the _UseImpersonatedLogin Site Admin privilege to log in as another user. Site Admin users cannot be impersonated. When you are done, log out and log in again with your own Site Admin user.

Option #2

Edit the user as a Site Admin: a Site Admin user with the Site Admin Users privilege can edit (and delete) shared users and Site Admin users directly, for example in Main Menu > Users & Access > Manage Users.
