Which administration tool would you use to enable a user to access the system on behalf of another?

To enable a user to access the system on behalf of another, you would use a tool known as "delegation". Here are the steps:

1. Identify the system: The first step is to identify the system where you want to enable user access. This could be a computer network, a software application, or a web platform.

2. Choose the right tool: Depending on the system, the administration tool you use may vary. For instance, in a Windows environment, you might use Active Directory. In a Linux environment, you might use the sudo command. For a web application, you might use the application's built-in user management tools.

3. Set up delegation: Once you've chosen the right tool, you'll need to set up delegation. This usually involves going into the tool's settings or configuration options and specifying which user (the "delegate") should be allowed to access the system on behalf of another user (the "delegator").

4. Test the delegation: After setting up delegation, it's important to test it to make sure it works as expected. This might involve logging in as the delegate and trying to perform actions on behalf of the delegator.

5. Monitor and adjust as necessary: Finally, after setting up and testing delegation, you should continue to monitor it to ensure it continues to work as expected. If any issues arise, you may need to adjust the delegation settings or troubleshoot any problems.
