To avoid creating a new user from scratch, you can duplicate an existing one and modify the authentication information as required.
To duplicate a user:
On the Users page, select the user you want to duplicate.
On the toolbar, click Duplicate and modify the information on the panel to the right.
Click Save at the bottom right corner to validate the operation or click Cancel to cancel it.
If you click on any of the users in the list before finalizing the creation or modification of the current user, a dialog box prompts you to save the parameters in the configuration panel before switching to another user. Click Cancel to return to the configuration panel and save the parameters.
