In order for one site user to be able to impersonate another site user, the user will need to have the following site group permissions:
- Can impersonate other users
- Can edit their own personal account info.
- Ability to view a list of users
The impersonate button is found next to each user in the list of site users which is found on the /settings page. The user will need the ability to edit their account information to get to the /settings page and the ability to view a list of users to access the impersonate button.
