When you delete an unauthenticated access user, you must also remove the application pool entitlements for the user.
Note: If you delete an unauthenticated access user and if there is an existing client session for that AD user, then you must restart the client session to make the changes take effect.
- In Horizon Console, select Users and Groups.
- On the Unauthenticated Access tab, select the user and click Delete.
- Click OK.
