Hiya,
Can i restrict a user to not login to account manager page though he has admin permission in it? The admin permission is in order for him to view/modify the profile of that certain user under the created location. I have a backend user for the administration page and part of it is to view/modify the user under that created location.
You could remove the login form, then they won't be able to login at all. However, backend users are always able to login at any available login dialog box.
