Is it possible to restrict users to be in more than one group?

[joha0123]

Hi, in my application i have three groups (admins, clients, employees). The groups are disjunct. How can i make sure, that a user cannot be in the clients and employees group?

By adding them only in one group... I guess...

from documentaion of ion_auth

        # single group (by name)
        $group = 'gangstas';
        if (!$this->ion_auth->in_group($group))
        {
            $this->session->set_flashdata('message', 'You must be a gangsta to view this page');
            redirect('welcome/index');
        }

        # single group (by id)
        $group = 1;
        if (!$this->ion_auth->in_group($group))
        {
            $this->session->set_flashdata('message', 'You must be part of the group 1 to view this page');
            redirect('welcome/index');
        }

        # multiple groups (by name)
        $group = array('gangstas', 'hoodrats');
        if (!$this->ion_auth->in_group($group))
            $this->session->set_flashdata('message', 'You must be a gangsta OR a hoodrat to view this page');
            redirect('welcome/index');
        }

        # multiple groups (by id)
        $group = array(1, 2);
        if (!$this->ion_auth->in_group($group))
            $this->session->set_flashdata('message', 'You must be a part of group 1 or 2 to view this page');
            redirect('welcome/index');
        }

        # multiple groups (by id and name)
        $group = array('gangstas', 2);
        if (!$this->ion_auth->in_group($group))
            $this->session->set_flashdata('message', 'You must be a part of the gangstas or group 2');
            redirect('welcome/index');
        }

        # multiple groups (by id) and check if all exist
        $group = array(1, 2);
        if (!$this->ion_auth->in_group($group, false, true))
            $this->session->set_flashdata('message', 'You must be a part of group 1 and 2 to view this page');
            redirect('welcome/index');
        }
