As mentioned previously from the KBase, "All users who can log in to OKTA, will not get access to Site24x7. Rather, they should be invited by Super Admin or Admin, as only a Super Admin or Admin can determine the user roles".
This is because we don't know what user role (super admin, admin, operator, billingcontact etc) we have to set when logging in for the first time.
However, we will look into ways in which we can default to a role.
Regarding the connector, we will verify and get back.
