It is not possible to remove those options using CSS. We can do the following simple java code for removing those tabs... The page which we need to edit is "/portal-trunk/portal-web/docroot/html/portlet/users_admin/edit_user.jsp".
List<String> identificationList = new ArrayList<String>();
for(String identificationItem : identificationSections){
identificationList.add(identificationItem);
System.out.println(identificationItem);
}
identificationList.remove("websites");
identificationList.remove("instant-messenger");
identificationList.remove("social-network");
identificationList.remove("sms");
identificationList.remove("open-id");
identificationSections = new String[identificationList.size()];
for(int i = 0; i < identificationList.size(); i++){
identificationSections[i] =identificationList.get(i);
}
Its easy to hide those links by using the simple java code written above.
