Teachers have access to the complete list of users for all groups. Exceptions are general groups such as “All” or “All parents”.

Parents are not able to see the user lists in automatically created parent groups created by Sdui. However, if teachers add parents to groups that they have created, the last names of the other members can be seen by the parents. 

Students have access to the members in student groups. Exceptions are general groups such as "all pupils".
