<p>I am  trying to solve below scenario Using acl spring security </p>

<p>We got a scenario to share the  students result to group of teachers.In this scenario when a teacher login he can see the result only if teacher have read permission on Result object.If we need to share the result to group of teachers having 10 members in the group with read permission we need to give 10 entires in ACL_Entry table .This would be complicated as entries will increase with increase in group members and increase in permissions.Is there any other way such that if i share the result to group there will only one acl entry with group having read permission on result object with which automatically the teachers should get permission to read the object.Can you also explain with example how the schema would be.</p>

<p>Please help</p>
