Unset Acquire Local Roles On Document Portal Type Configuration If Applicable
If the type of document should not acquire local roles from the
parent documents (and modules), uncheck the "Acquire Local Roles" on this portal type configuration.
If the security of sub-document is different, you usually don't want
to acquire all roles from the parent. For example, this is the case for Assignment
documents, a user can be assigned some person documents, but we don't want this
user to open assignment which are physically contained in this person.
