LDAP property mapping duplicate key

**Describe your question/**
I created a ldap property mapping for a custom attribute "myattribute". The attribute can exist multiple times for one user with different values. When testing the mapping I get returned the correct value if the attribute exists once, otherwise I get `Value must be a dictionary, and not have any duplicate keys.`. Is it possible to map duplicate values to an array and assign that to a attribute of the user?
