LdapMember#getOrganizationalUnit has been unused for a long time, therefore it is deprecated now. There is a No-Op-default method, so you do not need to implement it in your LdapMember implementations any longer. In the unlikely case that you use the method in your project code, please let us know, describe your usecase, and we will find a way to preserve the necessary functionality without using it ourselves.
