In Footprints 11.x, there is a "Supervisor" field type in the address book that will convert the LDAP "Manager" attribute distinguished name data into the managers display name. This is the way the name appears in Active Directory, Organization, Manager field. The raw LDAP attribute is the full distinguished name data.
In Footprints Service Core 12, there is no field type available to make this conversion. When linking to the manager attribute, it shows the distinguished name data. Please provide this function in a future version.
