How can I use many-to-one without foreign-key

How can I use many-to-one with unique column, that column is not foreign-key. Here is a code,
<many-to-one name="department" column="gdm_id" unique="false" class="com.greenlight.testxpert.persistence.Department" cascade="none" not-null="false" foreign-key="FK_USR_DEPT" />
Now If I don't have "gdm_id" as a foreign-key, it only a unique column. Then how could I map to Department unique column.
Thanks & Regards,

I don't see the use of foreign-key in many-to-one in this from the Hibernate docs pages.
It seems it is just using some column not a specific FK field.
