Two References to the same table using FluentNHibernate

Question

I have one table which is, for example, User. Now, In my table Books, I need to map two user fields

public User Wants {get; set;}
public User Read {get; set;}

How to map this? (Older version of fluentnhibernate and automapping doesn't work in this case) Generally, answer needs to work with automapping, because all entities in application are using automapping.

I think it is straight-forward.

public class BookMap : ClassMap<Book>
{
    public BookMap()
    {

        /* all other mapping info */

        References<User>(x => x.Wants)
            .Class(typeof(User))
            /*.Not.Nullable() */
             .Nullable()
            .Column("WantsUserUUID")
            .Index("IX_Book_WantsUserUUID")
            .Cascade.SaveUpdate()
            ;
        ;

        References<User>(x => x.Read )
            .Class(typeof(User))
            /*.Not.Nullable() */
             .Nullable()
            .Column("ReadUserUUID")
            .Index("IX_Book_ReadUserUUID")
            .Cascade.SaveUpdate()
            ;
        ;
