Yes. The exact method it uses to generate the DN may vary from module to
module. My module would first do a search of uid=dan to find an entry
that matches. (If the search returned more than one entry, it would deny
access). Then it fetches the DN corresponding to that entry, and
attempts a bind with that DN and "mypassword".

Yes, although hash and compare is the minimum it will do. It is possible
to implement other site-specific policies that would do more than that
to determine if access is allowed.
