You need user_filter and pass_filter to recognize also the email addresses
IMHO.

Mine look like:
pass_filter = (&(objectClass=suseMailRecipient)(|(alias=%n)(uid=%n)))
user_filter = (&(objectClass=suseMailRecipient)(|(alias=%n)(uid=%n)))

You have to adapt to your own ldap attributes and use the correct variable
(%n) to match your usecase. My users can login (and receive mails) via all
of their aliases, primary address (part of the alias set) or their username.
