Yes, it's possible to do this. But not possible using auth_bind.
You are going have to login using an administrator account, then do an
ldap search for the email address, then authenicate against it. Using
auth_bind requires you to know the username before you login.

Hi all!
Is it possible to authenticate against Active Directory, using the
whole e-mail address and not the user part (%n), so that if you support mutiple domains, all
users should authenticate with their e-mail addresses.I use auth_bind_userdn = DOMAIN \ %u but somehow the *mail* attribute of Active/LDAP should be employed.
thanks in advance Dimitrios Karapiperis
