I'd recommend you take the presented username and *search* for the DN.
Something like this might do the trick. The inside ldapdn lookup
searches for the user's DN. The outer lookup performs the authentication
with that dn:

ldap_plain: driver = plaintext
   public_name = PLAIN
   server_prompts = "LDAP Username:: : LDAP Password::"
   server_condition = \
        ${\
           lookup ldap { \
               user="${lookup ldapdn {ldaps:///BASEDN?dn?sub?(mail=${quote_ldap:$2})}}" \
               pass="$3" \
               ldaps:///BASEDN?uid?sub?(mail=${quote_ldap:$2}) \
         }{yes}fail \
    }
   server_set_id = $2


You'll have to test this.
