I trying to do this

 filter.and(new EqualsFilter("objectclass", "user")).and(new EqualsFilter("mail", username));
  return ldapTemplate.authenticate(DistinguishedName.EMPTY_PATH, filter.toString(), password);

Answer 1

LDAP 32 is like eDirectory -601 and AD’s (ah I forget the code).

Basically object not found. I wonder if the DN you provided to bind with is not correct? Since you are doing a search, and object not found in a search should really just return an empty search result.
