I want to add an entry with Chinese ( GB ) in the firstname, sn and cn attributes. However, openldap refuse to add it saying "invalid per syntax". I think it is because I have defined firstname as IA5String? If so, how can I resolve this? when I used the old version of ldapserv ( ldap v2 based ), the attributes are automatically base64 encoded by the server. Is this feature available in OpenLdap 2.x?
