openldap default username/password?

Hi,

I'm trying to configure openldap using slapd.d style configuration, however command:

#ldapadd -vxh localhost -D cn=admin,cn=config -w "" -f /usr/local/conf/shared/openldap/init-config.ldif

fails with error

ldap_initialize( ldap://localhost ) ldap_bind: Server is unwilling to perform (53) additional info: unauthenticated bind (DN with no password) disallowed

#ldapadd -vxh localhost -f /usr/local/conf/shared/openldap/init-config.ldif

fails with error

ldap_initialize( ldap://localhost ) add objectClass: olcGlobal add olcLogFile: /var/log/openldap/openldap.log add olcLogLevel: -1 adding new entry "cn=config" ldap_add: Strong(er) authentication required (8) additional info: modifications require authentication

any ideas?
