ldapadd error

[zhfei <zhfei@sdb.ac.cn>]

Hi everyone,
   I install the openldap-2.0.25 in my Redhat 7.2 box as root.
   After configuration,I start sldap:
# /usr/local/libexec/slapd -f /usr/local/etc/openldap/slapd.conf
# ps -el
...
040 S    0 2205      1    0 69  0  - 1740 rt_sig  ?     00:00:00 slapd
040 S    0 2206   2205 0 69  0  - 1740 do_pol ?     00:00:00 slapd
040 S    0 2207   2206 0 69  0  - 1740 rt_sel   ?     00:00:00 slapd
...
so,it runs well?
I write a test LDIF file as root ,named test.ldif:

dn: dc=beaver, dc=rd, dc=sdb, dc=ac, dc=cn
o:  CNIC
objectclass: top
objectclass: organization

Then I test ldapadd command as root:

# /usr/local/bin/ldapadd -h localhost -p 389 -D "dc=beaver, dc=rd, 
dc=sdb, dc=ac, dc=cn" \
> -w secret -f test.ldif
ldap_sasl_interactive_bind_s: No such attribute

What's mean?  Can anyone tell me?

The fllowing is sldap.conf content:
#
include        /usr/local/etc/openldap/schema/core.schema
pidfile         /usr/local/var/slapd.pid
argsfile       /usr/local/var/slapd.args
database     ldbm
suffix         "dc=beaver,dc=rd,dc=sdb,dc=ac,dc=cn"
rootdn        "cn=Manager,dc=beaver,dc=rd,dc=sdb,dc=ac,dc=cn"
#password is secret
rootpw        {MD5}Xr4ilOzQ4PCOq3aQ0qbuaQ==
directory    /usr/local/var/openldap-ldbm
index    objectClass    eq
#

Thanks in advance.
