ldap adding new entery

["Sundaram Ramasamy" <sun@percipia.com>]

I have installed ldap in Redhat 8.0, then I followed this URL.

http://www.tldp.org/HOWTO/LDAP-Implementation-HOWTO/index.html

Then I put following schema into percipia.schema file and added into
sladp.conf file

http://www.tldp.org/HOWTO/LDAP-Implementation-HOWTO/files.html#FILE-SCHEMA


include         /etc/openldap/schema/core.schema
include         /etc/openldap/schema/cosine.schema
include         /etc/openldap/schema/inetorgperson.schema
include         /etc/openldap/schema/nis.schema
include         /etc/openldap/schema/redhat/rfc822-MailMember.schema
include         /etc/openldap/schema/redhat/autofs.schema
include         /etc/openldap/schema/redhat/kerberosobject.schema
include         /etc/openldap/schema/percipia.schema

I was able to add sample entry listed in that document.  Now I am trying to
add outlook address book data its giving me erorr

[root@rose work]# ldapadd -x  -D "cn=Manager,dc=percipia,dc=com" -w
secret -f o
utlook.ldif
adding new entry "ou=microsoftaddressbook,dc=percipia,dc=com"
