But i have a problem with ldapmodify.
My ldapsearch gives me the  following result.

$ldapsearch -x  -b 'dc=ubm,dc=com,dc=edu' '
(objectclass=*)' 
version: 2

#
# filter: (objectclass=*)
# requesting: ALL

# ubm, dc=com, dc=edu
dn: dc=ubm,dc=com,dc=edu

After this i tried to modify the record using
ldapmodify.
It gives me the following error

ldap_modify: Undefined attribute type
        additional info: attribute description
contains inappropriate characters

I have listed the command below.


$ ldapmodify -x -v -D "cn=manager,dc=ubm,dc=com,dc=edu
" -W
 -f mod
ldap_initialize( <DEFAULT> )
Enter LDAP Password:
replace o :
replace o:
        My sys Ltd
modifying entry "cn=user,dc=ubm,dc=com,dc=edu"
ldap_modify: Undefined attribute type
        additional info: attribute description
contains inappropriate characters

ldif_record() = 17
$

My mod file looks this way


dn: cn=user,dc=ubm,dc=com,dc=edu
changetype: modify
replace: o
o: My sys Ltd


where is the error?
Could help pls.


Thanxs 
Lin s
