[Samba] smbldap-populate

[mario]

Anyone familiar with ldap tools smbldap-tools ? 

I am having a problem populating the LDAP directory with samba schema ... 

When I run smbldap-populate I get error :

ERROR : failed to add entry : objectclass : value #4 invalid per syntax at /usr/local/sbin/smbldap-populate line 495 
<GEN1> Line 7

I am using openldap that comes with Zimbra so there is already Zimbra schema there . 

Anyone know what this error could be about . Would it help if upload my schema files
and the smbldap-populate script ?
