If you export the OpenLDAP sdchema into an LDIF file you have to filter out 
the entries that do not belong to your schema.

It is much easier to change your schema file into an LDIF:
1) bring each entry onto one line
2) remove the empty lines between the entries
3) Replace the first word of each entry:
   s/^attributetype/attributetypes:/i  and s/^objectclass/objectclasses:/i
4) Insert the 4 lines
	
	   dn: IPLANET-SCHEMA-DN
	   changetype: modify
	   add: attributetypes
   (including the empty first line ;-) before the list of lines starting with
   "attributetypes:". Do not leave an empty line between these four lines
   and the first line starting with "attributetypes:"
   Of course the string IPLANET-SCHEMA-DN has to be replaced by 
   the DN of the iPlanet schema (maybe cn=schema as in OpenLDAP)
   Do the equivalent with objectclasses
5) Insert the line
	version: 1
   at the top of the file
6) ldapmodify the result to the iPlanet server
