We are migrating our infrastructure from Sun Solaris to AWS. So as a part of migration we need to do the transition from Sun Directory Server to OpenLDAP. 

I exported the user database in ldif file from Sun LDAP. Now I am trying to import the database in to OpenLDAP Server on Ubuntu which  I've installed in AWS. While importing the database I am getting a lots of error , because the sun schema for storing the users and openldap is totally different.

The issue  I'm currently stuck on is getting the data in the LDIF into a format that can be imported using slapadd/ldapadd

Any help would be appreciated 

Below are the details for Ubuntu Server and OpenLDAP

Server OS :

OpenLDAP Version :

slapd                           2.4.21-0ubuntu5.7                 OpenLDAP server (slapd)
