Schema definitions: from Sun DS to OpenLDAP

[Silvio Verrecchia <silvio.verrecchia@infocamere.it>]

Hello gurus,

I'm migrating a Sun DS to Openldap and I've an highly personalized 
99user.ldif file with user defined objectclass and attributes 
(hundreds... :( :( )
Regarding personalized schema definitions, is there a way 
(script/batch/etc) to convert quickly and easly a Sun DS 99user.ldif 
file to the standard OpenLDAP schema files ?

Any suggestion is highly appreciated !

Thank you very much!

Silvano
