Studio does not include a Version Specifier ("version: 1") in the generated LDIF export
(see http://www.novell.com/coolsolutions/feature/5997.html -> LDIF Content Records)
E.g. the Novell LDAP classes for Java will not accept an LDIF that does not contain the Version Specifier.
Perhaps Studio could make this optional, e.g. by a setting on the Text formats preferences page:
[x] add Version Specifier
