Wrong. The grammar in RFC2849 quite explicitly states:
ldif-file = ldif-content / ldif-changes
ldif-content = version-spec 1*(1*SEP ldif-attrval-record)
ldif-changes = version-spec 1*(1*SEP ldif-change-record)
ldif-attrval-record = dn-spec SEP 1*attrval-spec
ldif-change-record = dn-spec SEP *control changerecord
That means an LDIF file must start with 0 or 1 version-specs, then a dn-spec.
And, all records must end with LF or CR/LF.

Apparently it Net::LDAP::LDIF is broken. Since that is not a piece of OpenLDAP
Software I don't see what we can do about it. This ITS will be closed. Contact
the author of Net::LDAP::LDIF to pursue this further.
