[Pades ltv] LTV verification not readed

Hi

I am developinf a service that sign qith pades-ltv structure.

This structure is quite simple, it doesn't have neither VRI nor CRL, it only has OCSPs and Certs into DSS.

I have marked and signed a file, added a ltv structure at the end but when i submit this pdf to adober reader 11 it doesn'see the ltv, it says that the signature is ok but doesn't mention the ltv

the file is here.

Probably i missed something but i dont figure out exactly the reason.

Thanks
