I'm using iText 5.5.3 to sign PDF documents. I need these documents to be timestamped and LTV-enabled. I followed the instructions and used the addLtv method (code sample 5.9, page 137 in the Lowagie's white paper). I get a PDF with 2 signatures, which is normal: the first is my own signature, the second is the document-level timestamp.

However, Acrobat tells me my signature is LTV enabled, but the timestamp signature is not :

This is because the revocation info of the timestamp certificate is not embedded in the document :

[Missing revocation info 1 http://img15.hostingpics.net/pics/491507so2a.jpg](http://img15.hostingpics.net/pics/491507so2a.jpg)

[Missing revocation info 2 http://img15.hostingpics.net/pics/312720so2b.jpg](http://img15.hostingpics.net/pics/312720so2b.jpg)

From my understanding, the addLtv method **should** get all revocation information needed and embed it in the document. Is that correct, or do I have to "manually" get and embed these informations ?
