Problem with Adobe Reader 10 and digital signature

Hi All,

we have a problem with digital signature on Adobe Form ( Adobe Livecycle designer with SFP transaction).

It's work fine, but when we open the pdf signed file with Acrobat Reader ( version 10.x.. or 9 etc ), there is a message "the Signature is not Valid" ( There have been changes made to this document that invalidate the signature. and other message ). The digital certificate is valid and it's uploaded into the system with Strust transaction. Additionally, the connection ADS ( SSL ) has been set with SM59 transaction.

Have you idea to resolve this problem ( sap note o patch for Acrobat Reader)?

Thanks regards
