Unable to authenticate signature - AS2

Hello there,

I am able to send AS2 message to partner successfully. But partner is getting below error message when he receives the message. I am not sure where the problem is.

Can anyone shed some light on this?

Looks like you signed it and he doesn’t have the verification certificate.


Thanks for the quick reply. Are you saying that the public key and the CAs that we provided to partner are not configured properly on the partner software?


That would be my first guess - it looks like they did not configure a signature verification certificate.

I would assume that it would be similar to how we configure under Trading Networks Partner Profile “Verify” tab by loading client certificate.

Highly dependent on what they are using - but the concept is the same, yes.

Hi, We are using EDIINT AS2 Htpps. When partner is trying to send the Certificate, they are getting the following error: Message Disposition Notification Reporting-UA: webMethods Integration Server Original-Recipient: rfc822; Final-Recipient: rfc822; Original-Message-ID:ssss Disposition: automatic-action/MDN-sent-automatically; processed/error: authentication-failed MDN for - Message ID: ssss From: 111 To: 112 Received on: 2009-02-03 at 10:27:19 (EST) Status: processed/error: authentication-failed Comment: This is not a guarantee that the message has been completely processed or understood by the receiving translator… We are using only the partners Unsigned Public key certificate. I Do know that we need the partner CA certificate. But i am just wondering that any body worked on processing Unsigned Public certificates? If so, help is really appreciated. Thanks in advance, Capri_lak
