We've recently upgraded our XI 3.0 system to PI 7.1EHP1, and since this upgrade we're having problems with the Seeburger AS2 adapter (2.1.3). The outbound message (signed and encrypted) to our other party is fine, but the acknowledgment gives an error in the message overview:
Error while parsing AS2 message: AUTHENTICATION_ERROR #
We've checked the certificates in the NWA store, and they are all fine. We've also checked the user for the AS2 adapter in the connection factory, and these settings are also fine. The sender agreement contains a reference to the right certificates in the store.
Has anybody run into the same problem, and does anybody know how to fix it? There are some posts on SDN about this, but they all point towards the certificates (which seem to be fine) and don't offer any further explanation of the problem and a possible solution.
Kind regards, Wilbert
