SSL invalid certificate, may need to cross-certify

We have an WebService and provide WSDL to our customers. All customers (there are hundreds) have no problem with our service except one who is using Lotus Notes. When their code trying to connect to our service the issue is thrown back. Here is a log.

I tried to import certificate to Notes JVM (cacerts). Did not help. I tried to disable veritifcation of certificate - did not help as well.

Certificate is GlobalSign

Lotus Notes 9.x. I'm using Java Agent to test WSDL.

Any idea what I have to do?

Solution

So the main error is this.

SSL invalid certificate, may need to cross-certify.

In order for Notes to correctly recognise the SSL certificate you also need to ensure that the whole SSL chain is imported as well. On top of this it has to be cross certified with your organisations certificate (or the users personal certificate).

The following details how to do this for the server for R9.

It should be somewhat similar process for the local client. You open the personal NAB and go to the advanced->certificates view.
