Error receiving xml via HTTPS

[Former Member]

I am trying to get inbound HTTPS working on our system using certificate authentication rather than username/password. First off, yes I have searched the forums to great degree, and yes I have reviewed documents at help.sap.com (such as Configuring the SAP Web AS for Supporting SSL).

Outbound HTTPS is working just fine.

I have set up STRUST with SSL Server, SSL Client, and another identity for our customer. I have added all the certificates to the PSEs (perhaps I didn't add what I needed. This could be a source of error). I added an entry in table USREXTID with a user I created, mapping to the customer's certificate DN. I have restarted ICM, but still the customer gets a 401 authorization error.

Is anybody using inbound HTTPS with certificate authentication? Could you please assist me in setting up our system.

Please don't respond with remarks such as check this thread as I have probably already checked it and received no help in it. If it were helpful, I wouldn't be here right now. Please respond with real assistance. Thanks.

We kind of gave up on it for now. Our customer was able to finally get username/password working on their end (required an upgrade to their system).

In looking for some other information, I stumbled up on a t-code sicf. When you drill down through the path to xi/adapter_plain, go to its properties. In the Service Data tab, there is a selection for Logon Procedure. Ours is set to Standard. One of the options is Client Cert (SSL). I am wondering if we select that, or do Alternative Logon Order, if that will allow the certificate authentication to work.

Unfortunately, I have not had time as of recent to test this out, so it is sitting on my back burner for the next few months.

If you try it out and get it to work, please let me know.
