SOAP Asynch Message Giving HTTP 401 Unauthorized error

[Former Member]

Hi experts,

<Br>

We are sending ORDERS IDOC Asynchronously from ECC To XI and XI is sending it to Vendor using SOAP.

This interface was working OK and now we had HTTP 401 error. Checked URL,Username and password to the Vendor. It looks OK. It is working OK if I try it in browser.

</br>

I tried to refresh the object by changing values and reactivating,did cache refresh..Still didn't work.When I try to check for the problem found J2EE_GUEST user was locked.Same was unlocked and tried again.

</BR>

<BR>

This IDOC is requesting for acknowledgement( trying to suppress ack by running IDX_NOALE).

But now I need to reprocess these failed messages.I was trying in different ways and it is not going thru.

Any pointers are really appreciated.

Problem resolved after the above.

Hi Ramesh,

If your 401 problem is solved and you want to reprocess failed messages than you can resend it through Runtime Workbench

MessageMonitoring->Adapter Engine-> Find your failed messages and resend

Thanks for all of you..

I am talking to Vendor. They are using IIS Server to host their WebService.When I was resending they see 401 with sub status codes 2 and 5.

<B>

These sub statuses codes for HTTP 401 means

<B >2 Access is denied due to server configuration favoring an alternate authentication method

<B> 5 Authorization failed by an ISAPI/CGI application.

<B> Vendor is trying to see if they need to make modification in server configuration.

<B> If you have any ideas how to fix these in IIS server please post there.

The problem is in IIS server Configuration. Vendor changed their logging process so that user login needs domain name inforont of it. like domain\username.

made this change and Vendor made some changes at their side (not sure what change). It is working now.

Thanks to all of you for your helpful answers.

Hi Ramesh,

Have a look at dis note 821026

So, your issue is resending failed messages, or HTTP 401 Unauthorized ?

[Former Member]

Can you run a sniffer tool & see the actual reason for 401 unauthorized error? 6172 weblog: Troubleshooting SOAP, HTTP and Mail Adapter Scenarios with TCPGateway by Stefan Grube...

Generally, 401 unauthorized is when the target system rejects the request... Also, What type of authentication does the target webservice have.?? B'cos i ran into a similar problem with Ms-Webservice. (they were using NTLM authentication). It works from a browser but not from PI. So we installed SOAP-AXIS adapter to support NTLM based authentication.
