Error 401 Unauthorized on accessing Soap-Adapter

[Former Member]

Hi,

we have a connection established to our supplier. We send POs with the soap-Adapter over https and we receive an asynchronous xml-response on our soap-adapter. Everything works fine with http but with https our supplier gets an <i>401-unauthorized</i> on return when sending the response. They send the correct username and password. We also tried to put the username and password in the url like <i>.../MessageServlet?...&sap-username=USER&sap-password=PASS</i> but that had no effect. I guess this only works with plain http.

Any ideas why this error occures?

Thanks.

Oliver.

Hi,

I hope

<i>Check XIAPPLUSER is having this Role -SAP_XI_APPL_SERV_USER

• If the error is in XI Adapter, then your port entry should J2EE port 5<System no>

• If the error is in Adapter Engine

–then have a look into SAP note- 821026, Delete the Adapter Engine cache in transaction SXI_CACHE Goto --> Cache.

• May be wrong password for user XIISUSER

• May be wrong password for user XIAFUSER

– for this Check the Exchange Profile and transaction SU01, try to reset the password -Restart the J2EE Engine to activate changes in the Exchange Profile After doing this, you can restart the message</i>

Thank you but I already checked this out and everything is ok. They don't even reach our adapter engine.

Thanks for the answers.

We checked this note but the conditions are all satisfied in our scenario.

Our password always have capital letters.

Where can I delete the Adapter Engine Cache? I couldn't find anything like that. I can only refresh it but not delete it.

Thx, but I still could't find where the Adapter Engine Cache can be deleted. It's not mentioned there. Besides, we don't have the problem that it happens sometimes as it is mentioned in this note. This error always occurs. And we have no high traffic at all. It's on our test system.

Hi,

1) This might cause due to wrong permissions.

2)Try with this Login XIISUSER

3)Tcode SICF -> Default_host -> sap -> xi

( Check right password for the user id )

4) Check the note 764176

Hi,

I logged on with the user XIISUSER and called the TA SICF. And now which password do I have to check? I didn't find any user at this point.

Oliver

once you login into SICF then drill down upto this "Default_host -> sap -> xi"

then double click you will get screen with details at bootom you will find userid and password.

There is the point "Anonymous Logon Data" where I can enter a user. But there is no user. It's empty. Do I have to enter the XIISUSER right there?

Oliver,

sorry for this i was answering your dbout not sure doss was saying do it but where to find if you need to delete cache you need to go to SXI_CACHE T/c code then select GOTO->AdapterEngine cache. then you will have delte option their just click on delete it.

Hi Oliver,

The same problem is discussed in SAP Note 856597

The user authentication of the SOAP adapter is not part of the SOAP adapter but of the web container of the J2EE engine. The default authentication setting is defined in the web.xml descriptor file of the SOAP dapter web application. This setting may be modified from Visual Administrator with some restriction.
