Hi,

I have a scenario to write the payload of the SOAP Message to an intranet URL on HTTP.  So my scenario is SOAP Sender and HTTP_AEE Receiver adapter. We are PI 7.4 ( single Stack ) SP level 7.

I have the following error on PI in the HTTP_AEE receiver adapter.  We use HTTP protocol with anonymous authentication or user id password on the INTRANET. Either ways we have the same issue.  We have tested our Intranet HTTP url using POSTMAN and its work fine. There are several interfaces which are going out of PI to internet and they are all working fine. Our PI system is able to communicate to Intern

Authentication fails

I did try changing the SPECIFY CONTENT Type as "text/xml". However I still have the same issue.

What strange is in the LOGS we see the error "Credentials cannot be used for NTLM authentication: com.sap.httpclient.auth.UserPassCredentials".
