Unable to authenticate over NTLM to consume WebService

,
1

Hello Folks,

I am trying to consume a soap ws hosted on IIS with NTLM authentication from my localhost Integration Server (IS)
From the same machine which my IS (windows) I can set soap UI and call it with no errors. However, I m still not sure how to do the same with Integration Server, using designer and its generated consumer based on WSDL.
I am not running IS as service on my windows so, not sure if WmWin32 and ntlm:rg are useful for development purpose.

What I am getting so far is :

HTTP 401 (not authorized) with the stacktrace below:

Of course as a Java Developer, I understand what ā€œjava.lang.NoClassDefFoundErrorā€ means, but have no Idea how to fix it. I wonder if you guys can support me.

Your wM version? Create a flow service wrapper and inovke the consumer WSD connector in it.

AFAIK you must activate the Integrated Windows Authentication via WmWin32 package. Refer IS Administration Guide ā€œUsing NTLM Authentication and Integrated Windows Authentication with Integration Serverā€

In addition to this, go to \integrationserver\instances\default\packages\wmwin32\code\libs\

Ntlm.dll

Ntlm64.dll

Wmeventlog.dll

Wmeventlog64.dll

Copying the Ntlm dlls to the Microsoft Windows system directory, e.g.

C:\Windows\System32\

Restart IS
Call ntml:reg service in the WmWin32 package

And if you still have the same error try the below setting:
Change wrapper.conf to include path to DLLs
wrapper.java.library.path.4=<INSTALL_DIR>\IntegrationServer\instances\default\packages\WmWin32\code\libs

Hello M@he$h

Well done, it works ! Thank you so much.

I am evaluating the trial 9.12 IS version, just in case!

Thank you!

Hi Mahesh,

I have an interface calling from v9.5 IS to target using SOAP HTTP url and the providers asked us to use NTLM credentials while calling their system.

  1. I tried from soap ui by calling their wsdl directly with the provided credentials (domain name, username & password). It is working
  2. I tried from my code and pass the credentials at
    webservice connector ā†’ auth ā†’ user(domainname\username)
    webservice connector ā†’ auth ā†’ transport ā†’ pass(password)
    Here Iā€™m getting " Authorization error"
  3. I gone through the empower forums and somewhere mentioned as IS_9.5_SP1_Win32_Fix1 needs to be installed to resolve Authorization error and I have installed this fix but issue remains same
  4. I tried as per your suggestion mentioned above
  • wrapper.java.library.path.5=<INSTALL_DIR>\IntegrationServer\instances\default\packages\WmWin32\code\libs
  • Enabled WmWin32 package and called ntml:reg service in the WmWin32 package
    but still Iā€™m getting same authorization error.

Any further suggestions will be a great helpā€¦

Thanks,
Venkat .

If the above resolution steps does not fix your issue I would suggest you to contact SAG with details. Kindly update if you hear a fix from them.

Hi,
Now Authorization error resolved by adding the Authorization type as NTLM at connector ā€œtransportHeadersā€ level but getting the below error.

com.wm.app.b2b.server.ServiceException: org.apache.axis2.AxisFault: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character ā€˜"ā€™ (code 34) in DOCTYPE declaration; expected a space between public and system identifiers
at [row,col {unknown-source}]: [1,50]

Please let me know if you have any clue on this
