External ABAP call to Sharepoint using SAML and OAuth

[Greg-55]

I'm trying to make a REST call to a SharePoint system based on NTLM using either CL_HTTP_CLIENT or CL_REST_HTTP_CLIENT by authenticating via a SAML token. Does anyone know if this is possible or know of an example?

Hi Greg,

I have to fullfill a similar requirement. Did you succeed with your implementation? Could you give me some hints?

Hi Guys,

did you find a solution?

I got very similar requirements 😕

Hi Markus,

we finally implemented a SOAP consumer client but there are some problems to overcome:

1. our BW box is running on Linux and there was no easy way to get NTLM implemented

2. sharepoint offers different ways: REST based and SOAP based
the REST service (via listdata.svc) returns not the internal (and stable) column names but the descriptions

SOAP returns some sort XML which I was not able to parse with methods of class  /iwfnd/cl_sutil_odata_mapper.

The final solution looks roughly like this:

-create a consumer proxy

-call get_list_items service of sharepoint

-use class / interface if_ixml to create DOM object based on the XML stream

-parse the DOM object in order to convert into ABAP like structure

Best Regards, Thomas

Thank you Thomas,

I will give it a try, by the way we are also using Linux 🙂

Hi Thomas,

I created a Consumer Proxy, but I can't find a way to set the auth. method to SAML? I think it's not as easy as I'm thinking

May you have another hint for me

Hi Markus,

sorry for my late reply

in our implementation we changed the authentication method from NTLM to basic authentication as our os (linux) does not support NTLM without implementing additional linux packages.

please talk to your sharepoint admin, maybe there are both ways at the same time possible
