#SharePoint #Call Web Service I am trying to invoke SharePoint Web Services by making use of Call Web Service Smart Service. Even after providing the correct WSDL, username, password and domain (I have tried it with 3 different values namely NTML, IAM and blank value (null)). The error we are experiencing at the moment is as follows (Attached the screen print):

The WSDL requires authentication. Please provide valid credentials (APNX-1-4045-006)

I have seen previous posts on the same lines and as per my understanding, they are not yet or partially resolved. I saw some posts talking about the domain and their compatibility with Appian. Would someone here please be able to guide in a right direction?

Appian 16.1 and SharePoint 2013 are the environments being used.

Thanks in advance.

I did some digging and found that the Call Web Service nodes do not support NTLM v2 authentication. Can you confirm that your Sharepoint server does not require v2? I believe you can accomplish this through the following:

1. In the SharePoint (Windows Server) server click "Start" and type "Local Security Policy"
2. Expand the "Security Settings" - "Local Policies" - "Security Options" folder from the left navigation menu
3. Scroll down until you find the following setting:
----> Network security: Minimum session security for NTLM SSP based (including secure RPC) servers
4. Right click on this setting and select "Properties"
5. **DISABLE*** the following option
----> Require NTLMv2 session security
Cancel
