To allow the Warehouse Insight web service to work with NTLM, you just need to make one small change to the ‘web.config’ file (usually in C:\inetpub\Insight Works\WMDM). Open the web.config in Notepad and scroll about 3/4 of the way down, and you’ll see the <bindings> section as shown. All you’ll need to do is replace the highlighted ‘Windows’ with ‘Ntlm’. Note that ‘Ntlm’ is case sensitive, so must appear exactly as that. Save the web.config, and then in IIS go to the ApplicationPools and Restart the appPool that you are using for the chosen Web Service.

 

Making only a switch to allow for NTLM shouldn’t result in a prompt for a login, so the Login tab of the Configuration screen on the PDA should still be set to none.
