How can i change my infopath form to use what is called a ucdx connection file containing NTLM authentication credentials.   Can someone explain this to me?

I am assuming you want to use static NTLM credentials?

You have to go to your UDC library.

Go to the dropdown and use the Send To and download a copy.

I believe that by default there is no authentication in a UDC and it assume to pass windows credentials.

You need to add this to your text in the UDCx xml.
        <udc:UseExplicit CredentialType="NTLM">

This block is after the /udc:UpdateCommand and before /udc:ConnectionInfo elements.

Just add your username and password that you wish to use.

Ok, I got that part and I can see the data fields that I can select from when I created the data connection and then the form.  What do they mean by NTLM authentication credentials?  i did not see anywhere in this process that I had to add any authentication credentials.  I am getting an error when I publish this but was wondering if that is because of the credentials issue?
