Trying to connect a Cognito form to a Sharepoint Foundation 2013 list, I get:
Cannot connect: invalid settings.
The Sharepoint site is using Forms-based authentication with a custom role/membership provider.
I have tried with FBA credentials as well as a Windows Auth account, and neither work.
I also tried changing the URL—using the top-level URL of the site collection as well as the direct URL to the list, plus a few other permutations, and none seemed to work.
Is connecting to a Sharepoint list not supported in this environment? What else would I do to troubleshoot connection problems?
