Maybe not really SharePoint question, but maybe someone faced this...
Signed in to SharePoint Online from O365 with MS account (X-Forms Authentication) with flag "Keep me signed out" from native C++ application (Internet Explorer WinInet).
Now any request to the SharePoint is performed without ask for authentication. Nothing helped:
- sending GET to https://login.microsoftonline.com/logout.srf
- sending GET to https://login.live.com/logout.srf
- clearing WinInet cookies with
InternetSetOptionW(nullptr, INTERNET_OPTION_END_BROWSER_SESSION, nullptr, 0)
- searching for stored credentials in Credential Manager
Does any one know what request to send for signing out?
