Making a web request to a web page which requires windows authentication

Question

I am trying to make a request to a web page using WebRequest class in .net. The url that I am trying to read requires Windows Authentication due to which I get an unauthoris

Answer 1

You should use Credentials property to pass the windows credentials to the web service.

If you wish to pass current windows user's credentials to the service then

request.Credentials = CredentialCache.DefaultCredentials;

should do the trick. Otherwise use NetworkCredential as follows:

request.Credentials = new NetworkCredential(user, pwd, domain);

Answer 2

I am trying to access a link A passing the windows credentials. Link A then redirects me to link B automatically but does not pass the windows credentials which I had supplied. Hence the error. I did request.AutoRedirect = false, and looped through every time I get location in the header i.e. I do my redirects manually each time passing the windows credentials.

This worked for me :)

Answer 3

Using VS2015, request.UseDefaultCredentials = true; works for me!

Answer 4

For authenticating to WebService, use DefaultNetworkCredentials instead of DefaultCredentials:

request.Credentials = CredentialCache.DefaultNetworkCredentials;
