javascript - 调用 Web 服务时的 ASP.NET Windows 身份验证框

Question

Got a very strange issue, never seen it before. Basically in the admin section of our website, a user attempts to edit something by clicking a button.

This button attempts to call a webservice (via jquery, which the page will then use to show an edit form in shadowbox).

However the user informs me that instead of the form popping up as usual it is blank for a few seconds. Then this pops up:

Any ideas? The webservice is in the admin section, which requires the user to be in a role (which the user is, otherwise they would never get to the point of being able to click the edit button).

Answer 1

This is normal if your web service is located on a different machine as your web server.

If the two machines are on the same domain, then the browser will attempt to use the default network credentials that has been cached.

This dialog will also pop up if the default credentials used to access the web server (which could be anonymous) does not have access to the resource (folder) where the web service is running. The pop up gives the user an opportunity to enter another set of credentials.
