RadCaptcha image not showing

[JJ]

I use RadCaptcha on a email page that does not require the user to login to the site to finish - used <allow users="*"/> in web.config for this email.aspx location.

But the rest of the pages on site need the user to login - put under secured direct.
 
When I go to the email.aspx, I can see everything on the email pages, except the RadCaptcha image.

How I resove this problem?

Thanks!

Hi Jessie,

"Forms" authentication requires a registered user to be logged-in to the system in order to access a certain resource or a given page. If the user is not logged-in and tries to access a resource that requires a log-in (such as the RadCaptcha httpHandler in your case), he/she is redirected to the Login page. That is why the image is not shown, because it requires log-in.

To solve this problem you should use the <location> Element to specify different authentication settings for the RadCaptcha httpHandler. Please use similar code for your application as the one shown below, and if you have any problems, please send us a sample project that demonstrates the issue. We would be glad to help.

1.

<location path="Users_Management/Pages/CreateUser">
    <system.web>
      <authentication mode="None"/>
    </system.web>
</location>

<location path="Telerik.Web.UI.WebResource.axd">
  <system.web>
    <authentication mode="None"></authentication>
  </system.web>
</location>

or
2.

<location path="Users_Management/Pages/CreateUser">
    <system.web>
      <authorization>
          <allow users="*"/>
      </authorization>
    </system.web>
</location>

<location path="Telerik.Web.UI.WebResource.axd">
  <system.web>
    <authorization>
      <allow users="*"/>
    </authorization>
  </system.web>
</location>

Hi Prakash,

I would suggest checking if the RadCaptcha httpHandler is registered in your Sharepoint project as shown in this help article.

Since you are using authentication, you also need to allow access to the RadCaptcha httpHandler to all users. This is shown in the following code snippet:

<location path="Telerik.Web.UI.WebResource.axd">
    <system.web>
        <authorization>
            <allow users="*"/>
        </authorization>
    </system.web>
</location>

I noticed that you have reported the same problem in this forum thread. Please use a separate thread for this purpose in the future as the information on the case will be easier to track.

All the best,
Slav
