In my ASP.NET(4.5) Forms application I'm trying to enable authentication and authorization and not able to get it to work. I found instructions to add the below to the Web.config file, but the all request to any pages get the error HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.

Also, in my Web.config file there is an error message "The element 'system.web' has invalid child element 'forms'.

Given Visual Studio creates the authentication codes out of the box, I thought this would be something that should be easy to enable. How can I fix this?

I found this info online to add to my Web.config to enable authentication and authorization:

<system.web>
  <authentication mode="Forms">
    <forms loginUrl="~/Account/Login" timeout="30" />
  </authentication>
</system.web>

<system.webServer>
  <security>
    <authentication>
      <anonymousAuthentication enabled="true" />
    </authentication>
  </security>
<system.webServer>

Here is my Web.config without the connection strings elements:

<?xml version="1.0" encoding="utf-8"?>

are you placing only 1 config file in your root folder? look here stackoverflow.com/questions/1866229/…MethodMan
Why doesn't your loginUrl have an extension? Shouldn't it read like this: <forms loginUrl="~/Account/Login.aspx" timeout="30" />?Ian

The web.config is wrong. You have this:

<authentication mode="Forms" />
<forms loginUrl="~/Account/Login" timeout="30" />

And it should be:

<authentication mode="Forms" >
   <forms loginUrl="~/Account/Login" timeout="30" />
</authentication>
