Web.config custom section not being recognized - web-config

Question

I am trying to develop an application that uses the package SAML2.dll (which I downloaded with NuGet). To properly configure my application, we must add a few sections in the Web.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
**<section name="saml2" type="SAML2.Config.Saml2Section, SAML2" />**
</configSections>
<connectionStrings>...</connectionStrings>
<appSettings>...</appSettings>
<system.web>...</system.web>
<system.webServer>
<modules>
<remove name="FormsAuthentication" />
</modules>
**<handlers>
<remove name="SAML2.Protocol.Saml20SignonHandler" />
<remove name="SAML2.Protocol.Saml20LogoutHandler" />
<remove name="SAML2.Protocol.Saml20MetadataHandler" />
<add name="SAML2.Protocol.Saml20SignonHandler" verb="*" path="Login.ashx" type="SAML2.Protocol.Saml20SignonHandler, SAML2" />
<add name="SAML2.Protocol.Saml20LogoutHandler" verb="*" path="Logout.ashx" type="SAML2.Protocol.Saml20LogoutHandler, SAML2" />
<add name="SAML2.Protocol.Saml20MetadataHandler" verb="*" path="Metadata.ashx" type="SAML2.Protocol.Saml20MetadataHandler, SAML2" />
</handlers>**
</system.webServer>
<runtime>...</runtime>
<entityFramework>...</entityFramework>
**<saml2>
<serviceProvider id="urn:issuer" server="http://localhost:3301/">
<endpoints>
<endpoint localpath="Login.ashx" type="signon" redirectUrl="~/AuthenticatedHomePage" />
<endpoint localpath="Logout.ashx" type="logout" redirectUrl="~/HomePage" />
<endpoint localpath="Metadata.ashx" type="metadata" />
</endpoints>
<nameIdFormats allowCreate="true">
<add format="urn:oasis:names:tc:SAML:2.0:nameid-format:transient" />
</nameIdFormats>
<authenticationContexts comparison="Exact">
<add context="urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport" referenceType="AuthnContextClassRef" />
</authenticationContexts>
</serviceProvider>
<identityProviders metadata="C:\Users\myUser\Desktop\testMetadata\metadata_Kit_net.xml" />
<metadata>
<contacts>
<contact type="Administrative" company="" givenName="" surName="" email="" phone="" />
</contacts>
<requestedAttributes>
<add name="urn:cn" />
</requestedAttributes>
</metadata>
</saml2>**
</configuration>
The issue is that the session tag has no recognized tags, I'm having 39 messages like (one for each element inside the tag):
impossible to find schema information for the element 'saml2'.
impossible to find schema information for the element 'serviceProvider'.
impossible to find schema information for the element 'id'.
...
I looked into my dll's source code (SAML2.dll) and it seams to have all the tags definitions (as written in the first Web.config part: ):
using System.Configuration;
namespace SAML2.Config
{
/// <summary>
/// SAML2 Configuration Section.
/// </summary>
public class Saml2Section : ConfigurationSection
{
/// <summary>
/// Gets the section name.
/// </summary>
public static string Name { get { return "saml2"; } }
#region Elements
/// <summary>
/// Gets or sets the actions to perform on successful processing.
/// </summary>
/// <value>The actions.</value>
[ConfigurationProperty("actions")]
public ActionCollection Actions
{
get { return (ActionCollection)base["actions"]; }
set { base["actions"] = value; }
}
/// <summary>
/// Gets or sets the identity providers.
/// </summary>
/// <value>The identity providers.</value>
[ConfigurationProperty("identityProviders")]
public IdentityProviderCollection IdentityProviders
{
get { return (IdentityProviderCollection)base["identityProviders"]; }
set { base["identityProviders"] = value; }
}
/// <summary>
/// Gets or sets the metadata.
/// </summary>
/// <value>The metadata.</value>
[ConfigurationProperty("metadata")]
public MetadataElement Metadata
{
get { return (MetadataElement)base["metadata"]; }
set { base["metadata"] = value; }
}
/// <summary>
/// Gets or sets the service provider.
/// </summary>
/// <value>The service provider.</value>
[ConfigurationProperty("serviceProvider")]
public ServiceProviderElement ServiceProvider
{
get { return (ServiceProviderElement)base["serviceProvider"]; }
set { base["serviceProvider"] = value; }
}
...
When I call the URL http://localhost:3301/Login.ashx, I'm having the error:
{"Attribute 'localpath' not recognized. (c:\users\myUser\documents\visual studio 2013\Projects\saml20app\saml20app\web.config line 98)"}, and it points exactly to the line
<endpoint localpath="Login.ashx" type="signon" redirectUrl="~/AuthenticatedHomePage" />
Can someone please help me with this error?
Thanks in advance for your help,
Marc

Answer 1

Got tried of trying to get this to work so I opened the assembly with ILSpy to see what it wanted:
<endpoint localPath="Login.ashx" type="SignOn" redirectUrl="~/AuthenticatedHomePage" />
<endpoint localPath="Logout.ashx" type="Logout" redirectUrl="~/HomePage" />
<endpoint localPath="Metadata.ashx" type="Metadata" />
The type attribute in the example web.config makes it unhappy too. Thankfully it lets you know the enumerated values it expects.
Hope this help.
