Hi - 

I have an MVC.NET web API project that I need to get SSO to work. Since this is a Web API project, I'm planning to use DatabaseSSOSessionStore to store the session ID.
I created the session table in the DB as per your documentation but nothing seems to be writing to the table.
Here's my code:

   string connString = System.Configuration.ConfigurationManager.ConnectionStrings["DefaultConnection"].ToString();
    SAMLController.SSOSessionStore = new DatabaseSSOSessionStore("System.Data.SqlClient", connString, "SAML_SSO_Sessions");
   
    string partnerSP = System.Configuration.ConfigurationManager.AppSettings["ws_DotLoop_SAML"];
    string targetUrl = "";
    string userName = "";
    HttpResponse response = null;

    userName = User.Identity.Name;
    AssociateObject loggedInUser = GetAssociate(userName);

    IDictionary<string, string> attributes = new Dictionary<string, string>();
    attributes.Add("email", loggedInUser.email);

    SAMLIdentityProvider.InitiateSSO(
      response,
      userName,
      attributes,
      targetUrl,
      partnerSP);



Here's the output from the logs (masked sensitive areas):

iisexpress.exe Information: 0 : DotNetOpenAuth.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=2780ccd10d57b246 (official)

Since this is a web api project, I don't have ASP.NET session cookies enabled. But according to the logs it's still trying to use session cookies even though I am specifying SSOSessionStore = DatabaseSSOSessionStore.

I am quite new to this so any help would be greatly appreciated. Thanks!

In the product version you have we still use the ASP.NET session ID as the key into the SSO session store.
In later releases we use a separate cookie to provide the key so you don't have to enable ASP.NET sessions.
You could enable ASP.NET session cookies enabled.
The SAML SSO session data will be stored in the database and the ASP.NET session cookie will be used to provide the session ID which is used as the primary key into the database table.
Alternatively, please contact us to discuss upgrading to the latest release.

Thanks. What do I need to do to get the latest release? We are already using this on another regular site with sessions enabled and wanted to make sure it would not break anything there if we upgrade. Do I just replace the dll in my project?

You would need to rebuild with the new DLL.
There shouldn't be any issues in upgrading.

   Hi - I got the latest dll but still don't see any entries in the SQL database. Part of the code below:

string connString = ConfigurationManager.ConnectionStrings["DefaultConnection"].ToString();
    SAMLController.SSOSessionStore = new DatabaseSSOSessionStore("System.Data.SqlClient", connString, "SAML_SSO_Sessions")
    {
      SessionIDDelegate = delegate()
      {
       return null;
      }
    };

The error indicates that the SessionIDDelegate used by the DatabaseSSOSessionStore is returning null for the SSO session ID.
This session ID is used to uniquely identify each user's session.
By default the SessionIDDelegates.GetSessionIDFromSAMLCookie returns the session ID from a SAML session cookie.
There's also a SessionIDDelegates.GetSessionIDFromHttpSessionState which returns the session ID from the ASP.NET session.
And of course you can write your own custom delegate.
In your code above the SessionIDDelegate is returning null.
You need to either use of of our delegates or provide a complete implementation of your custom delegate.
I recommend using the default delegate.

Thanks for getting back. Could you provide some c# sample code to implement this? Like I mentioned earlier, I am not using ASP.NET session cookies. I was told that the newer version used a separate cookie to track the session ID. How do I do this?
Thanks.

That's correct. Bu default, it uses a separate cookie.
Don't specify a delegate and the separate cookie will be used.
SAMLController.SSOSessionStore = new DatabaseSSOSessionStore("System.Data.SqlClient", connString, "SAML_SSO_Sessions");

SAMLController.SSOSessionStore = new DatabaseSSOSessionStore("System.Data.SqlClient", connString, "SAML_SSO_Sessions");

I made the change and get this error in my code:

System.NullReferenceException: Object reference not set to an instance of an object.
at ComponentSpace.SAML2.Bindings.HTTPPostBinding.SendResponse(HttpResponse httpResponse, String targetURL, XmlElement samlMessage, String relayState)

at ComponentSpace.SAML2.SAMLIdentityProvider.InitiateSSO(HttpResponse httpResponse, String userName, IDictionary`2 attributes, String relayState, String partnerSP)

However I still don't see any entries in the database and no noticeable SQL errors in the logs. Are the session ID's automatically deleted from the database?

If the database is being updated you should see INSERT/UPDATE/DELETE entries in the SAML log file as well. All I see are SELECTs.
Was the NullReferenceException part of this log?
The log looks incomplete so perhaps the exception occurred without SAML SSO completing correctly and therefore the database wasn't updated.
Please send the complete SAML log file as an email attachment to support@componentspace.com mentioning your forum post and I'll take a closer look.
