FBA Authentication and Security Token Error

Question

There is a login form with any authentication logic. I enter login and password, then I click "Login" and get error "The method or operation is not implemented" in this code line:

SecurityToken tk = SPSecurityContext.SecurityTokenForFormsAuthentication
  (
     new Uri(SPContext.Current.Web.Url),
     "MyUserProvider",
     "MyRoleProvider",
     this.txLogin.Text,
     this.txPassword.Text
  );

================================================

Server Error in '/' Application.

The method or operation is not implemented.

But I have assembly with custom Membership and Roles Provider and all methods are implemented! Where is a mistake?

You may be calling base membership functions directly from your custom membership and roles provider, like:

Membership.FindUsersByEmail("myemail@here.com");

These will get handled by the default membership provider, which won't be your membership provider, but will be the SPClaimsAuthMembershipProvider. SPClaimsAuthMembershipProvider doesn't implement a lot of the base methods - they will return a not implemented exception.

If you want to get the web app's selected membership provider to reference, you can use the following code:

public static string GetMembershipProvider(SPSite site)
{
    // get membership provider of whichever zone in the web app is fba enabled 
    SPIisSettings settings = GetFBAIisSettings(site);
    return settings.FormsClaimsAuthenticationProvider.MembershipProvider;
}

public static SPIisSettings GetFBAIisSettings(SPSite site)
{
    SPIisSettings settings = null;

    // try and get FBA IIS settings from current site zone
    try
    {
        settings = site.WebApplication.IisSettings[site.Zone];
        if (settings.AuthenticationMode == AuthenticationMode.Forms)
            return settings;
    }
    catch 
    { 
        // expecting errors here so do nothing                 
    }

    // check each zone type for an FBA enabled IIS site
    foreach (SPUrlZone zone in Enum.GetValues(typeof(SPUrlZone)))
    {
        try
        {
            settings = site.WebApplication.IisSettings[(SPUrlZone)zone];
            if (settings.AuthenticationMode == AuthenticationMode.Forms)
                return settings;
        }
        catch
        { 
            // expecting errors here so do nothing                 
        }
    }

    // return null if FBA not enabled
    return null;
}

Some things to try:

Did you register the providers in the web application through the Cental Admin?
Did you register the providers in your web.config?
What happens if you use SPClaimsUtility.AuthenticateFormsUser instead?
