How do I get the SecurityToken from the ClaimsPrincipal?

How to get SecurityToken

from ClaimsPrincipal

?

I need this because I want to pass it from MVC application to WCF service in AuthenticationManager / Authenticate .

In the Authenticate method, BootstrapContext is null. And even after authenticating, it sometimes gets null, making it not a reliable choice for me.

This is my Authentication Manager class:

public override ClaimsPrincipal Authenticate (string resourceName, ClaimsPrincipal incomingPrincipal) {string passportID = incomingPrincipal.Identity.GetPassportID (). ToString ();

try
{
    // I need the token here 
    SecurityToken token = GetToken(incomingPrincipal);
    return base.Authenticate(resourceName, incomingPrincipal);
}
catch (Exception ex)
{
    throw new SecurityException("User is not authenticated.", ex);
}

}

I ended up using this code:

BootstrapContext context = ClaimsPrincipal.Current.Identities.First().BootstrapContext as BootstrapContext;
SecurityToken token = context.SecurityToken;

if (context.SecurityToken != null)
{
    token = context.SecurityToken;
}
else if (String.IsNullOrWhiteSpace(context.Token) == false)
{
    var handlers = FederatedAuthentication.FederationConfiguration.IdentityConfiguration.SecurityTokenHandlers;
    token = handlers.ReadToken(new XmlTextReader(new StringReader(context.Token)));
}

var actAsToken = GetActAsToken(token);


You can learn more about this in this . It looks like it context.SecurityToken

will be cleaned up for some time so it cannot be too dependent on it.

<identityConfiguration saveBootstrapContext="true">


This will store the bootstrap token in the ClaimsPrincipal.BootstrapContext.
