Creates a security token authenticator based on the SecurityTokenRequirement.

public:
 override System::IdentityModel::Selectors::SecurityTokenAuthenticator ^ CreateSecurityTokenAuthenticator(System::IdentityModel::Selectors::SecurityTokenRequirement ^ tokenRequirement, [Runtime::InteropServices::Out] System::IdentityModel::Selectors::SecurityTokenResolver ^ % outOfBandTokenResolver);

public override System.IdentityModel.Selectors.SecurityTokenAuthenticator CreateSecurityTokenAuthenticator (System.IdentityModel.Selectors.SecurityTokenRequirement tokenRequirement, out System.IdentityModel.Selectors.SecurityTokenResolver outOfBandTokenResolver);

override this.CreateSecurityTokenAuthenticator : System.IdentityModel.Selectors.SecurityTokenRequirement * SecurityTokenResolver -> System.IdentityModel.Selectors.SecurityTokenAuthenticator

Public Overrides Function CreateSecurityTokenAuthenticator (tokenRequirement As SecurityTokenRequirement, ByRef outOfBandTokenResolver As SecurityTokenResolver) As SecurityTokenAuthenticator

Parameters

tokenRequirement: SecurityTokenRequirement

The security token requirement.

outOfBandTokenResolver: SecurityTokenResolver

When this method returns, contains a SecurityTokenResolver. This parameter is passed uninitialized.

Returns

SecurityTokenAuthenticator

The security token authenticator.

Exceptions

ArgumentNullException

tokenRequirement is null.

NotSupportedException

A security token authenticator cannot be created for the tokenRequirement that was passed in.

Examples

The following code is an example of how to override this method.

internal class MyServiceCredentialsSecurityTokenManager :
    ServiceCredentialsSecurityTokenManager
{
    ServiceCredentials credentials;
    public MyServiceCredentialsSecurityTokenManager(ServiceCredentials credentials)
        : base(credentials)
    {
        this.credentials = credentials;
    }

    public override SecurityTokenAuthenticator CreateSecurityTokenAuthenticator
        (SecurityTokenRequirement tokenRequirement, out SecurityTokenResolver outOfBandTokenResolver)
    {
        // Return your implementation of the SecurityTokenProvider based on the
        // tokenRequirement argument.
        SecurityTokenAuthenticator result;
        if (tokenRequirement.TokenType == SecurityTokenTypes.UserName)
        {
            MessageDirection direction = tokenRequirement.GetProperty<MessageDirection>
                (ServiceModelSecurityTokenRequirement.MessageDirectionProperty);
            if (direction == MessageDirection.Input)
            {
                outOfBandTokenResolver = null;
                result = new MySecurityTokenAuthenticator();
            }
            else
            {
                result = base.CreateSecurityTokenAuthenticator(tokenRequirement, out outOfBandTokenResolver);
            }
        }
        else
        {
            result = base.CreateSecurityTokenAuthenticator(tokenRequirement, out outOfBandTokenResolver);
        }

Remarks

An outOfBand token resolver can optionally be returned by the method, which is used by the WCF security processor to resolve tokens that are not in the SOAP message when processing security. The SecurityTokenAuthenticator that is returned by this method validates tokens and extracts claims. One SecurityTokenAuthenticator is created for each class derived from ServiceModelSecurityTokenRequirement.
