  Deprecated.

### NegotiateScheme

    public NegotiateScheme()

  Deprecated.

Method Detail

### getSchemeName

    public String getSchemeName()

  Deprecated.
  Returns textual designation of the Negotiate authentication scheme.

  Returns:
    `Negotiate`

### authenticate

    public Header authenticate(Credentials credentials,
                               HttpRequest request)

  Description copied from interface: `AuthScheme`
  Produces an authorization string for the given set of `Credentials`.

  Specified by:
    `authenticate` in interface `AuthScheme`
  Overrides:
    `authenticate` in class `GGSSchemeBase`
  Parameters:
    `credentials` - The set of credentials to be used for athentication
    `request` - The request being authenticated
  Returns:
    the authorization string
  Throws:
    `AuthenticationException` - if authorization string cannot be generated due to an authentication failure

### authenticate

    public Header authenticate(Credentials credentials,
                               HttpRequest request,
                               HttpContext context)
                        throws AuthenticationException

  Deprecated.
  Produces Negotiate authorization Header based on token created by processChallenge.

  Specified by:
    `authenticate` in interface `ContextAwareAuthScheme`
  Overrides:
    `authenticate` in class `GGSSchemeBase`
  Parameters:
    `credentials` - Never used be the Negotiate scheme but must be provided to satisfy common-httpclient API. Credentials from JAAS will be used instead.
    `request` - The request being authenticated
    `context` - HTTP context
  Returns:
    an Negotiate authorisation Header
  Throws:
    `AuthenticationException` - if authorisation string cannot be generated due to an authentication failure

### generateToken

    protected byte[] generateToken(byte[] input,
                                   String authServer)
                            throws GSSException

  Deprecated.
  Specified by:
    `generateToken` in class `GGSSchemeBase`
  Throws:
    `GSSException`

### getParameter

    public String getParameter(String name)
