public class SpnegoAuthenticator
extends AuthenticatorBase

A SPNEGO authenticator that uses the SPNEGO/Kerberos support built in to Java 6. Successful Kerberos authentication depends on the correct configuration of multiple components. If the configuration is invalid, the error messages are often cryptic although a Google search will usually point you in the right direction.

getAuthMethod

protected String getAuthMethod()

Description copied from class: AuthenticatorBase

Return the authentication method, which is vendor-specific and not defined by HttpServletRequest.

Specified by:

getAuthMethod in class AuthenticatorBase

Returns:

the authentication method, which is vendor-specific and not defined by HttpServletRequest.

initInternal

protected void initInternal()
                     throws LifecycleException

Description copied from class: LifecycleBase

Sub-classes implement this method to perform any instance initialisation required.

Overrides:

initInternal in class ValveBase

Throws:

LifecycleException - If the initialisation fails

doAuthenticate

protected boolean doAuthenticate(Request request,
 HttpServletResponse response)
                          throws IOException

Description copied from class: AuthenticatorBase

Provided for sub-classes to implement their specific authentication mechanism.

Specified by:

doAuthenticate in class AuthenticatorBase

Parameters:

request - The request that triggered the authentication

response - The response associated with the request

Returns:

true if the the user was authenticated, otherwise false, in which case an authentication challenge will have been written to the response

Throws:

IOException - If an I/O problem occurred during the authentication process

isPreemptiveAuthPossible

protected boolean isPreemptiveAuthPossible(Request request)

Description copied from class: AuthenticatorBase

Can the authenticator perform preemptive authentication for the given request?

Overrides:

isPreemptiveAuthPossible in class AuthenticatorBase

Parameters:

request - The request to check for credentials

Returns:
