authenticate

public org.apache.hadoop.security.authentication.server.AuthenticationToken authenticate(javax.servlet.http.HttpServletRequest request,
                                                                                         javax.servlet.http.HttpServletResponse response)

Overrides:

authenticate in class org.apache.hadoop.security.authentication.server.KerberosAuthenticationHandler

Parameters:

request - the HTTP client request.

response - the HTTP client response.

Returns:

the authentication token for the authenticated request.

Throws:

IOException - thrown if an IO error occurred.

org.apache.hadoop.security.authentication.client.AuthenticationException - thrown if the authentication failed.
