Method Detail

init

public abstract void init(java.util.Properties config)
                   throws javax.servlet.ServletException

This function is invoked when the filter is coming up. we try to get the mapr serverkey which will be used later to decrypt information sent by the client

Also since we may be required to authenticate using Kerberos we invoke the kerberos init code after checking if the principal and keytab specified in the config file exist. If they don't exist we don't invoke the kerberos init code because we don't expect to use kerberos.

Specified by:

init in interface AuthenticationHandler

Overrides:

init in class MultiMechsAuthenticationHandler

Parameters:

config - configuration properties to initialize the handler.

Throws:

javax.servlet.ServletException

maprAuthenticate

public abstract AuthenticationToken maprAuthenticate(javax.servlet.http.HttpServletRequest request,
                                                     javax.servlet.http.HttpServletResponse response)
                                              throws java.io.IOException,
                                                     AuthenticationException

Throws:

java.io.IOException

destroy

public void destroy()

Description copied from interface: AuthenticationHandler
