Package com.kerb4j.client

Class SpnegoClient

java.lang.Object

com.kerb4j.client.SpnegoClient

public final class SpnegoClient
extends Object

This Class may be used by custom clients as a convenience when connecting to a protected HTTP server.

A krb5.conf is required when using this class. Take a look at the spnego.sourceforge.net documentation for an example krb5.conf file. Also, you must provide a keytab file, or a username and password, or allowtgtsessionkey.

To see a working example and instructions on how to use a keytab, take a look at the creating a client keytab example.

loginWithKeyTab

public static SpnegoClient loginWithKeyTab(String principal,
 String keyTabLocation)

Creates an instance where authentication is done using keytab file

Parameters:
