我们正在尝试使用带有JAAS的独立Java客户端将WAFFLE用于SSO。我们在jaas.conf中提到了waffle.jaas.WindowsLoginModule,但它提示输入用户名,密码,我们认为这不是SSO的理想解决方案。任何人都可以建议如何避免这种情况吗?
仅供参考 - 我们没有使用任何网络/应用服务器。

我相信你需要SSO的服务器和客户端。您可以查看this example,它不使用登录模块,而是使用WAFFLE中包含的基础WindowsSecurityContext类来来回传递kerberos令牌以获取登录用户。

下面是在不使用服务器的情况下使用Waffle for独立Java Client进行单点登录的步骤。

对于客户端-服务器sso,您应遵循https://code.dblock.org/2010/04/08/pure-java-waffle.html 下面的代码描述了使用kerberos的独立Java sso。
import com.sun.jna.platform.win32.Sspi;
import waffle.windows.auth.IWindowsCredentialsHandle;
import waffle.windows.auth.IWindowsIdentity;
import waffle.windows.auth.IWindowsSecurityContext;
import waffle.windows.auth.impl.WindowsAccountImpl;
import waffle.windows.auth.impl.WindowsAuthProviderImpl;
import waffle.windows.auth.impl.WindowsCredentialsHandleImpl;
import waffle.windows.auth.impl.WindowsSecurityContextImpl;
public class KerberosSingleSignOn {
public static void main() {
try {
System.out.println(getWindowsIdentity().getFqn());
}
catch (Exception e) {
e.printStackTrace();
}
}
public static IWindowsIdentity getWindowsIdentity() throws Exception {
try {
byte[] kerberosToken = getServiceTicketSSPI();
WindowsAuthProviderImpl provider = new WindowsAuthProviderImpl();
IWindowsSecurityContext securityContext = provider
.acceptSecurityToken("client-connection", kerberosToken, "Kerberos");
return securityContext.getIdentity();
}
catch (Exception e) {
throw new Exception("Failed to process kerberos token");
}
}
public static byte[] getServiceTicketSSPI() throws Exception {
final String securityPackage = "Kerberos";
IWindowsCredentialsHandle clientCredentials = null;
WindowsSecurityContextImpl clientContext = null;
final String currentUser = WindowsAccountImpl.getCurrentUsername();
try {
clientCredentials = WindowsCredentialsHandleImpl.getCurrent(securityPackage);
clientCredentials.initialize();
// initial client security context
clientContext = new WindowsSecurityContextImpl();
clientContext.setCredentialsHandle(clientCredentials.getHandle());
/*OR
clientContext.setCredentialsHandle(clientCredentials);
*/
clientContext.setSecurityPackage(securityPackage);
final Sspi.SecBufferDesc continueToken = null;
do {
System.out.println("Using current username: " + currentUser);
clientContext.initialize(clientContext.getHandle(), continueToken, currentUser);
}
while (clientContext.isContinue());
return clientContext.getToken();
}
catch (Exception e) {
throw new Exception("Failed to process kerberos token");
}
finally {
if (clientContext != null)
clientContext.dispose();
if (clientCredentials != null)
clientCredentials.dispose();
}
}
}

而不是使用华夫饼干并使其变得复杂。您可以轻松使用System.getProperty(“user.name”)提供用户名。
