我正在使用kerberos协议来验证Java Swing应用程序的用户。我能够在客户端成功进行身份验证，但在服务器端获取用户凭据和角色时遇到问题，我有ejbs需要某些角色才能创建这些ejbs。
jboss-app.xml看起来像
<jboss-app>
<security-domain>java:/jaas/spnego-server</security-domain>
<loader-repository>paymenttracker:loader=paymenttracker.ear</loader-repository>
</jboss-app>
调用Subject.doAs（s，lv）的客户端类; lv是一个扩展PrivilegedExceptionAction的类。
在服务器端，jboss服务器中的login-config.xml获得了以下设置
<application-policy name="spnego-server"><authentication>
<login-module code="com.sun.security.auth.module.Krb5LoginModule" flag="required" >
<module-option name="storeKey">true</module-option>
<module-option name="debug">true</module-option>
<module-option name="useKeyTab">true</module-option>
<module-option name="keyTab">file://c:/ker/tem.keytab</module-option>
<module-option name="principal">HTTP/ws6421.ebrd.com</module-option>
<module-option name="doNotPrompt">true</module-option>
<module-option name="isInitiator">false</module-option>
</login-module></authentication>
</application-policy>
收到以下错误：
