我已经使用Spring安全性使用SPNEGO实现了kerberos身份验证.
我的电脑上一切正常.
我已经使用了确切的keytab文件和在我的计算机上运行的krb5配置并将其放入测试环境中.
这两个环境都使用tomcat 6,我已经安装了精确的jdk版本.
但是,在测试环境中,我得到以下内容：

我已经在测试机器上根据this post测试了我的keytab文件,一切看起来都不错.
我的机器 – Windows 7专业版
测试机 – Windows Server 2008 R2
keytab在一台机器上有效而在另一台机器上无效的任何明显原因？
我的下一步将是重新生成密钥表,但这只是伏都教,我不喜欢伏都教.
谢谢,
利奥尔
编辑：
我没有直接使用KRB5ModuleLogin.我使用kerberos extension的弹簧安全.
在幕后它显然使用该模块,但我不知道如何配置它(可能通过krb5.conf文件).
这是我的相关弹簧配置：
<bean id="kerberosServiceAuthenticationProvider"
class="org.springframework.security.extensions.kerberos.KerberosServiceAuthenticationProvider">
<property name="ticketValidator">
<bean
class="org.springframework.security.extensions.kerberos.SunJaasKerberosTicketValidator">
<property name="servicePrincipal" value="${krb.service.prinicipal}" />
<!-- Setting keyTabLocation to a classpath resource will most likely not work in a Java EE application Server -->
<!-- See the Javadoc for more information on that -->
<property name="keyTabLocation" value="${krb.keytab.location}" />
<property name="debug" value="${krb.debug}" />
</bean>
</property>
<property name="userDetailsService" ref="LDAPUserDetailsService" />
</bean>
<!-- This bean definition enables a very detailed Kerberos logging -->
<bean
class="org.springframework.security.extensions.kerberos.GlobalSunJaasKerberosConfig">
<property name="debug" value="${krb.debug}" />
<property name="krbConfLocation" value="${krb.conf.location}"/>
</bean>
注入GlobalSunJaasKerberosConfig的krb5.conf如下：
[libdefaults]
default_realm = DOMAIN.COM
forwardable = true
proxiable = true
[realms]
DOMAIN.COM = {
kdc = controller1.domain.com
kdc = controller2.domain.com
kdc = controller3.domain.com
admin_server = controler.domain.com
default_domain = DOMAIN.COM
}
[domain_realm]
.domain.com = DOMAIN.COM
domain.com = DOMAIN.COM
[login]
krb4_convert = true
krb4_get_tickets = false

我已经调试到测试服务器,并与我的计算机进行了比较.
这是我的开发中的登录上下文的调试信息(可以工作)：

如您所见,它完全相同(除了keytab文件的位置,但正如我所说,keytab文件是相同的)
另一个区别是dev支持enc_type 18,而测试没有,但这似乎无关紧要,因为密钥类型是23(RC4-HMAC-NT),并且两者都支持.
那么,为了好的缘故,为什么测试机器会在用户尝试登录时拒绝keytab文件？
解决方法:
Java检查keytab文件的version-nummer(kvno)是否与kerberos数据库(LDAP服务器)中的版本号相同.如果两个数字都不同,则会出现此错误.
您可以通过使用jdk工具ktab.exe及其参数-n 0创建密钥表来绕过此检查.Java不会检查knvo = 0的密钥表.
但是最好不要使用ktab.exe,而是使用ADS-Server上的ktpass.exe生成密钥表,该密钥表直接在文件中写入正确的版本号.
