我正在尝试实施基于SPNEGO Kerberose的SSO，遵循http://spnego.sourceforge.net/pre_flight.html的说明。在tomcat中部署示例应用程序时，我收到以下错误。

以下是我的krb5.conf文件的内容

[libdefaults]
default_realm = VSSO.LOCAL
default_tkt_enctypes = aes128-cts rc4-hmac des3-cbc-sha1 des-cbc-md5 des-cbc-crc
default_tgs_enctypes = aes128-cts rc4-hmac des3-cbc-sha1 des-cbc-md5 des-cbc-crc
allowed_enctypes = aes128-cts rc4-hmac des3-cbc-sha1 des-cbc-md5 des-cbc-crc
[领域]
    VSSO.LOCAL = {
        kdc = adsrv.vsso.local
        default_domain = VSSO.LOCAL
}

以下是login.conf文件

spnego-client {
    com.sun.security.auth.module.Krb5LoginModule required;
};

spnego-server {
    需要com.sun.security.auth.module.Krb5LoginModule
    storeKey =真
    isInitiator = FALSE;
};
[domain_realm]
    .VSSO.LOCAL = VSSO.LOCAL

关于这个问题的任何想法？

答案 0 :(得分：0)

问题是由于自定义的'SunJaasKerberosTicketValidator'类，我已删除此自定义类，此问题现已解决。

但我现在面临另一个问题。

我已经将jdk1.7的无限安全策略文件复制到我的jre / lib / security文件夹中。 我正在使用OS Windows 2008 R2

关于这个问题的任何想法？

修改

我仍然遇到以下解码问题
