Solaris 10 实现安全Kerberos 身份验证

dn001 2009-06-19 00:12:17

　　在 keytab 文件中创建服务主体条目的方法有很多种。清单 4 显示了其中一种方法，创建 Kerberos 服务主体，并使用承载 KDC 的 AIX 计算机中的 IBM NAS 提供的 kadmin 工具将其条目添加到 keytab 文件中。然后使用 FTP 将 keytab 文件从 AIX 计算机传输到合适的 Solaris 计算机。Kerberos 实用工具，如 ktutil，在需要的情况下也可以用来完成相同的任务。

　　清单 4. 创建 krb5.keytab 文件
