java - Java 6 和 Java 7 中的 InitialLdapContext 失败

Question

我在 JAVA 5 中成功使用 GSSAPI。在 JAVA 6 和 7 中，InitialLdapContext 调用失败，并显示以下堆栈跟踪:

有人知道 Java 6 或 7 出了什么问题吗？

ktab文件是用jre 7的ktab工具创建的。

"c:\Program Files\Java\jre7\bin\ktab.exe"-a user@DOMAIN.DE 密码 -k my.keytab -n 0"c:\Program Files\Java\jre7\bin\ktab.exe"-a Service/host@DOMAIN.DE 密码 -k my.keytab -n 0

请记住:如果我使用 Java 5，InitialLdapContext 调用将按预期工作。

问题已解决。

我为 ldap_url 属性使用了别名 dns 名称。在 Java 1.5 中，别名 dns 名称已解析为真实 dns 名称。在 Java 1.6 和 1.7 中，不会发生解析。

更改为真实的 DNS 名称解决了问题。
