Jenkins尝试实现AD登录后运行失败

Question

我有一个尝试使用 Active Directory 设置的 jenkins 实例。此后，没有任何用户可以使用任何凭据登录，因此我进入服务器并删除了 Active Directory 插件，试图删除配置并重新启动服务器。我现在看到以下错误

有没有其他方法可以禁用该插件的所有出现，以便我们可以登录？

这可能是因为您的/var/lib/jenkins/config.xml其中有一个如下所示的部分：

  <securityRealm class="hudson.plugins.active_directory.ActiveDirectorySecurityRealm" plugin="active-directory@2.6">
    <domains>
      <hudson.plugins.active__directory.ActiveDirectoryDomain>
        <name>ad.example.com</name>
        <bindPassword>{some obfuscated password here}</bindPassword>
      </hudson.plugins.active__directory.ActiveDirectoryDomain>
    </domains>
    <startTls>true</startTls>
    <groupLookupStrategy>RECURSIVE</groupLookupStrategy>
    <removeIrrelevantGroups>true</removeIrrelevantGroups>
    <tlsConfiguration>TRUST_ALL_CERTIFICATES</tlsConfiguration>
  </securityRealm>

您可以通过以下步骤获得管理员访问权限。请注意，这将（暂时）向匿名用户授予管理员访问权限，因此请谨慎使用！

关闭 Jenkins，securityRealm从您的 中删除上述部分config.xml，并更改以下部分：

<useSecurity>true</useSecurity>

对此：

<useSecurity>false</useSecurity>

再次启动詹金斯。此时，您可以使用 Web UI 重新安装/配置 authn/authz 插件。
