Rundeck ldap 连接以 NullPointerException 结束

Question

我目前正在将 rundeck v2.11.3迁移到v3.4.0 （在v3.4.0容器中），我的方法是设置全新安装并稍后移动所有内容。 目前，我无法设置 LDAP 连接（由运行在 MS Windows Server 2016 上的 Active Directory 提供）。 我在这里使用来自 DockerHub 的容器rundeck/rundeck:3.4.0 ，我的jaas-loginmodule.conf如下所示：

rundeck {
    com.dtolabs.rundeck.jetty.jaas.JettyCombinedLdapLoginModule sufficient
        debug="true"
        contextFactory="com.sun.jndi.ldap.LdapCtxFactory"
        providerUrl="ldap://10.16.0.4:389"
        bindDn="CN=devldap,CN=Users,DC=mycompany,DC=de"
bindPassword="xxx"
        authenticationMethod="simple"
        forceBindingLogin="true"
        forceBindingLoginUseRootContextForRoles="true"
        userBaseDn="dc=mycompany,dc=de"
        userRdnAttribute="userPrincipalName"
        userIdAttribute="userPrincipalName"
        userPasswordAttribute="unicodePwd"
        userObjectClass="user"
        roleBaseDn="ou=dev,ou=adgroups,dc=mycompany,dc=de"
        roleNameAttribute="cn"
        roleMemberAttribute="member"
        roleObjectClass="group"
        rolePrefix=""
        cacheDurationMillis="600000"
        reportStatistics="true"

    ;

    org.eclipse.jetty.jaas.spi.PropertyFileLoginModule required
        debug="true"
        file="/home/rundeck/server/config/realm.properties";


};

尝试使用 ldap 用户登录时，出现以下错误堆栈：

我想知道，是否有任何方法可以实际调试连接并查看它是否是某些配置错误（上面的配置取自 rundeck 的现有实例，它工作正常）或者是否可能是 rundeck 应用程序中的某些错误。

Answer 1

我看到示例AD 配置的一些差异（AD 配置的第一行调用另一个模块，还检查userRdnAttributte和userIdAttribute值，最后，确保使用 OpenJDK 11 启动 Rundeck）。

无论如何，我使用以下多重身份验证配置成功测试：

multiauth {
  com.dtolabs.rundeck.jetty.jaas.JettyCachingLdapLoginModule sufficient
      debug="true"
      contextFactory="com.sun.jndi.ldap.LdapCtxFactory"
      providerUrl="ldap://xxx.xxx.xxx.xxx:389"
      bindDn="admin@example.local"
      bindPassword="password"
      authenticationMethod="simple"
      forceBindingLogin="true"
      userBaseDn="OU=Users,OU=company,DC=example,DC=local"
      userRdnAttribute="sAMAccountName"
      userIdAttribute="sAMAccountName"
      userPasswordAttribute="unicodePwd"
      userObjectClass="user"
      roleBaseDn="OU=Roles,OU=company,DC=example,DC=local"
      roleNameAttribute="cn"
      roleMemberAttribute="member"
      roleObjectClass="group"
      cacheDurationMillis="300000"
      //supplementalRoles="admin"
      reportStatistics="true";
 
  org.eclipse.jetty.jaas.spi.PropertyFileLoginModule required
    debug="true"
    file="/home/user/rundeck/server/config/realm.properties";
};

并以这种方式启动 rundeck：

#!/bin/bash
 
# rundeck information
version=rundeck-3.4.1-20210715.war
min=1024m
max=2048m
 
# run
java -Xms$min -Xmx$max -Drundeck.jaaslogin=true -Dloginmodule.conf.name=jaas-multiauth.conf -Dloginmodule.name=multiauth -jar $version
