篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用苏打水进行LDAP身份验证相关的知识，希望对你有一定的参考价值。
我们需要在Sparkling-water中使用LDAP对用户进行身份验证。我们尝试使用Sparkling-water 1.6.13和h2O 3.14.0.2进行配置。以下是配置：
*ldaploginmodule {
org.eclipse.jetty.plus.jaas.spi.LdapLoginModule required
debug="true"
useLdaps="false"
contextFactory="com.sun.jndi.ldap.LdapCtxFactory"
hostname="localhost"
port="389"
bindDn="CN=admin,OU=Users,DC=company,DC=com"
bindPassword="password"
authenticationMethod="simple"
forceBindingLogin="true"
userBaseDn="dc=company,dc=com";
};*
使用的命令：spark-submit --class water.SparklingWaterDriver --master yarn-client --num-executors 2 --driver-memory 6g --executor-memory 4g --executor-cores 2 --conf'spark.dynamicAllocation。 enabled = false'--conf spark.ext.h2o.log.level = DEBUG --conf spark.ext.h2o.ldap.login = true --conf spark.ext.h2o.login.conf = / home / user / ldap.conf /home/user/sparkling-water-1.6.13/assembly/build/libs/sparkling-water-assembly_2.10-1.6.13-all.jar
但我们正面临一些问题。请在下面找到错误日志。非常感谢任何帮助。错误：

答案
很可能是您的环境特有的配置错误。向您组织的LDAP / AD专家寻求帮助。对外帮助的人来说并不容易。
以下是我建议用于调试LDAP问题的一些技巧。
首先，不要直接在Sparkling Water中调试它。在纯粹的独立H2O中调试它，没有Hadoop或Spark，因此您可以隔离问题并且很容易看到发生了什么，并且您不必寻找stdout / stderr / logs。
其次，您可以通过将以下文件添加到类路径来启用DEBUG jetty日志级别并获取有关ldaploginmodule正在执行的操作的更多信息：
jetty-logging.properties
org.eclipse.jetty.util.log.class=org.eclipse.jetty.util.log.StdErrLog
org.eclipse.jetty.LEVEL=DEBUG
所以像这样运行（确保jetty-logging.properties在当前目录中）：
java -cp h2o.jar:. water.H2OApp -ldap_login -login_conf ldap-config-file
另一答案
另外两个说明：
- 不要使用Sparkling Water 1.6并升级
- 升级后，对于LDAP conf，您需要修改LoginModlue对
ai.h2o.org.eclipse.jetty.plus.jaas.spi.LdapLoginModule required的引用
