介绍
hadoop生态里面常用的安全认证无非两种kerberos和ldap，kerberos的繁琐已经领教过了，ldap还好在生产中也用过，看来hive+ldap+sentry用起来应该比较顺手一些。hive+sentry的配置见Sentry Service for Hive Without kerberos。ldap的部署见openldap+phpldapadmin

</configuration>ps：注意openladp的配置
PHPladpadmin
$servers = new Datastore();
$servers->newServer('ldap_pla');
$servers->setValue('server','name','Bigdata LDAP Server');
$servers->setValue('server','host','10.205.54.14');
$servers->setValue('server','port',389);
$servers->setValue('server','base',array('dc=bdbigdata,dc=com'));
$servers->setValue('login','auth_type','session');
$servers->setValue('login','bind_id','cn=Manager,dc=bdbigdata,dc=com');
$servers->setValue('login','bind_pass','bigdata');
$servers->setValue('server','tls',false);
设置LDAP
通过phpldapadmin添加修改用户更方便一些
Hive验证
通过hive用户登录，输入错误密码
通过hive登录，输入正确密码(密码为在phpladpadmin中设置的密码)
