how to integrate #ldap with #emr

 To integrate LDAP with Amazon EMR (Elastic MapReduce), follow these steps:

1.       Create an LDAP directory service in AWS. You can use Amazon Managed AD or Simple AD to create a directory service.

2.       Create an IAM role for EMR to access the LDAP directory. You will need to create a policy that grants the EMR service access to the LDAP directory. Here's an example policy that you can use:

{

                "Version": "2012-10-17",

                "Statement": [{

                                "Effect": "Allow",

                                "Action": [

                                                "ds:DescribeDirectories",

                                                "ds:CreateComputer",

                                                "ds:DeleteComputer",

                                                "ds:DescribeComputers",

                                                "ds:JoinDirectory"

                                ],

                                "Resource": "*"

                }]

}

 

3.       Launch an EMR cluster and configure it to use the IAM role that you created in step 2.

4.       Configure the EMR cluster to join the LDAP directory. You can do this by adding the following configuration to the EMR cluster:

[{

                "Classification": "directory-service",

                "Properties": {

                                "directory_service_name": "<directory_service_name>",

                                "directory_service_password": "<directory_service_password>",

                                "directory_service_username": "<directory_service_username>",

                                "directory_service_domain_name": "<directory_service_domain_name>",

                                "directory_service_dns_ips": "<directory_service_dns_ips>"

                },

                "Configurations": []

}]

 

Replace the following variables with your own values:

 

<directory_service_name>: the name of the LDAP directory service that you created in step 1.

<directory_service_password>: the password for the user that you want to use to join the EMR cluster to the LDAP directory.

<directory_service_username>: the username for the user that you want to use to join the EMR cluster to the LDAP directory.

<directory_service_domain_name>: the domain name of the LDAP directory.

<directory_service_dns_ips>: the IP addresses of the DNS servers for the LDAP directory.

 

Start the EMR cluster.

 

Once the EMR cluster is running, you should be able to authenticate users against the LDAP directory. You can test this by SSHing into the EMR cluster and running an LDAP search using the ldapsearch command.
