AWS SAML AUTH with CLI/Programatic access the easiest way

Hello Guys,

As you know from my previous blog that I have setup keycloak server with Azure AD as identity federation now most of you have face the problem about getting the access and secret access key for those role. I have also face the same problem and yet there is no easy solution for this so after much searching on internet i got a radical idea why not use a google chrome plugin, Its not the case i have tried the other solution like saml2aws and other but they want help you if you are login in keycloak using federated identity.so the below method will work with other sso provider as well.
 
1. Search for SAML to AWS key converter & add the plugin to Chrome

 

2. After adding the extension to the chrome, it will appear as below

We are now ready login AWS through KeyCloak and generate AWS Access Keys.

Login AWS through KeyCloak

1. Click on the below link to login to KeyCloak.
https://keycloakserver/auth/realms//account/applications

2. Login through your sso provider or keycloak


3. After Logging keycloak, navigate to the Application & choose the account to login (eg.AWS application name)

4. After selecting the required application you will be navigated to the AWS account and credentials will be generated for the same. and downloaded in your browser its the most easy way a user can login and have his programmatic access with him.

Free SSO with AWS SAML on Prem

Hello Guys,

I started working with a start up and they have about 7 to 8 AWS account and user management in all the AWS account is becoming a problem as well as the users who are leaving the company or in the company also using there programmatic access here and there,
     If we delete or inactive the users then some application is going to stop working so my manager want to came up with plan we have gone through many options and we also have budget issue as its a start up company.so we came up with a plan of using keycloak as our SSO SAML provider backed with postgress and i also want to demonstrate the capability of kubernetes so i deployed it in the kubernetes cluster
   I have use help to install keycloak on the kubernetes cluster which a got from codecentric repo.
https://codecentric.github.io/helm-charts i am also using kubeapps to deploy it in my kubernetes environement.

once install i have started configuring the keycloak

1) First step you need to do is — get saml-metadata.xml from Amazon AWS.

2) After you saved saml-metadata.xml file, go to your Keycloak server, go to “Clients” section and create new client:

your_realm_name — is the name of the keycloak realm, for which you configure SAML client

The only fields you need to fill are:

“Base URL” and “IDP Initiated SSO URL Name”

Set your “Base URL” to:  /auth/realms/<your_realm_name>/protocol/saml/clients/amazon-aws

and “IDP Initiated SSO URL Name” to  amazon-aws

5) Press “Save”

After you saved client settings, go to “Installation” tab, select “Mode Auth Mellon files” and press “Download”  zip file will get downloaded you need to extract the same  and file name idp-metadata.xml

Amazon AWS Service Provider setup

1) After you downloaded idp-metadata.xml file, go to your Amazon AWS account

2) Go to “IAM” section, select “Identity providers” and press “Create Provider” button.

3) Choose “SAML” as the provider type, set provider name and upload idp-metadata.xml file downloaded  and extracted from Keycloak server.

4) Press “Next Step” and then “Create”.

5) After you created your SAML Identity Provider, you need to create IAM role for this provider.

6) Go to “IAM” section, select “Roles”.

7) Press “Create New Role”, set role name.

For “Select Role Type” choose

“SAML 2.0 fedration”

and select your Saml provider which we have created earlier

PART 2: Keycloak Identity Provider setup

1) After IAM SAML role in AWS has been created, go to role summary and copy Role ARN, it should look like this:

arn:aws:iam::aws_acct_id:role/aws_iam_saml_role,arn:aws:iam:aws_acct_id:saml-provider/aws_iam_saml_idp

Go back to your Keycloak server, go to your realm in which you created AWS SAML client, go to “Roles” tab and press “Add Role”:

aws_acct_id — your AWS account ID, aws_iam_saml_role — AWS IAM SAML role, aws_iam_saml_idp — AWS IAM SAML Identity Provider

2) After that, go to “Mappers” section and create mappers for “Session Role”, “Session Duration” and “Session Name”

“Session Role” mapper:

“Session Name” mapper:

“Session Duration” mapper:

These mappers are required as per Amazon AWS SAML documentation.

3) After “Mappers”, go to Keycloak realm “Manage” section, select “Users” or “Groups” and choose, which group or user will be assigned to AWS SAML role, and assign it:

aws_acct_id — your AWS account ID, aws_iam_saml_role — AWS IAM SAML role, aws_iam_saml_idp — AWS IAM SAML Identity Provider

5) And, finally, go back to your defined AWS client, and press “Base URL” link:

your_realm_name — is the name of the keycloak realm, for which you configure SAML client

6) After you press “Base URL” link, it should redirect you to Keycloak login page, where you’ll need to enter user name and password for the user, who is member of a group, which has been assigned to AWS IAM SAML role, defined in Keycloak.

And after you enter your credentials, hopefully, you’ll be redirected to Amazon AWS console.

You can integrate the Keycloak with  Azure AD well.

Click on identity provider select microsoft  and fill the retails as requested Application ID and Application secret and you will be able to authenticate in keycloak using azure AD.

For the CLI/Programatic  access i will get bacl to you in my next blog
