How to Configure SAML Authentication

Overview

This guide outlines configuring single sign-on (SSO) authentication using a Security Assertion Markup Language (SAML) for a customer-managed installation.

Note: For assistance with configuring SSO authentication in the kinops hosted platform, contact Kinetic Support.

Prerequisites

Before starting the configuration process, open your desired terminal emulator, access the command line interface (CLI), and run the command below that corresponds to your package manager. This is required to parse the JSON used during the installation process.

sudo yum install jq

sudo apt-get update
sudo apt-get install jq

sudo dnf install jq

Additionally, ensure you can access a code editor to create script files. The instructions in this document use the vim editor, but you can use any editor you like.

Workstation Setup

From the workstation communicating with the Kubernetes cluster, follow these steps to create the necessary working directories and back up the current state of your SAML configuration.

IMPORTANT: The scripts used in this process write to to ~/[Home Directory] by default. To change the location, replace ~/ with the desired location (for example, /opt/) in each script.

From your CLI, navigate to a path where you have permission to create and run the scripts necessary to configure SSO using SAML.

Run the following commands to create the script files:

touch init_backup.sh
chmod +x init_backup.sh
vi init_backup.sh

Open the init.sh script in your code editor and paste the following content into the file:

#!/bin/bash 

set -e

# Create working directories 
echo ""
echo "Creating Working Directory to unpack SSO config template. Note: This directory will be cleaned up after the task runs..."
echo ""
echo "Working DIR 1 Location: ~/working-directory"
mkdir -p ~/working-directory 
echo ""
echo "Working DIR 2 Location: ~/existing-customization-data"
mkdir ~/existing-customization-data

# Create backup of current Core 
echo ""
echo "Creating a backup of existing authentication configuration data..."
kubectl get secret -n kinetic \
  core-customization-secrets \
  -o yaml \
  > ~/existing-customization-data/core-customization-secrets.backup
echo "Backup Completed"

Run the init.sh script using the following command:
```
./init_backup.sh
```
Return to the working directory using the cd command.
```
cd ~/working-directory
```

Retrieving the Helm Chart

Follow these steps to download the helm chart required for the configuration process:

kinetic-core-customizations-job            kinetic-platform-application
kinetic-core-customizations-job-5.0.0.tgz

Navigate to your Installer Dashboard.
From the Application tab, select View Files.
Click Need to edit these files? Click here to learn how.
Click Copy command under Step 1, then paste the command into your CLI and run it.
Run the ls command to see the kinetic-platform directory
```
ls
```
You should receive the response below. If you do not, contact Kinetic Support.
```
kinetic-platform-application
```
Run the cd command to navigate to the core-customizations folder:
```
cd ~/working-directory/kinetic-platform-application/upstream
```
Run the ls command to find the "kinetic-core-customizations-job-5.0.0.tgz" .tar file.
```
ls
```

Copy the .tar file to your working directory.

cp kinetic-core-customizations-job-5.0.0.tgz ~/working-directory

Run the following commands to relocate to the working directory and untar the file:
```
cd ~/working-directory && tar xvf kinetic-core-customizations-job-5.0.0.tgz
```
Run the ls command to confirm the kinetic-core-customizations-job folder was created.
```
ls
```
You should receive the response below. If you do not, contact Kinetic Support.
```
kinetic-core-customizations-job            kinetic-platform-application
kinetic-core-customizations-job-5.0.0.tgz
```

Run the following command to move the "core-customizations" folder to your working directory.

cp -R ~/working-directory/kinetic-core-customizations-job/files/core-customizations ~/working-directory

Run the ls command to confirm the kinetic-core-customizations-job folder was moved correctly.
```
ls
```
You should receive the response below. If you do not, contact Kinetic Support.
```
core-customizations              kinetic-core-customizations-job-5.0.0.tgz
kinetic-core-customizations-job  kinetic-platform-application
```
Run the following command to remove the existing configuration files from the core customization folder:
```
rm -rf ~/working-directory/core-customizations/files/secrets/*
```

Run the following command to create the chart .yaml file:

mv ~/working-directory/core-customizations/Secret.yaml ~/working-directory/core-customizations/Chart.yaml

Retrieve Existing Configuration Files from the Environment

Run the command below to create get_files.sh. This script retrieves the existing configuration files from your environment.

touch ~/existing-customization-data/get_files.sh
chmod u+x ~/existing-customization-data/get_files.sh

vi ~/existing-customization-data/get_files.sh

Copy the following text into get_files.sh:

#!/bin/bash 

set -e 

#Retrive secrets from backup file
echo ""
echo "Retreive secrets in the environment"
echo ""


kubectl get secret -n kinetic core-customization-secrets -o json > core-customization-secrets.json

file='core-customization-secrets.json'
cat "$file" | jq -r '.data | keys[]' | 
while IFS= read -r value; do
    echo "$value"
    kubectl get secret -n kinetic \
        core-customization-secrets \
        -o jsonpath="{.data.${value//./\\.}}" \
        | base64 -d \
        > ~/working-directory/core-customizations/files/secrets/"$value"
done


kubectl get secret -n kinetic core-customization-secrets -o jsonpath="{.data.security\.servicecatalog-test\.properties}" | base64 -d > ~/working-directory/core-customizations/files/secrets/security.servicecatalog-test.properties
kubectl get secret -n kinetic core-customization-secrets -o jsonpath="{.data.security\.servicecatalog-dev\.properties}" | base64 -d > ~/working-directory/core-customizations/files/secrets/security.servicecatalog-dev.properties
kubectl get secret -n kinetic core-customization-secrets -o jsonpath="{.data.security\.properties}" | base64 -d > ~/working-directory/core-customizations/files/secrets/security.properties
kubectl get secret -n kinetic core-customization-secrets -ojsonpath="{.data.keystore\.jks}" | base64 -d > ~/working-directory/core-customizations/files/secrets/keystore.jks

# Check  and View the newly created files 
echo ""
echo "Check created files"
ls ~/working-directory/core-customizations/files/secrets
echo ""
echo "Catting files to view files"
for element in "${secrets[@]}"
do
 echo ""
 file name: "$element"
 echo " "
 cat ~/working-directory/core-customizations/files/secrets/"$element" 
done

echo "File copy complete"
echo "Your next steps are: "
echo " "
echo "1. Update security.properties as seen in the SAML Configuration section of your guide."
echo ""
echo "2. Create secret.space-slug.properties for each Space slug you wish to integrate SAML in. Ensure you have the correct values set up."

Run the cd command to navigate to the "existing-customization-data" directory.
```
cd ~/existing-customization-data
```
Run the following command to execute the "get_existing_configuration_files.sh" script:
```
./get_existing_configuration_files.sh
```

Update the Configuration File to Enable SAML Strategy

Run the following command to navigate to the core customization configuration folder and view the files in the folder:
```
cd ~/working-directory/core-customizations/files/secrets && ls
```

Modify the security.properties file in the configuration folder to enable the SAML strategy by uncommenting the specified properties.
Note: Adding line one is what enables the SAML strategy.

security.strategy=com.kineticdata.core.web.security.strategies.saml.SamlSecurityStrategy
security.keystore.path=/keystore.jks
security.keystore.password=changeit
security.keystore.defaultKey=defaultkey

# Ten years
security.saml.maxAuthnAge=315569520

Create a Space-level configuration file for the Space where you want to enable the SAML strategy. Replace the word "EXAMPLE" with the space slug of the space you want to configure in the below command:
```
cp security.SPACESLUG.properties security.EXAMPLE.properties
```

Open the security.space-slug.properties file to meet your organization's specifications by following the pattern in the example below.
IMPORTANT: The following code is only an example of the security.space-slug.properties file and must be edited for your Space. If you need assistance configuring this file, contact Kinetic Support with your SAML resource available for assistance.

# The security system lets you choose whether the user details can auto-create and auto-update local user data.
# Not all configurers will necessarily support this behavior.
# NB: Successful authentications still require a valid User object within Core Edition.
security.autocreate=true
security.autoupdate=true

security.saml.useForwardedForHeader=true
security.saml.loginPopup=true

## Enable SAML support for this space.
security.saml.enabled=true
## Define the SAML attributes you'll map to email and display name.
security.saml.attributes.email=email
#security.saml.attributes.displayName=FullName
#security.saml.mappings.userAttribute.0.regexMatch=
#security.saml.mappings.userAttribute.0.regexReplace=
#security.saml.mappings.userAttribute.1.name=Office Location
#security.saml.mappings.userAttribute.1.mapping=Office Location
#security.saml.mappings.userAttribute.1.regexMatch=
#security.saml.mappings.userAttribute.1.regexReplace=

#security.saml.mappings.userAttribute.3.name=Site Location
#security.saml.mappings.userAttribute.3.mapping=Site Location


## SAML Service Provider Configuration

## Specify the base URL for the SAML service provider. This must be formatted like this:
## http[s]://hostname[:port]/context/[spaceSlug]/app
## The context will usually be "kinetic". Note that /app does not end in a trailing slash.
## Required: This is required for SAML to effectively build the automated metadata.
## The SP metadata URL is the URL specified plus: /saml/metadata/alias/space-slug
## Example SP Metadata URL: http://localhost:8080/kinetic/acme/app/saml/metadata/alias/acme
## This URL needs to be shared with the IdP.
security.saml.sp.url=https://saml-testing.kinops.io/app

## Specify a custom entity ID for this service provider.
## Optional. The default value is generated as "com:kineticdata:core:SPACESLUG:sp"
security.saml.sp.entityid=https://saml-testing.kinops.io/

## Advanced Service Provider settings:
## Profile used for verification of SSL/TLS connections.
## Values: "pkix" or "metaiop".
## Optional. Default "pkix"
#security.saml.sp.sslsecurityprofile=pkix

## The key used to sign interactions with the SP. This key must be in the keystore and it must
## contain both the public and private key.
#security.saml.sp.signingkey=defaultkey

## The key used to encrypt interactions with the SP. This key must be in the keystore and it must
## contain both the public and private key.
#security.saml.sp.encryptionkey=defaultkey

## Specify the keys for active IDPs.
security.saml.providers=ssocircle

## Example URL-based metadata.
## NB: You must ensure that the SSL certificate or trust certificate is in the global keystore.
security.saml.idp.ssocircle.name=SSO Circle
security.saml.idp.ssocircle.type=url
security.saml.idp.ssocircle.url=https://idp.ssocircle.com/meta-idp.xml

Configure Core Customization Using configure.sh

From your CLI, run the following command:

touch ~/working-directory/configure.sh
chmod u+x ~/working-directory/configure.sh
vi ~/working-directory/configure.sh

Run the following command to update the configure.sh file:

#!/bin/bash 

# Perform upgrade of core customizations 
echo ""
echo "Running the helm upgrade command..."
echo ""
helm upgrade core-customizations ~/working-directory/core-customizations -n kinetic 

# Restart core deployment to apply new changes
echo ""
echo "Roll out Restart Core"
kubectl rollout restart deployment core -n kinetic
kubectl rollout status deployment core -n kinetic -w

Run the following command:
```
cd ~/working-directory/
./configure.sh
```
Navigate to the following URL and download the metadata file. This file contains information you'll need to provide to your SAML provider:
https://${space-slug.example.com}/app/saml/metadata/alias/${space-slug}.
Replace the URL with appropriate space-slug and domain information.
Send this to your SAML provider. Once your SAML provider has configured the appropriate settings, you can test your login.

Test Your Configuration and Clean Up

Open your Kinetic login page. You should be signed in automatically if your SAML connection was configured correctly.
If the test is successful, run the following command to clean up the working directory you created:
```
rm -rf ~/working-directory
```
If the test is unsuccessful, contact Kinetic Support for assistance.
