How to integrate SSO for Php codeigniter application
Hi, I have one independent application developed in PHP codeigniter framework but how to integrate or provide SAML single sign on option in AZURE AD
Integrating SSO (Single Sign-On) with Azure AD into a PHP CodeIgniter application involves several steps. Here's a general guide to help you get started:
Register your Application in Azure AD:
- Log in to the Azure portal.
- Navigate to Azure Active Directory > App registrations > New registration.
- Provide a name for your application, and choose the appropriate Supported account types.
- For the Redirect URI, specify the URL where Azure AD will send the authentication response (e.g., https ://yourdomain.com/auth/saml_callback).
- Once the application is registered, note down the Application (client) ID and Tenant ID. You'll need these later.
Configure SAML-based SSO in Azure AD:
- In the Azure portal, navigate to your registered application.
- Go to Authentication > Add a platform > SAML-based SSO.
- Enter the appropriate Sign-on URL and Identifier (these should correspond to your application).
- Upload the SAML Signing Certificate.
- Save your changes.
Install SAML Library:
- PHP does not have built-in support for SAML, so you'll need to use a library. One commonly used library is simplesamlphp.
- Install simplesamlphp library in your project. You can either download it manually or use Composer.
Configure simplesamlphp:
- Configure simplesamlphp by providing the necessary settings for Azure AD.
- You'll need to configure metadata for Azure AD. This includes the Azure AD Identifier, Certificate fingerprint, etc.
Implement SSO in CodeIgniter:
- Create a controller and views to handle SAML authentication.
- Use the simplesamlphp library to initiate the authentication process.
- Define routes in CodeIgniter to handle authentication callbacks.
Test your Integration:
- Ensure that your CodeIgniter application redirects users to Azure AD for authentication.
- Verify that users can log in using their Azure AD credentials.
- Test the SSO flow thoroughly to ensure it works as expected.
Don't forget to conduct thorough testing, including penetration testing and code reviews, and implement top https://www.webomindapps.com/codeigniter-security-best-practices.html to avoid any security weaknesses before deployment.
