Saml integration with angular 8

SAML Integration with Angular 8

SAML (Security Assertion Markup Language) integration with Angular 8 allows you to enable Single Sign-On (SSO) functionality in your Angular application. SSO enables users to authenticate once and access multiple applications or services without having to provide credentials repeatedly.

Here are the steps to integrate SAML with Angular 8:

Step 1: Install Required Packages

First, you need to install the necessary packages for SAML integration:

npm install passport-saml express-session

Step 2: Configure SAML Strategy

You need to configure the SAML strategy in your Angular 8 application. This involves setting up the SAML provider’s details such as the entity ID, identity provider login URL, and certificate settings. You can refer to the documentation of the specific SAML provider for the required configurations.

Here’s an example of configuring the SAML strategy using the library ‘passport-saml’ in Angular 8:

const SamlStrategy = require('passport-saml').Strategy;

  passport.use(new SamlStrategy(
    {
      path: '/login/callback',
      entryPoint: 'https://saml-provider.com/idp/SSOService',
      issuer: 'https://your-angular-app.com/metadata',
      cert: '-----BEGIN CERTIFICATE-----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\njR1PJq3s+dG7cK01e6V0dcw=\n-----END CERTIFICATE-----',

      callbackUrl: 'https://your-angular-app.com/login/callback',
      logoutUrl: 'https://your-angular-app.com/logout'
    },
    function(profile, done) {
      // Handle user authentication and authorization logic here
      // Set user details in session, database, or any other desired storage
      // Call done() to complete the authentication process
      done(null, profile);
    }
  ));

Step 3: Implement Login & Logout Routes

Next, you need to implement the login and logout routes in your Angular 8 application. These routes will handle the SAML authentication and user session management. Here’s an example of implementing these routes using Express.js:

const express = require('express');
  const passport = require('passport');
  
  const app = express();
  
  app.use(passport.initialize());
  app.use(passport.session());
  
  app.get('/login',
    passport.authenticate('saml', { failureRedirect: '/login/error' }),
    function(req, res) {
      res.redirect('/');
    }
  );
  
  app.post('/login/callback',
    passport.authenticate('saml', { failureRedirect: '/login/error' }),
    function(req, res) {
      res.redirect('/');
    }
  );
  
  app.get('/logout', function(req, res) {
    req.logout();
    res.redirect('/');
  });
  
  // Add more routes and application logic as required
  
  app.listen(3000, function() {
    console.log('Server started on port 3000.');
  });

Step 4: Protect Routes with Authentication

Finally, you can protect specific routes or components in your Angular 8 application with authentication. This ensures that only authenticated users can access those routes. You can use Angular’s routing guards such as ‘CanActivate’ or ‘CanActivateChild’ to achieve this.

Here’s an example of protecting a route using a routing guard in Angular 8:

import { Injectable } from '@angular/core';
  import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot, UrlTree, Router } from '@angular/router';
  import { Observable } from 'rxjs';
  
  @Injectable({
    providedIn: 'root'
  })
  export class AuthGuard implements CanActivate {
  
    constructor(private router: Router) { }
  
    canActivate(
      next: ActivatedRouteSnapshot,
      state: RouterStateSnapshot): Observable | Promise | boolean | UrlTree {
        // Check if user is authenticated
        if (userAuthenticated) {
          return true;
        } else {
          // Redirect to login page
          this.router.navigate(['/login']);
          return false;
        }
      }
  }
  
  // In your routing module
  
  import { AuthGuard } from './auth.guard';
  
  const routes: Routes = [
    { path: 'protected', component: ProtectedComponent, canActivate: [AuthGuard] },
    // Other routes
    // ...
  ];

By following these steps, you can integrate SAML with Angular 8 and enable Single Sign-On functionality in your application. Please note that the specific configurations and implementations may vary depending on your SAML provider.
