Sign in a user in an ASP.NET Web App with OpenID Connect and the Microsoft identity platform endpoint

Select the Cloud Shell button on the menu bar at the upper right in the Azure portal.
FTP and local Git can deploy to an Azure web app by using a deployment user. Once you configure your deployment user, you can use it for all your Azure deployments. Your account-level deployment username and password are different from your Azure subscription credentials.
To configure the deployment user, run the az webapp deployment user set command in Azure Cloud Shell. Replace <username> and <password> with a deployment user username and password.
az webapp deployment user set --user-name <username> --password <password>
Create a resource group
az group create --name myResourceGroup --location "West Europe"
Create an App Service plan
az appservice plan create --name myAppServicePlan --resource-group myResourceGroup --sku FREE
Create a web app, replace <app-name> with your app name
az webapp create --resource-group myResourceGroup --plan myAppServicePlan --name <app-name> --deployment-local-git
Get deployment user details from
Get Web App URL
Now navigate to Azure AD > App Registration > New Registration
Now enter the App Name and Web App URL which we captured in step 6 and click Register
Once the App registration is completed, make a note of your Application (client) ID
Now under same page, go to Authenication option then select Token and access id check box to allow token exchange between our app and Azure AD

Now open Cloud Shell once again and do a git clone of our openid sso app

git clone https://github.com/webmagicinformatica/AzureADSSOSampleApp.git

Change directory to following:

cd /AzureADSSOSampleApp/AppModelv2-WebApp-OpenIDConnect-DotNet

Here we need to edit web.config to update following information:
1. Application (client) ID copied in step 10
2. Azure Web App URL copied in step 7
```
vi Web.config
```
3. Edit clientID with Application (client) ID copied in step 10 & redirectURI with Azure Web App URL copied in step 7
  
  Save the change by click ESC followed by :wq!
Now you need to deploy this code to Web App
1. Add change to local git repo
```
git add .
```
2. Commit the changes
```
git commit -m "ready to deploy"
```
3. Add remote origin, you will need deployment user and URL copied in step 6
```
git remote add azure <deploymentLocalGitUrl-from-create-step>
```
4. Push the code
```
git push azure master
```
Now test the application
1. First create a username in Azure AD, if you are not sure how to do it please refer this link
2. Launch Azure Web App URL
3. Enter Azure AD user you just create it’s username & password
4. Once you successfully logged in you will see
