We have a Azure VM Windows img installed.I need to use that Vm as Self hosted IR , I need to enable the Private end point option in ADF Networking tab. When I foloowed the genneral process like:
Installing the msi file in VM,copying the Authentication key ,while setting up the Server,am getting the error like invalid key .
But when I switched back to public in Networking tab in ADF, The Self IR was running successfully.
I dont need it to connect via public end point.How can we connect via private end point.I dont find any documentation about it.Can anyone help me with the clear steps.

We are creating a UWP app using Xamarin forms and for Login purposes, ADAL has been used. Authentication has been happening successfully when we are connected to VPN. But when we try to run the same app in the Client network where we don’t require VPN, App is not showing ADAL IWA (Integrated Windows Authentication), instead, we are getting the Error message “We can't connect to the service you need right now. Check your network connection or try this again later.” I have attached an image for reference. On investigating further, we found an article about the same issue with the solution in the Microsoft forum (https://learn.microsoft.com/en-us/azure/active-directory/develop/msal-net-uwp-considerations). The solution is to enable the Private Network in the Registry Editor in Authhost.exe in HKEY_LOCAL_MACHINE. On running the below command, we could be able to bypass the issue. But we don’t want to play on editing the registry on each end-user machine or device. So, we tried editing the registry programmatically inside the app, but we got a security exception.
Enabling Private Network Through Command Prompt:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image
File Execution Options\authhost.exe\EnablePrivateNetwork = 00000001
Error while trying to edit Registry Programmatically:
System.Security.SecurityException: 'Requested registry access is not
allowed.'
Reference for Editing Registry Programmatically:
https://codingvision.net/c-edit-registry-keys-or-values
So, we need to understand, what is the best way to address this issue?
I don't want to alter the Registry using the command prompt or
Registry Editor App.
Is it possible to enable private network via AD group policy or Windows OS Settings.
Any other possible way to Enable Private Network
Note:
The same code works fine with Android Environment. The problem is only with Windows.
• There is no group policy existent which changes this option in registry for the private network in ADAL authentication. But you surely can change this registry setting through group policy as it is the only solution to enable private network for ADAL authentication. To do this, please follow the steps below in group policy: -
a) Login to the Group policy server/domain controller and open the group policy management GUI, then select the default domain group policy and edit it.
b) Then go to ‘Computer Configuration --> Preferences-> Windows settings --> Registry --> New --> Registry Wizard’. The registry wizard opens and allows you to connect to the remote computer and select the appropriate registry key, i.e., ‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\authhost.exe\EnablePrivateNetwork = 00000001’
c) Select the correct client system that has the above registry entry present in their system and then select it. Also, please note that the registry browser allows you to select the keys from the hives ‘HKEY_LOCAL_MACHINE’ and ‘HKEY_USERS’ only. Also, if the remote system is unable to connect from the registry finder, please ensure that the system is turned on, access is not blocked by firewall and the remote registry service is not stopped.
d) Once done, the above registry entry is imported into the Group policy console along with the desired path for that registry key in the workspace. Once done, the GPO should be deployed and, in this way, the registry key will be pushed and updated on all the client systems in that domain network.
• You will have to create a new Group policy object and select the appropriate OU from the Group policy server while deploying this registry key if you do not want to deploy it to all the domain networks.
I can create azurerm_app_configuration app configuaration for Azure app configuration.
And can create azurerm_private_endpoint using terraform.
But I didnot find out which terraform function can be used to disable public access, as image below.
Does anyone can help
Just by creating the private endpoint, the public access will be denied. From docs:
By default, when a private endpoint is added to your App Configuration store, all requests for your App Configuration data over the public network are denied. You can enable public network access by using the following Azure CLI command.
However, if you want to control this explicitly, then such a control is not supported in TF. There is github issue about that already:
Support for azurerm_app_configuration public_network_access_enabled
I have created the app service in existing internal app service environment. And then I’m trying to deploy the source code into above app service using Azure DevOps CI & CD pipelines. But, in the release pipeline I’m getting the below error message in Azure DevOps:
Error: Error Code: ERROR_DESTINATION_INVALID
More Information: Could not connect to the remote computer ("xx-xxxx-v1-api-dev.scm.xxx-int-nonp.xxxcloudapps.com"). Make sure that the remote computer name is correct and that you are able to connect to that computer. Learn more at: http://go.microsoft.com/fwlink/?LinkId=221672#ERROR_DESTINATION_INVALID.
Error: The remote name could not be resolved: 'xx-xxxx-v1-api-dev.scm.xxx-int-nonp.xxxxcloudapps.com'
Error count: 1.
Note: I’m using self-hosted agent in the release pipeline. I have tried to access Kudu environment for the above service in the private virtual machine. But, the kudu not opening.
So, please suggest me how to fix the above issue.
Kindly set/add the following to the Application setting and see if it helps.
Name: WEBSITE_WEBDEPLOY_USE_SCM
Value: false
If I have understood your issue correctly (using private link).
For accessing the Kudu console, or Kudu REST API (deployment with Azure DevOps self-hosted agents for example), you must create two records in your Azure DNS private zone or your custom DNS server. Kindly check this document for more details. If you haven't added the records, kindly see if that works.
Name Type Value
mywebapp.privatelink.azurewebsites.net A PrivateEndpointIP
mywebapp.scm.privatelink.azurewebsites.net A PrivateEndpointIP
https://learn.microsoft.com/azure/app-service/networking/private-endpoint#dns
Ensure that the release pipeline is running in the right host. Because the endpoint is private for the SCM too, the DevOps Agent must be in a network with access with the endpoint, so mandatory to use self-hosted Devops Agent.
Kindly see this doc for more details:
https://learn.microsoft.com/azure/app-service/networking/private-endpoint#dns
If the issue still persists, kindly capture a network trace/HAR or client-side HTTP log/review the logs.
P.S. Kindly do not share any PII data on the public forum for your privacy.
I developed a cron trigger azure fuction who needs to search for soe data in my database.
Localy i can connect whit sql server, so i change the connection string in loca.settings.json to connect in azure sql and published the function, but the function cant connect with database.
I need to do something more than configure the local.settings.json?
The local.settings.json is only used for local testing. It's not even exported to azure.
You need to create a connection string in your application settings.
In Azure Functions - click Platform features and then Configuration.
Set the connection string
A function app hosts the execution of your functions in Azure. As a best security practice, store connection strings and other secrets in your function app settings. Using application settings prevents accidental disclosure of the connection string with your code. You can access app settings for your function app right from Visual Studio.
You must have previously published your app to Azure. If you haven't already done so, Publish your function app to Azure.
In Solution Explorer, right-click the function app project and choose Publish > Manage application settings.... Select Add setting, in New app setting name, type sqldb_connection, and select OK.
Application settings for the function app.
In the new sqldb_connection setting, paste the connection string you copied in the previous section into the Local field and replace {your_username} and {your_password} placeholders with real values. Select Insert value from local to copy the updated value into the Remote field, and then select OK.
Add SQL connection string setting.
The connection strings are stored encrypted in Azure (Remote). To prevent leaking secrets, the local.settings.json project file (Local) should be excluded from source control, such as by using a .gitignore file.
https://learn.microsoft.com/en-us/azure/azure-functions/functions-scenario-database-table-cleanup
If you are using entity framework core to make a connection, Other Way of connection to SQL is by using dependency injection from .netcore library.
You can keep the connection string in Azure Key-vault or the config file from there you can read the same using azure function startup class. which need below code setup in your function app.
using Microsoft.Azure.Functions.Extensions.DependencyInjection;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
[assembly: FunctionsStartup(typeof( TEST.Startup))]
namespace TEST
{
internal class Startup : FunctionsStartup
{
public override void Configure(IFunctionsHostBuilder builder)
{
Contract.Requires(builder != null);
builder.Services.AddHttpClient();
var configBuilder = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
.AddAzureKeyVault($"https://XYZkv.vault.azure.net/");
var configuration = configBuilder.Build();
var conn = configuration["connectionString"];
builder.Services.AddDbContext<yourDBContext>(
options => options.UseSqlServer(configuration["connectionString"]));
}
}
}
after that where ever you are injecting this dbcontext, with context object you can do all CRUD operations by following microsoft's entity framework core library documentation.
Having just dealt with this beast (using a custom handler with Linux), I believe the simple way is to upgrade your App to premium-plan, allowing you to access the "Networking" page from "App Service plans". This should allow you to put both sql-server and app in the same virtual network, which probably makes it easier. (but what do I know?)
Instead, if you don't have the extra cash laying around, you can try what I did, and set up a private endpoint, and use the proxy connection setting for your database:
Create a virtual network
I used Address space: 10.1.0.0/16 (default I think)
Add subnet 10.1.0.0/24 with any name (adding a subnet is required)
Go to "Private link center" and create a private endpoint.
any name, resource-group you fancy
use resource type "Microsoft.Sql/Server" and you should be able to select your sql-server (which I assume you have created already) and also set target sub-resource to "sqlServer" (the only option)
In the next step your virtual network and submask should be auto-selected
set Private DNS integration to yes (or suffer later).
Update your firewall by going to Sql Databases, select your database and click "Set Server Firewall" from the overview tab.
Set Connection Policy to proxy. (You either do this, or upgrade to premium!)
Add existing virtual network (rule with any name)
Whitelist IPs
There probably is some other way, but the azure-cli makes it easy to get all possible IP's your app might use: az functionapp show --resource-group <group_name> --name <app_name> --query possibleOutboundIpAddresses
https://learn.microsoft.com/en-us/azure/app-service/overview-inbound-outbound-ips
whitelist them all! (copy paste exercise)
Find your FQDN from Private link center > Private Endpoints > DNS Configuration. It's probably something like yourdb.privatelink.database.windows.net
Update your app to use this url. You just update your sql server connection string and replace the domain, for example as ADO string: Server=tcp:yourdb.privatelink.database.windows.net,1433;Initial Catalog=somedbname;Persist Security Info=False;User ID=someuser;Password=abc123;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=True;Connection Timeout=30;
Also note that I at some point during all of this I switched to TrustServerCertificate=True and now I can't bother to figure out if it does a difference or not. So I left it as an exercise to the reader to find out.
So what we have done here...?
We have forced your function app to go outside the "azure-sphere" by connecting to the private endpoint. I think that if you bounce between azure-services directly, then you'll need some sort of authentication (like logging in to your DB using AD), and in my case, using custom handler and linux base for my app, I think that means you need some trust negotiation (kerberos perhaps?). I couldn't figure that out, so I came up with this instead.
I'm trying to create an Azure Container Instance in the portal with a private image. The validation seems to pass but I can't click OK. The button is disabled.
The private registry is an Azure Container Registry in the same subscription.
Looks like this was resolved on your own after waiting between attempts. For future reference if you need to deploy a private image from the portal you need to include the hostname of the image like "myprivateregistry/nginx:latest".
We've also improved some error handling so deployment failures should also be easier to troubleshoot.
