Hello,

I am using ADAL 2.6.2 installed via cocoapods. It works fine for my app until the last release of iOS 11.3. Now the SDK returns the following error: "The network connection was lost."

You can find in the following the logs from ADAL for iOS:

Hi. Thanks for your report. Can you please provide us some more information about the account type you're using? Are you doing 2-factor authentication, when the error happens by any chance?

We're aware of the issue and we have submitted a bug report to Apple on April 3rd. We haven't yet heard back from them, but we're closely tracking this issue. Any additional information you can provide about the nature of the issue will help us in the investigation.

Hello @oldalton,

Thank you for your prompt reply. I am using ADAL for OAuth by calling the the acquireToken method of the SDK. Here a sample code from my app.

`
ADLogger.setLevel(ADAL_LOG_LEVEL_VERBOSE)

    let authContext = AuthEndpoint.authContext()
    let clientId = ProjectConfig.main.adalClientID
    
    authContext?.acquireToken(withResource: ProjectConfig.main.adalResourceID,
                              clientId: clientId,
                              redirectUri: ProjectConfig.main.adalRedirectURL!,
                              userId: "",
                              extraQueryParameters: "domain_hint=my_domain_hint",
                              completionBlock: { (result: ADAuthenticationResult?) in
                                
                                if result?.status != AD_SUCCEEDED {
                                    // handle error
                                    Logger.error("Login: \(String(describing: result?.error.errorDetails))")
                                }
                                else {
                                    //save access token
                                    AuthEndpoint.authorization = "Bearer \(result?.tokenCacheItem.accessToken ?? "")"
                                }
    })

`

Here the authContext function:

`static func authContext() -> ADAuthenticationContext? {

    var error: ADAuthenticationError? = nil
    return ADAuthenticationContext(authority: "https://login.microsoftonline.com/common", error: &error)

}`

I am using domain_hint to force ADAL to display my company gateway instead of displaying the Microsoft login page and then redirect to my company gateway.

I have a button in my app that will trigger the acquireToken function that will display an EMBEDDED webview with the authentication gateway of my company. The user is asked to provide AD username and password. Once confirmed, ADAL will dismiss the webview and returns the access token that I save to use with my api.

This code works for older ios versions, but with iOS 11.3, all the process works until the user confirms his credentials, then ADAL will dismiss the webview but return an error "The network connection was lost." I suspect, the network issue is due to Apple TLS introduced in iOS9. I guess with iOS 11.3, they reinforced the security layer by blocking some requests done by ADAL with may lead to a network connection interruption issue. Please let me know if you have any way that can fix this bug since it is quite blocking for us. We already have few users on the recent iOS version and blocked and the number is growing.

Best regards

We are experiencing the same issue for users with two-factor authentication with Microsoft Authenticator on the same device. It is the switch to background of the app initiating the adal authentication that triggers the error. We have implemented a temporary workaround by having a dummy background task which is alive for 2 minutes, but would very much like a fix for the root cause.

PS from our apps we are using the react-native-ms-adal library https://github.com/samcolby/react-native-ms-adal , but it's a wrapper around this library

Thanks @elsewhat for your comment. I can't see why a background process is needed to keep the app alive in my case since I do not leave the app at all. The authentication process is embedded in the app. Would you please detail more your workaround ?

Might be a slightly different case in iOS 11.3 than yours @medhaj

Our apps lose the connection when the user swaps to the Microsoft authenticator app in order to verify second factor of authentication. The initiating app then enter background.
This is the workaround we've made in AppDelegate.m

+- (void)applicationDidEnterBackground:(UIApplication *)application
+{
+  __block UIBackgroundTaskIdentifier bgTask;
+  bgTask = [application beginBackgroundTaskWithName:@"KeepAlive" expirationHandler:^{
+    NSLog(@"Background task expired");
+
+    // Clean up any unfinished task business by marking where you
+    // stopped or ending the task outright.
+
+    [application endBackgroundTask:bgTask];
+    bgTask = UIBackgroundTaskInvalid;
+  }];
+
+  // Start the long-running task and return immediately.
+  dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
+    NSLog(@"Running background task");
+    [NSThread sleepForTimeInterval:120];
+    NSLog(@"Ended background task");
+
+    [application endBackgroundTask:bgTask];
+    bgTask = UIBackgroundTaskInvalid;
+  });
+}

Hi, ourselves we could only reproduce the issue when backgrounding the application so far. But for certain accounts it's a 100% reproduction when backgrounding the application. For us it seemed that it depends a lot on how the login webpage sends requests (synchronous/asynchronous). So, I'm not surprised that a background task "hack" can relief some of the symptoms.

However, we are also able to reproduce this with a dummy UIWebView or WKWebView project (see attached). The symptoms look a bit different there because of how ADAL uses NSURLProtocol, but it's also the same repro there - in case of ADAL, the authentication fails, because we receive NSURLSession -1005 error and fail the authentication. In case of UIWebView/WKWebView, it just hangs and you can see from the logs that they also get -1005, the webpage never redirects, so the end result is the same and user is unable to login. The reproduction without ADAL and reproducibility only in iOS 11.3 makes us believe that it's an Apple issue or a change they introduced recently. We've submitted a bug report and have reached out to Apple to escalate the issue and get additional guidance.

Meanwhile, please try to login with your user in the attached project (TestWebView113.zip) and check if you see the webview "hanging" and something like this in the log:

2018-04-12 09:15:19.668292-0700 TestWebView113[890:390175] Task <547236A5-E9CE-4DE0-BC5F-9DD1F0805962>.<0> HTTP load failed (error code: -1005 [4:-4])

That way we can make sure it's the same issue. Thanks!

Experiencing the same thing here. Workaround fixed it for now, but would love to see a solid solution for this.

@jimespen

I'm experiencing the same in my Xamarin.iOS app using ADAL.NET. Does anyone know what the C# equivalent to this workaround would be? The type UIBackgroundTaskIdentifier does not exist in Xamarin.iOS.

@pvroosendaal
Copy link

The idea is that you keep your app “alive” when it moves to the background. Is there any mechanism for that in c#?

@pvroosendaal
Copy link

Or maybe reference to a native piece of code? Is that a possibility?

This is the swift version of the workaround. Hope it helps

`

    var bgTask: UIBackgroundTaskIdentifier = UIBackgroundTaskInvalid

    bgTask = application.beginBackgroundTask(withName: "KeepAlive", expirationHandler: {

        application.endBackgroundTask(bgTask)

        bgTask = UIBackgroundTaskInvalid

    })

    DispatchQueue.global().async {

        sleep(120)

        application.endBackgroundTask(bgTask)

        bgTask = UIBackgroundTaskInvalid

    }

`

For my case, it does not help since I am using the Embedded webview in the app. So the app does not enter the background at all.

@pvroosendaal Following the docs (https://docs.microsoft.com/en-gb/xamarin/ios/app-fundamentals/backgrounding/ios-backgrounding-techniques/ios-backgrounding-with-tasks#performing-tasks-during-didenterbackground), I got it to work like so in AppDelegate.cs:

public override void DidEnterBackground(UIApplication application)
{
    base.DidEnterBackground(application);

    nint taskID = UIApplication.SharedApplication.BeginBackgroundTask(() => { });
    new Task(() =>
    {
            Thread.Sleep(20000);
        UIApplication.SharedApplication.EndBackgroundTask(taskID);
    }).Start();

Can this be related to my company web page that should display the login/password fields? Is there any recommendation concerning this webpage to make sure the issue does not come from the page? (Should use SSL? All requests should be asynch?... etc)

Best regards

@medhaj The issue you're seeing here is different from the issue you reported in the first post (network connection lost vs NSURLErrorSecureConnectionFailed). Please make sure that you're running the test app on the same network and with the same Apple Transport Security settings you're using in your main app. The error here indicates the server has SSL issues or you're on the network with issues (e.g. captive proxy, firewall etc), but it's different from the issue you reported in the first post.

ADAL 2.6.3 should solve the issue until Apple releases the fix (https://github.com/AzureAD/azure-activedirectory-library-for-objc/releases/tag/2.6.3)

@medhaj, are you referring to the NSURLErrorSecureConnectionFailed issue? That's a different issue. ADAL 2.6.3 fixes (or works around) connection lost (-1005) issue, when application goes to background.

I am referring the "The network connection was lost." when using ADAL with embedded browser on iOS 11.3. I am still working with our IT department to check if to comes from our internal ADFS service.

@medhaj I recommend you to use CFNetwork diagnostics logging in your project: https://developer.apple.com/library/content/qa/qa1887/_index.html

setenv("CFNETWORK_DIAGNOSTICS", "3", 1);

That way you can see what's up with your connection. If that only started happening on iOS 11.3 and is not clearly a service issue, I suggest you open a bug with Apple for investigation.

The issue we were tracking/fixing was about connection getting lost when app goes to background, which seems different from yours.

@elsewhat we were facing the same issue with react native. In fact the webview on iOS used by react-native is a really old webview (UIWebview). You should use WKWebview ! And everything will work.

@medhaj Maybe you're facing a similar issue..

oldalton commented May 2, 2018

@pcrouillere The issue introduced in iOS 11.3 is also reproducible with WKWebView, because the underlying issue is caused by Apple dropping network connections when app goes to the background. ADAL 2.6.3 works the issue around.

@oldalton, I was having this same "network connection lost" issue, and I upgraded to ADAL 2.6.3 as you recommended and it was resolved. (thank you:) ! )

But now I'm getting these two errors. Could you please advise?

@SuperVixen The issue you're seeing is a known issue and we've previously seen it on macOS: #1026

We're addressing it during our larger code refactoring, but there shouldn't be any implications to the authentication succeeding due to this particular warning you're seeing. If it's not true and you're seeing authentication failing because of that, please let me know.

Yes, you're totally right. The users are getting authenticated successfully. However, they have to manually enter credentials even if they have the Azure Authenticator app and we use brokered authentication. Is this a side effect ?

@oldalton

@SuperVixen I don't think so. I think you're not seeing SSO working.

Are you using brokered authentication (ADCredentialsType == AD_CREDENTIALS_AUTO)?
Are you trying to get SSO working between different apps?

Also, SSO support between different apps through Authenticator app is quite limited for non device joined scenarios. Please refer to documentation here: https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-sso-ios#sso-concepts-in-the-microsoft-identity-platform

@pcrouillere The issue introduced in iOS 11.3 is also reproducible with WKWebView, because the underlying issue is caused by Apple dropping network connections when app goes to the background. ADAL 2.6.3 works the issue around.

This is probably true, but the problem (w/ 2FA enabled on my account) appears when I run the simulator with iOS 9.0 too.

Any idea how to get around this? I'd like to test out this React Native Azure AD library. I also need to verify that my Azure AD app registration is working properly.

@terabytes The issue described here is -1005 - network connection lost. The issue on your screenshot is -1003 and it says that "a server with the specified hostname could not be found". It's a different issue, if you're confident it's an ADAL issue, please open a separate ticket. Looks like a server or DNS issue to me.

D'oh! Thanks a bunch for catching that so quickly, @oldalton. You're my digital hero today! 🥇 I have a support ticket with Microsoft open to get this working so hopefully we'll sort this out soon 🙏

Looks like I might have to fix some network settings...

@oldalton Finally had the time to test the fix in ADAL 2.6.3. Removed the workaround that @elsewhat suggested earlier and I can confirm the connection lost (-1005) issue, when application goes to background, has been fixed. Thanks so much!

Closing this issue as it has been fixed in ADAL 2.6.3.

I used ADAL 2.6.3 and the issue still happens. I believe my issue is similar to OP. In my case, the app never goes to background. We call 'acquireToken' which launches an embedded WebView where user inputs credentials. What we noticed is that although the operation seems to fail (the network lost prompt is shown), seems the token is fetched successfully. Because if we trigger 'acquireToken' again, it just sends us the token with SUCCESS result code. So it's all a bit confusing. Is there any other workaround ??

No luck with the latest version 2.7.6 too. Does this have something to do with how the WebView is embedded in the app.

Objective: we are using company portal app for iOS app deployment and using ADAL, Microsoft Authenticator app for authentication.

Problem : We are facing issue with ADAL with latest iOS version devices below are the specifications.
iOS 13+ & Xcode 11 & Objective C :

We tried with using 'ADAL', '4.0.0' and latest Intune SDK 12.0.18. but after launch the iOS app its not redirecting to the authenticator app to fetch the azure token. before this ADAL update we tested end to end in iOS 12 version devices and it was working.

Also we added com.microsoft.adalcache in Keychain.

Request @oldalton your help on this issue ASAP.

Note : with adal 2.2.7 versions working fine in iOS 12 devices.
Note : we are facing issue with latest iOS 13 and Xcode 11 versions.

Thanks,
Venkat

@venkat-iOS, please make sure you use an iOS 13 compatible ADAL version (4.0.4) and follow steps outlined in this article: https://github.com/AzureAD/azure-activedirectory-library-for-objc/wiki/ADAL-iOS-13-support

This will require you to make some changes for your Info.plist file, as well as your code to support iOS 13.
