azure-activedirectory-library-for-objc: ADAL is not working for iOS 11.3

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:

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful. 2018-04-10 19:07:24.984926+0200 NICE[37405:1100457] [Snapshotting] Snapshotting a view (0x7b5000078c00, UIInputSetHostView) that has not been rendered at least once requires afterScreenUpdates:YES. 2018-04-10 19:07:32.140729+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32 - 4FFCF554-B7CD-49C1-A523-796AC79583DB] VERBOSE: -webAuthShouldStartLoadRequest host: unknown host 2018-04-10 19:07:32.147095+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32 - 4FFCF554-B7CD-49C1-A523-796AC79583DB] VERBOSE: +[ADURLProtocol canInitWithRequest:] handling host - host: unknown host 2018-04-10 19:07:32.148132+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32] VERBOSE: +[ADURLProtocol canInitWithRequest:] handling host - host: unknown host 2018-04-10 19:07:32.170958+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32] VERBOSE: +[ADURLProtocol canInitWithRequest:] handling host - host: unknown host 2018-04-10 19:07:32.171367+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32] VERBOSE: +[ADURLProtocol canonicalRequestForRequest:] - host: unknown host 2018-04-10 19:07:32.172327+0200 NICE[37405:1100687] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32] VERBOSE: -[ADURLProtocol startLoading] - host: unknown host 2018-04-10 19:07:32.282985+0200 NICE[37405:1100603] Task <69459BE9-52A9-4883-986A-22C0EEA32A70>.<6> finished with error - code: -999 2018-04-10 19:07:32.284828+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32 - 4FFCF554-B7CD-49C1-A523-796AC79583DB] VERBOSE: -webAuthShouldStartLoadRequest host: unknown host 2018-04-10 19:07:32.286150+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32] VERBOSE: +[ADURLProtocol canInitWithRequest:] handling host - host: unknown host 2018-04-10 19:07:32.286658+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32] VERBOSE: +[ADURLProtocol canInitWithRequest:] handling host - host: unknown host 2018-04-10 19:07:32.287734+0200 NICE[37405:1100687] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32] VERBOSE: -[ADURLProtocol stopLoading] - host: unknown host 2018-04-10 19:07:32.289246+0200 NICE[37405:1100613] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32] VERBOSE: +[ADURLProtocol canInitWithRequest:] handling host - host: unknown host 2018-04-10 19:07:32.290172+0200 NICE[37405:1100687] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:32] VERBOSE: -[ADURLProtocol startLoading] - host: unknown host 2018-04-10 19:07:32.314930+0200 NICE[37405:1100613] TIC Read Status [9:0x7b30000a0b00]: 1:54 2018-04-10 19:07:32.444425+0200 NICE[37405:1100613] TIC Read Status [10:0x7b300019d580]: 1:54 2018-04-10 19:07:32.519821+0200 NICE[37405:1100885] TIC Read Status [11:0x7b30001b0b40]: 1:54 2018-04-10 19:07:33.117761+0200 NICE[37405:1100613] TIC Read Status [12:0x7b30001afac0]: 1:54 2018-04-10 19:07:33.120521+0200 NICE[37405:1100613] Task <A8565F46-508F-4A96-9C85-9776C335CCA6>.<7> HTTP load failed (error code: -1005 [4:-4]) 2018-04-10 19:07:33.121252+0200 NICE[37405:1100603] Task <A8565F46-508F-4A96-9C85-9776C335CCA6>.<7> finished with error - code: -1005 2018-04-10 19:07:33.122030+0200 NICE[37405:1100591] NSURLConnection finished with error - code -1005 2018-04-10 19:07:33.123830+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:33 - 4FFCF554-B7CD-49C1-A523-796AC79583DB] ERROR: -webAuthDidFailWithError error code -1005 2018-04-10 19:07:33.124978+0200 NICE[37405:1100687] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:33] VERBOSE: -[ADURLProtocol stopLoading] - host: unknown host 2018-04-10 19:07:33.125535+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:33 - 4FFCF554-B7CD-49C1-A523-796AC79583DB] ERROR: Error raised: (Domain: “NSURLErrorDomain” Code: -1005 ProtocolCode: “(null)” 2018-04-10 19:07:33.661391+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:33 - 4FFCF554-B7CD-49C1-A523-796AC79583DB] INFO: ##### END failed { domain: NSURLErrorDomain code: -1005 protocolCode: (null) idtype = RequiredDisplayableId authority host: login.microsoftonline.com ##### 2018-04-10 19:07:33.666603+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:33] WARNING: Removing all items for client 2018-04-10 19:07:33.668648+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:33] INFO: Failed to get a wipe data or it does not exist 2018-04-10 19:07:33.669012+0200 NICE[37405:1100457] ADAL 2.6.2 iOS Sim 11.3 [2018-04-10 17:07:33] INFO: No items were found for query `

@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.

@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

@supervixen The issue you’re seeing is a known issue and we’ve previously seen it on macOS: https://github.com/AzureAD/azure-activedirectory-library-for-objc/issues/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.

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)

@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();
}
