ADAuthenticationErrors are provided in all callbacks in the ADAuthenticationResult's error property when an error occurs. They can be used to have the application display more more informative errors to the user, however ADAL Error messages are not localized. All ADAuthenticationErrors are logged with the ADAL logger as well.
Application, using the ADAL library crashes with the following exception:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '+[NSString isStringNilOrBlank:]: unrecognized selector sent to class 0x13dc800'
Solution: Make sure that you add the -ObjC flag to "Other Linker Flags" build setting
of the application. For more information, see Apple documentation for using static
libraries:
https://developer.apple.com/library/ios/technotes/iOSStaticLibraries/Articles/configuration.html#//apple_ref/doc/uid/TP40012554-CH3-SW1.
Log ins are not persisting, Cache always returns empty
Solution: Either add the "com.microsoft.adalcache" keychain sharing entitlement to your application, or disable keychain sharing by passing in your application's bundle id in ADAuthenticationSettings:
[[ADAuthenticationSettings sharedInstance] setSharedCacheKeychainGroup:nil];ADAL keeps returning SSL errors in iOS 9 and later
iOS 9 added App Transport Security (ATS). ATS restricts apps from accessing the internet unless they meet several security requirements including TLS 1.2 and SHA-256. It also prevents network traces that rely on self signed certs to crack SSL from working. Disabling ATS must be done in the Application's info.plist file, see documentation on the NSAppTransport info.plist key for more information.
