Try to use sharedCredentialStorage for all domains you need to authenticate.
Here is working sample for UIWebView it was tested against Windows IIS having only BasicAuthentication enabled
This is how to add your site credentials:
NSString* login = @"MYDOMAIN\\myname";
NSURLCredential *credential = [NSURLCredential credentialWithUser:login
password:@"mypassword"
persistence:NSURLCredentialPersistenceForSession];
NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc]
initWithHost:@"myhost"
port:80
protocol:@"http"
realm:@"myhost" // check your web site settigns or log messages of didReceiveAuthenticationChallenge
authenticationMethod:NSURLAuthenticationMethodDefault];
[[NSURLCredentialStorage sharedCredentialStorage] setDefaultCredential:credential
forProtectionSpace:protectionSpace];
[protectionSpace release];
Edit: same code in Swift 4
let login = "MYDOMAIN\\myname"
let credential = URLCredential(user:login, password:"mypassword", persistence:.forSession)
let protectionSpace = URLProtectionSpace(host:"myhost", port:80, protocol:"http", realm:"myhost", authenticationMethod:NSURLAuthenticationMethodDefault)
URLCredentialStorage.shared.setDefaultCredential(credential, for:protectionSpace)
Your webView is supposed to work now, if it does not work use next code to debug, especially check log messages of didReceiveAuthenticationChallenge.
#import "TheSplitAppDelegate.h"
#import "RootViewController.h"
@implementation TheSplitAppDelegate
@synthesize window = _window;
@synthesize splitViewController = _splitViewController;
@synthesize rootViewController = _rootViewController;
@synthesize detailViewController = _detailViewController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
// Add the split view controller's view to the window and display.
self.window.rootViewController = self.splitViewController;
[self.window makeKeyAndVisible];
NSLog(@"CONNECTION: Add credentials");
NSString* login = @"MYDOMAIN\\myname";
NSURLCredential *credential = [NSURLCredential credentialWithUser:login

[protectionSpace release];

The final solution for WebView authentication was based on custom protocol implementation. All protocols registered as a stack, so if you redefine HTTP protocol it would intercept all requests coming from webView, so you have to check attributes assotiated with incoming request and repack it into new request and send it again via your own connection. Since you are in stack, your request immidiatly comes to you again and you have to ignore it. So it goes down protocol stack to real HTTP protocol implementation, since your request is not athenticated you'll get authenticaiton request. And after authenticaiton you'll get a real response from server, so you repack response and reply to original request received from webView and that's it.
Don;t try to create new requests or responses bodies, you have to just resend them. The final code would be aproximetly 30-40 lines of code and it is quite simple, but requires a lot of debuging and tetsing.
Unfortunatlly I cannot provide code here, since I am assigned to different project already, I just wanted to say that my post is wrong way, it stucks when user changes password.
