iOSプログラミングでの認証に問題があります。Windows 2003のIIS6に対して完全に機能するコードがありますが、IIS7を搭載したWindowsServer2008では機能しません。セキュリティオプションは両方のサーバーで同じです(匿名アクセスなしと「統合Windows認証」)。
「didReceiveAuthenticationChallenge」デリゲートのコードは次のとおりです。
-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:
(NSURLAuthenticationChallenge *)challenge
{
//USE STORED CREDENTIALS
Credentials* cred = [[Credentials alloc] init];
NSString* userName = cred.userName;
NSString* pass = cred.pass;
NSString* authMethod = [[challenge protectionSpace] authenticationMethod];
//Kerberos (Negotiate) needs "user@realm" as username
//NTLM Needs domain\\username
if ([authMethod isEqualToString:NSURLAuthenticationMethodNTLM]) {
userName = [NSString stringWithFormat:@"%@%@", @"es\\" , userName];
}
if ([authMethod isEqualToString:NSURLAuthenticationMethodNegotiate]) {
userName = [NSString stringWithFormat:@"%@%@", userName, @"@subdomain.domain.com"];
}
NSLog(@"Auth method in use: %@" , authMethod);
NSLog(@"User: %@" , userName);
NSLog(@"Pass: %@" , pass);
if ([challenge previousFailureCount] <= 1) {
NSLog(@"received authentication challenge");
NSURLCredential *credential;
credential = [NSURLCredential
credentialWithUser:userName
password:pass
persistence:NSURLCredentialPersistenceForSession];
[[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
}
else {
NSLog(@"Authentication error");
NSLog(@"Failed login with status code: %d", [(NSHTTPURLResponse*)[challenge failureResponse]statusCode]);
[[challenge sender] cancelAuthenticationChallenge:challenge];
}
}
