    Hi Suresh,

    I assume you are using a NSURLConnection to connect to the service? If that's the case you can use the code below as a guide.

    - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge{
    	NSLog(@"Entering didReceiveAuthenticationChallenge");
    	NSInteger count = [challenge previousFailureCount];
        if(count >= 2){
    		// This is the second time the authentication has failed, request review of username/password rather than use settings
    		[connection release];
    		UIAlertView *alert =  [[ UIAlertView alloc ] initWithTitle:@"Error" message:@"Please check username & password" delegate:nil cancelButtonTitle:@"OK"  otherButtonTitles:nil];
    		[alert show];
    		[alert release];
    	} else {
    		NSString *uName = @"Enter username here";
    		NSString *password = @"Enter password here";
    		NSURLCredential* credential = [[NSURLCredential alloc]initWithUser:uName
    		[[challenge sender] useCredential:credential forAuthenticationChallenge:challenge];
    		[credential release];		
    	NSLog(@"Leaving didReceiveAuthenticationChallenge");
