Passing credentials in IP address


I am trying to access media directly from a network share on our local network. The problem is that I need to pass windows credentials with the url. I have tried impersonation with logon type 9, and I have tried passing the credentials in the url like this:

@"\\username:password@ip\share_name\path\filename.mkv"

I am trying to access the media in a windows media player in a winform project, and the player just loads something and goes to a ready state. When typing the address in explorer it asks for credentials, which is what I expected, but how do I do that in my case? I feel like I have tried everything..

token = IntPtr.Zero;
LogonUser("Username", "NAS-IP", "Password",
            9, 0, ref token);
person = new WindowsIdentity(token).Impersonate();

axWindowsMediaPlayer1.URL = @"\\ip\camera_share\axis-ACCC8E7B9050\20170712\08\20170712_085720_39AA_ACCC8E7B9050\20170712_08\20170712_085720_0092.mkv";

EDIT

For some reason it works if I use the machinename/servername as address in the media player url. This is just not that efficient if the client only knows the ip of the server not the name.

token = IntPtr.Zero;
LogonUser("username", "serverip", "password",
            9, 0, ref token);
person = new WindowsIdentity(token).Impersonate();
axWindowsMediaPlayer1.URL = @"\\servername\camera_share\axis-ACCC8E7B9050\20170719\10\20170719_100732_8084_ACCC8E7B9050\20170719_10\20170719_100732_E5A7.mkv";

Any idea on how to work around that?


Solution

  • After some extensive research I found a very viable answer in the thread: How to provide user name and password when connecting to a network share

    Luke Quinane made the following code:

    public class NetworkConnection : IDisposable
    {
        string _networkName;
    
        public NetworkConnection(string networkName, 
            NetworkCredential credentials)
        {
            _networkName = networkName;
    
            var netResource = new NetResource()
            {
                Scope = ResourceScope.GlobalNetwork,
                ResourceType = ResourceType.Disk,
                DisplayType = ResourceDisplaytype.Share,
                RemoteName = networkName
            };
    
            var userName = string.IsNullOrEmpty(credentials.Domain)
                ? credentials.UserName
                : string.Format(@"{0}\{1}", credentials.Domain, credentials.UserName);
    
            var result = WNetAddConnection2(
                netResource, 
                credentials.Password,
                userName,
                0);
    
            if (result != 0)
            {
                throw new Win32Exception(result, "Error connecting to remote share");
            }   
        }
    
        ~NetworkConnection()
        {
            Dispose(false);
        }
    
        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }
    
        protected virtual void Dispose(bool disposing)
        {
            WNetCancelConnection2(_networkName, 0, true);
        }
    
        [DllImport("mpr.dll")]
        private static extern int WNetAddConnection2(NetResource netResource, 
            string password, string username, int flags);
    
        [DllImport("mpr.dll")]
        private static extern int WNetCancelConnection2(string name, int flags,
            bool force);
    }
    
    [StructLayout(LayoutKind.Sequential)]
    public class NetResource
    {
        public ResourceScope Scope;
        public ResourceType ResourceType;
        public ResourceDisplaytype DisplayType;
        public int Usage;
        public string LocalName;
        public string RemoteName;
        public string Comment;
        public string Provider;
    }
    
    public enum ResourceScope : int
    {
        Connected = 1,
        GlobalNetwork,
        Remembered,
        Recent,
        Context
    };
    
    public enum ResourceType : int
    {
        Any = 0,
        Disk = 1,
        Print = 2,
        Reserved = 8,
    }
    
    public enum ResourceDisplaytype : int
    {
        Generic = 0x0,
        Domain = 0x01,
        Server = 0x02,
        Share = 0x03,
        File = 0x04,
        Group = 0x05,
        Network = 0x06,
        Root = 0x07,
        Shareadmin = 0x08,
        Directory = 0x09,
        Tree = 0x0a,
        Ndscontainer = 0x0b
    }
    

    Which I could use like this:

    using (new NetworkConnection(@"\\IP", new NetworkCredential("Username", "Password", System.Net.NetworkInformation.IPGlobalProperties.GetIPGlobalProperties().DomainName)))
    {
         axWindowsMediaPlayer1.URL = @"\\IP\camera_share\axis-ACCC8E7B9050\20170719\10\20170719_100732_8084_ACCC8E7B9050\20170719_10\20170719_100732_E5A7.mkv";
    }
    

    Thanks Luke!
