Windows authentication or user login needed

    Windows authentication or user login needed

    Hi,  I looking for a solution to get users authenticated via their windows login info.
    I need to get the username if it is an authenticated windows user and if this info is not available then get login via the normal login page. 
    In VB I only know to do get logon things via this code:
    LogonVariable = UCase(Request.ServerVariables("LOGON_USER"))
     
    How would I be able to change Cute Chat so that it would grab the windows login info if available ?
    And then thensecond part, if this is not available, get users to the login page ?
     
    Many thanks!

    Re: Windows authentication or user login needed

    in the integration code , you can do something like :
     
    public override AppChatIdentity GetLogonIdentity()
    {
      string name=HttpContext.Current.Request.ServerVariables["LOGON_USER"];
      if(name==null||name=="")return null;
      return new AppChatIdentity(name,false,ToUserId(name),HttpContext.Current.Request.UserHostAddress);
    }
     
    and you also need to return some information for the function :
     
    public override bool GetUserInfo(string loginName, ref string nickName, ref bool isAdmin)
    {
        //change this code to better
        nickName=loginName;
        isAdmin=false;
        return true;
    }
     
    Regards , Terry.

    Would it be possible to get a a complete generic file with this code added. I don't know squat about asp.net. Nice upgrade by the way.

    Re: Windows authentication or user login needed

    You can try this  Global.asax :
     

    <%@ Application Language="C#" %>
    <%@ Import Namespace="CuteChat" %>

    <script runat="server">

     void Application_Start(object sender, EventArgs e) {

            ChatProvider.Instance = new AspNetChatProvider();
            ChatSystem.Start(new AppSystem());
           
     }

        public class AspNetChatProvider : ChatProvider
        {
            public override string GetConnectionString()
            {
                return System.Configuration.ConfigurationManager.ConnectionStrings["SiteSqlServer"].ConnectionString;
            }

            public override AppChatIdentity GetLogonIdentity()
            {
                string fullname=HttpContext.Current.Request.ServerVariables["LOGON_USER"];
                if (fullname == null || fullname == "")
                    return null;

                string nickname = fullname.Split('\\')[1];

                return new AppChatIdentity(nickname, false, ToUserId(nickname), HttpContext.Current.Request.UserHostAddress);
            }
           
            public override string  FindUserLoginName(string nickName)
            {
                return nickName;
            }
            public override bool  GetUserInfo(string loginName, ref string nickName, ref bool isAdmin)
            {
                if (loginName == null || loginName == "")
                    return false;

                try
                {
                    System.Security.Principal.SecurityIdentifier sid = (System.Security.Principal.SecurityIdentifier)new System.Security.Principal.NTAccount(loginName).Translate(typeof(System.Security.Principal.SecurityIdentifier));
                }
                catch
                {
                    return false;
                }

                nickName = loginName;

                if (nickName == "Administrator")
                {
                    isAdmin = true;
                }
               
                return true;
            }

            public override bool ValidateUser(string username, string password)
            {
                return false;
            }
        }

       
    </script>

    Re: Windows authentication or user login needed

    Downloaded app again, replace web folder, added code to global.asax....same error. It may have a lot to do with the fact that I don't know what I'm doing but I'm not sure.
