Yes , you can .
You must implement two classes and register it using the CuteChatConfig.exe
for the CuteSoft.Chat.UserAdapter.GetUserUniqueName()
you could
return System.Security.Principal.WindowsIdentity.GetCurrent().Name
for the CuteSoft.Chat.DataProvider.ListUserUniqueName() and other methods
, you need to use the ActiveDirectory API to list the windows members .
(I wrote one for the 1.1 before , here is the code )
namespace CuteChat.WinAuthLib
{
using System;
using System.Collections;
using System.Collections.Specialized;
using System.Configuration;
using System.Data;
using System.Data.SqlClient;
using System.DirectoryServices;
using CuteChat;
using CuteChat.SqlServer;
public class WinAuthDataProvider : SqlDataProvider
{
public WinAuthDataProvider(string connectionstring):base(connectionstring)
{
}
private DirectoryEntry OpenPath()
{
NameValueCollection appSettings=ConfigurationSettings.AppSettings;
//WinNT: case sensitive
//"WinNT://." , WinNT://DOMAIN/SERVER , WinNT://WORKGROUP/PCNAME
string path=appSettings["WinAuthPath"];
string username=appSettings["WinAuthUsername"];
string password=appSettings["WinAuthPassword"];
if(path==null)path="WinNT://.";//local
if(username==null)
return new DirectoryEntry(path);
return new DirectoryEntry(path,username,password);
}
public override string[] ListUserUniqueName()
{
ArrayList names=new ArrayList();
using(DirectoryEntry nt=OpenPath())
{
foreach(DirectoryEntry child in nt.Children)
{
if(child.SchemaClassName=="User")
{
names.Add(child.Properties["Name"].Value);
}
}
}
return (string[])names.ToArray(typeof(string));
}
public override UserInfoData GetUserInfo(string useruniquename)
{
using(DirectoryEntry nt=OpenPath())
{
foreach(DirectoryEntry child in nt.Children)
{
if(child.SchemaClassName=="User")
{
string name=Convert.ToString(child.Properties["Name"].Value);
if(string.Compare(name,useruniquename,true)==0)
{
bool isadmin=string.Compare(useruniquename,ConfigurationSettings.AppSettings["AdminLoginName"],true)==0;
string fullname=Convert.ToString(child.Properties["FullName"].Value);
if(fullname==null||fullname.Length==0)
fullname=name;
return new UserInfoData(useruniquename,fullname,isadmin);
}
}
}
}
throw(new Exception("User not found"));
}
public override bool IsUserNickNameExists(string nickname)
{
using(DirectoryEntry nt=OpenPath())
{
foreach(DirectoryEntry child in nt.Children)
{
if(child.SchemaClassName=="User")
{
string name=Convert.ToString(child.Properties["Name"].Value);
string full=Convert.ToString(child.Properties["FullName"].Value);
if(string.Compare(name,nickname,true)==0)
return true;
if(string.Compare(full,nickname,true)==0)
return true;
}
}
}
return false;
}
}
}
Today I am busy , please wait , I will write one two days later .
