您需要从表单切换到Windows身份验证并拒绝匿名用户。

 <  配置 >  
<   system.web an> >  
<   authentication     mode   =  Windows  /  >  
<  授权 >  
<   deny    用户  = ？  /  >  
<   / authorization  >  
<   / system.web  >  
<   / configuration  >  

这应该在用户访问系统时打开一个登录窗口。

I am new for Active Directory authentication. Need to create login using active directory. Please help me with explained example or link where i can learn to create active directory login

<authentication mode="Forms">
      <forms name=".ADAuthCookie" loginUrl="~/Account/LogOn" timeout="15" slidingExpiration="false" protection="All" />
    </authentication>
    <membership defaultprovider="MY_ADMembershipProvider">
      <providers>
        <clear />
        <add name="MY_ADMembershipProvider" type="System.Web.Security.ActiveDirectoryMembershipProvider" connectionstringname="ADService" attributemapusername="sAMAccountName" />
      </providers>
    </membership>

You'll want to switch from forms to windows authentication and deny anonymous users.

<configuration>
  <system.web>
    <authentication mode="Windows"/>
    <authorization>
        <deny users="?"/>
    </authorization>
  </system.web>
</configuration>

This should open a login window when users access the system.
