Hi experts,

I've a small website that required admin log in to manage the content. First deployment, the website put into the URL: www.abc.com/test/admin/login.aspx, this work correctly.

Then I create a sub-domain and put my code into, then brow the URL: test.abc.com/admin/login.aspx, same username/password, same database, but unable to login to the administration module.

The web.config content:

<authentication mode="Forms">
      <forms name="form1" loginUrl="admin/login.aspx" protection="All" path="/" requireSSL="false" slidingExpiration="true" cookieless="UseCookies"/>
    </authentication>

Please help me to resolve it.
D.

Hi dungla,
So what is the error returned? Can you post the detailed errors here?
Lastly, post your application hierarchy here if something is diver from the original domain.

Quick check, try register -aspnet_regiis -i or copy "aspnet_client" folder under your sub-domain. It could be that JS configurations file problem.

I can't, because permission from hosting server is not allow me to do that. But I will ask them to do that

Ok, ask them to grant same settings that perform under your main domain. That should did the trick.

Hi x_com,

Your solution don't work. They said that maybe the problem is the code.

I attached the code as well for your reference.

<form id="form1" runat="server">

Hi dungla,
Sorry for the delay reply.
Ok, try check these following steps to resolve this problem:
1. check their .net framework version that used
2. put the existing code intro try/catch block to inspect further errors.
eg:
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
    {
       try{
 
      if ((Request.QueryString["member"] != null))
        {
            CheckAuthenticateMember();
        }
        else
        {
            CheckAuthenticate();
        }

       }catch (Exception e){
           Response.write("error: " + e.ToString());
        }  
    }
3. check any different configurations or permissions settings that not same with main domain?
4. try check if a simple Response.redirect() work in the application.
eg:
protected void Page_Load(object sender, EventArgs e)
  Response.redirect("http://google.com",false);
}
