Hi, Joe:

When I use windows authentication, the login user did not be added to the user list. I login use the domain Administrator user.

So when i view a thread in forums, error occurs:

below code in Thread.aspx.cs

//////////////////////////////////////////////////////////////

private void Page_Load(object sender, EventArgs e)
{

...

if(User.Identity.IsAuthenticated)
{
SiteUser u = SiteUtils.GetCurrentSiteUser();
this.userID = u.UserId; //Because u is null, so u.UserId error.
}

...

}

//////////////////////////////////////////////////////////////

I did not find the code to add the windows authentication user to the mp_Users table.

Thanks!

Hi, joe

You are right, when i clear the cookies, it is ok.

I try all authentication types, include form authentication、windows authentication、ldap authentication.

I have ever cleared the users from table mp_Users by hand,  so when I use back windows authentication again, the ie cookie is already exist, so the user will not be added to the system again.

When read Web/Components/AuthHandlerHttpModule.cs，I clear the cookie, it works!

It is my problem.

Thanks for your help!
