Unable to get Forms-based Authentication to work

[Attila]

Hello,

I'm new to ASP.NET, and I'm trying to learn how to implement forms
based authentication. However, I don't know what I'm doing wrong.
While the FormsAuthentication.Authenticate method returns true, after
I call FormsAuthentication.RedirectFromLoginPage I am redirected back
to the login page. I would expect that once the Authenticate method is
run, the user should be authenticated, and the user should be able to
view any page on the site.
Any ideas of what I'm doing wrong? Do I need to set a session
variable? Is there something wrong/missing from my web.config file?

Thanks,
Attila

web.config:

<configuration>
<system.web>
<authentication mode="Forms">
<forms name=".helpdesk_admin_dev"
path="/"
loginUrl="LogIn.aspx"
protection="Encryption"
timeout="300">
<credentials passwordFormat="Clear">
<user name="test" password="1234" />
</credentials>
</forms>
</authentication>

<authorization>
<allow users="test" />
<deny users="?" />
</authorization>
</system.web>
</configuration>

LogIn.aspx code:
protected void Login_Click(Object sender, EventArgs E)
{
string strUsername = Username.Value;
string strPassword = Password.Value;

//Validate the username against the web.config file
if(FormsAuthentication.Authenticate(strUsername, strPassword))
{
FormsAuthentication.RedirectFromLoginPage(strUsern ame, false);
}
else
{
Message.Text = "You did not enter a valid username and password.";
}
}

Please refer to the following MSDN articles for how to implement form based
authentication in asp.net:

Thank you, but I have already seen those links. From what I can tell
my settings are setup correctly, yet it still doesn't appear to be
working. I had thought that my problem was related to my browser,
although it's currently set to accept all cookies.

Hi Buddy!

I had the exact same problem as you did. here is how i solved it:

First, i want you to know i dont fully understand why it works, but it
does. :)

to redirect after login i was using:

Response.Redirect(
FormsAuthentication.GetRedirectUrl(this.Username.T ext,false));

i replaced it with:
FormsAuthentication.RedirectFromLoginPage(this.Use rname.Text,true);

and it now works fine. is it the state cookie param from false to true
or the change of the method, im not sure.

Hi Attila,

Thanks for your update.

Please check whether your server name contains other characters, say,
underscore character ("_"). Based on my research, Internet Explorer blocks
cookies from a server if the its name contains such characters. Please
refer to the following article for detailed information:

PRB: Session Variables Do Not Persist Between Requests After You Install
Internet Explorer Security Patch MS01-055

I look forward to hearing from you.

Have a nice day!

The problem was that my server name contained uderscores. I removed
the underscores from the server name, and it now works. Thanks.

I will be forever in your debt, friend Tian. I've been
beating my head into the wall over this problem for the
past two weeks... and if I hadn't come across this
thread, I'd *still* be beating my head into the wall. My
server name contained an underscore, and when I started
using ASP.NET, I couldn't store cookies or session
variables... which was EXTREMELY frustrating. Thanks
again.
