Cookies - How To Handle "Remember Me" In The Membership Provider
Jun 25, 2010
Ive written a custom membership provider for my ASP.Net website.
Im using the default Forms.Authentication redirect where you simply pass true to the method to tell it to "Remember me" for the current user.
I presume that this function simply writes a cookie to the local machine containing some login credential of the user.
What does ASP.Net put in this cookie? Is it possible if the format of my usernames was known (e.g. sequential numbering) someone could easily copy this cookie and by putting it on their own machine be able to access the site as another user?
Additionally I need to be able to inercept the authentication of the user who has the cookie. Since the last time they logged in their account may have been cancelled, they may need to change their password etc so I need the option to intercept the authentication and if everything is still ok allow them to continue or to redirect them to the proper login page.

We are facing a very strange issue, which is senseless. We have dedicated test server and live server. cookies work properly both on IE and firefox locally. when we deploy it on dedicated test server, It also work their on both browsers. But as soon we deploy it to our live dedicated server, it works properly on IE, but firefox does not remember cookies. Here i want to tell you one more thing that both test setver and live server configurations are same. they both are 64 bit machines. Waiting for ur responses.

I have watched the how to video on Creating a Custom Membership provider. So far it works great. My login control interacts well with it etc. Now i've created a Custom Role Provider. I've created a class that inherits the RoleProvider base class and i've added code to each Sub. My question is, what is the best way to implement the role provider, considering I get the Roles etc from the database?

I am trying to build an application that
1. user can login by their AD account and password.
2. AD account can be assigned to different group.
I know there is a training video - [URL] to teach how to use the tool to provision the membership schema to SQL server for Forms authentication. but how can I use AD authentication with this?

<profile>
<providers>
<clear/>
<add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/"/>
</providers>
<properties>
<add name="FirstName"/>
<add name="LastName"/>
</properties>
</profile>
I have the code snippet above in my webconfig file. I am attempting to set the FirstName property in codebehind on a register.aspx page. Like this:
Profile.FirstName = ((TextBox)RegisterUser.CreateUserStep.ContentTemplateContainer.FindControl("FirstName")).Text;
VS says Profile is in System.Web.Profile Namespace. I then use it like this "System.Web.Profile.FirstName", but says first name does not exist in System.Web.Profile.FirstName namespace.
How do I set the property and later retrieve it?

Why remember me doesn't work? As you can see in picture below Expire date is at the end of session although I set expiration to 1 month. This is my login button codes
protected void btn_login_Click(object sender, EventArgs e) {
if (!Page.User.Identity.IsAuthenticated) {
if (GetMemberAuthenticate(txt_uname.Text, FormsAuthentication.HashPasswordForStoringInConfigFile(txt_pass.Text, "MD5")))
[Code] ....
And this is in global.asax
And in web.config
<authentication mode="Forms">
<forms loginUrl="Default.aspx" defaultUrl="~/" name="MyCookieName"
slidingExpiration="true"
timeout="43200"></forms>
</authentication>
Â

According to the RFC, individual cookies in the "Cookie" HTTP header may be separated by commas as well as by semicolons. However, ASP.NET does not parse the commas case correctly - it does not count comma as a separator, but considers it just part of the value.
For exampleIf a client sends header Cookie: a=b, c=d, then the ASP.NET application will see just one cookie named "a" with value "b, c=d".As a special case, the same thing happens when the client sends several Cookie headers (one for each cookie) instead of combining all cookies in one header. From HTTP perspective, this is completely valid, and in such case the effective value of the header should be concatenation of the values of all its instances separated by commas.Does anybody know a workaround (or maybe a fix?) for this? I absolutely need to get this working, because I don't control the client.P.S. It is ironic that, according to this thread, the .NET built-in HTTP client's (aka HttpWebRequest) behavior is just the opposite, and also causes problems. :-)

This thing has just came to my head and I wanna share it.Note : I could easily test it but I am being lazy here to see if anybody has ever experienced something like that before.Let's assume that I have a web site which built-in membership structure of asp.net has been implemented on. What will happen to asp.net membership if the client browser blocks cookies? Does framework throw an exception when a user tries to log in or do something else?

I am building my first asp.net app from scratch. I have two different membership providers. One is a basic sql provider while the other is active directory. The user "role" is determined by how the user logs in. I want to use the Role Manager functionality of asp.net but I don't want to build the whole role provider part when I really don't have "roles" in my application, I have two membership types.
Is there a way to set the role of the user through the membership provider at login or in some way mark a logged in user as having been authenticated by sql or AD?
This is my first asp.net app, am I even thinking about this the right way?

I am using SQL Membership Provider to create user accounts for my web site and for some reason, the CreateDate and LastLoginDate fields are NOT saving the current time of my machine when I add a new user to the website. It is showing the previous day's date and the time is displayed as PM when it's AM and vise-versa in the CreateDate and LastLoginDate fields in aspnet_Membership table. I am developing and running the website via localhost on my laptop using IIS 7 (Windows 7). Does this have anything to do with my laptop's clock settings or is there something I need to configure in the web.config file or in IIS.

The default implementation is not very appropriate normally and I haven't seen so far a good implementation of a custom membership provider, probably because this is not possible.

i am planing an application that needs to handle different client logins. A user should be able to login under each clients url.The project will have a start page and multiple (database generated) client URLs.www.domain.com/ClientA www.domain.com/ClientB www.domain.com/ClientC
I failed using MVC Routes to build up such a scenario with dynamically clients so i used an MVC area for the client space:www.domain.com/clients/ClientA www.domain.com/clients/ClientB www.domain.com/clients/ClientC Is there any client support for membership providers? All i found is made for a single client environment. I would love to take advantage of the mvc buildin attributes for authentication..

In a standard ASP.NET MVC template application that is created by default in Visual Studio when starting a new ASP.NET MVC application there is already a built-in membership / authentication / authorization system.
Using web search one can find lots of info about how to work with a built-in ASP.NET membership system, but very often this material is a bit of an old and refer to ASP.NET only, not mentioning ASP.NET MVC framework.
Just for example:
http://msdn.microsoft.com/en-us/library/ms998347.aspx#paght000022%5Fmembershipapis
or http://www.4guysfromrolla.com/articles/091207-1.aspx
To what extent all that applies to ASP.NET built-in membership system applies also to ASP.NET MVC ready template membership system?
