Minimum .NET Provider Implementation Get A User Authenticated And Authorized
Feb 12, 2011
By default ASP.NET MVC setups up the AccountController to use the SqlMembershipProvider, SqlProfileProvider and the SqlRoleProvider. I don't really need everything that brings to the table, in fact, it is more of a hassle to shape my data into that model.What is the minimum I need to implement on the MembershipProvider, RoleProvider and ProfileProvider abstract classes to get authentication and authorization and not break some other dependency that might be there?

I'm using forms authentication in my C# based web site, with the authentication defined in web.config files in the various folders/sub-folders. I want to write a generic administration menu system, that lists all of the admin pages that the use is authorized to open. As I add pages, I want them to automatically show up in the menu. I need to obtain a list/collection of all pages that the active user is authorized to open. Is this possible in ASP.Net 3.5?

I am implementing membership provider. For example, anonymous users are not allowed to acces pages under the folder, namely XXX.
When user clicks to navigate any of those pages I would like to display a popup window. I know I can implement button clikc events. But there are many buttons and links. What is the most effective way to do that?

the Web Part for anonymous user and authenticated user is displayed differently. I faced this problem twise. First time when used Silverlight control in the Web Part and second time when used devexpress control in the Web Part. In both cases problem was with displaying for anonymous user. Silverlight control didn't display. Devexpress control lost it's styles. Both controls had properties that pointed to files. Silverlight control property pointed to the XAP file, and Devexpress control property pointed to the CSS file. It seems to me, that for anonymous user the Web Part cannot find this path or doesn't allow to link to other files.

I am using form authentication in my website. I have a scenario wherein the user is authenticated but the session has timed out. So, i would like to initialize some session variables in Session_Start of Global.asax (First i check if Request.IsAuthenticated=True). For that i required the name of the user who authenticated. On .aspx pages we can get it using Page.User.Identity.Name but how to get it in global.asax page.

I am working on a web application project with a layered architectural style having DAL, BLL, Service Layer and Presentation Layer. It's going to be a Web forms application.
My intent is to try using some of the new features of .Net 3.5 or 4.0.
Currently, I am thinking through different approaches for implementing Authentication in this project.
I have a query regarding the design of the application, particularly Authentication.
In which layer should I have Authentication class? BLL? If I implement the Authentication class in BLL, should I be having an app.config in the same class library project to contain the Database connection string and all.

I've a default.aspx page in my application's root folder. I added a a page in the root of inetpub that redirects requests to the default page. The idea is that the user need only enter the server name to get to the default page. How can I set things up so that all users have access to the default.aspx and that they only have access to the other pages once they've been authenticated?
I am using Windows Integrated Security and the users are being challenged and authenticated properly. I want them to be able to access Default.aspx without any challenges.
(On a side note which may answer this question, when using WIS does the user *allows* have to be challenged? Isn't it possible to pass through their Windows User and ID without the prompt?)

edirect.aspx (set as default document in IIS and simple executes Response.redirect("sites/mercury/default.aspx")

I have a WCF service that will be using basic authentication and would like to be able identify "who" is trying to use the service. I know that the HttpContext.Current is NULL and in the WCF service, but do not know what the alternative is to get the username.
For the website, I can use:
userName = HttpContext.Current.Request.ServerVariables["LOGON_USER"];
How do I get userName in the WCF Service?

I have to select checkboxes besed on group column values. If you see below gridview, column 3 (GroupNo) has 1,1,1,1,2,2,2,2....etc (this column data is not static, will change based on page index. i.e PageIndex =2 may starts with 7,7,7,8,8,8,8,8,9,9,9 etc).
In every sectio/Group User must and should select minimun 2 check boxes. so If user select only one check box we need to show a pop up message as " select One more check box in that particular section" If User skips the message and move to next section we have to show the same message. We have to force the user to select more than one checkbox in the same section.
Mainly our intention is the check boxes whatever user selected in each section/Group belongs to one Category.

I have created a website which has Secure folder in which i have got a form which only "admin role" users can see. Now that form will appear if login is successful and it works great, if password or username is wrong then again the loginForm will appear which works great too.
Now the problem is if the users which are not in "admin role" enter the user name and password correctly, instead of coming back to the login page and showing them the "Not Authenticated" message, it gives me an error that myWebsite/login.aspx is not found. I think this is because the name for my login page is "AdminLoginPage.aspx" and which is not found and hence it shows me the error. I dont know where to change the login Page name to "AdminLoginPage.aspx"

I have Forms authentication setup for an ASP.NET 4.0 application on http://example.com - we'll call it MainApp. I also have an ASP.NET 4.0 app running on http://static.example.com which (let's call it SubApp) doesn't have access to the main app.
Now, SubApp needs to figure out usernames of users who first logged in to the MainApp and then came to SubApp. I thought that it's enough for those two apps to have the same machine keys and for the SubApp to specify in web.config, so it could read the MainApp's authentication cookie and get username from it.
I did a simple test and when I try to hit some page on SubApp it keeps redirecting to http://static.example.com/login.aspx - which doesn't even exist not specified in web.config. Apparently my approach doesn't work, though I don't understand why - main domain's cookie should be accessible on a subdomain, right?
This is how I configure authentication in SubApp:
<authentication mode="Forms">
<forms domain="example.com"/>
</authentication>
<authorization>
<allow users="*"/>
</authorization>

How to check if user is authenticated while using Forms Authentication ..?

I am building a RESTful service using WCF. I basically want to save information about a user when they authenticate to the WCF service. For example I want to save their first name, last name, account number , and password in order to access the information in other requests in the same session. Since this information is sensitive I can not store it in a cookie.
I don't want to use asp.net session state because I plan to run this WCF as a Windows Service. Is there something (class, Assembly) I can use that can save user information and retrieve it per request or do I have to create a custom solution that will create an entry in a database every time a client authenticates to the WCF service.

We have a SSO solution with ADFS for logging into our web app, we also have standard setup that uses authentication with our database. I want to setup a solution that allows for both. So now I am trying to figure out, is there any way for ASP.NET to detect if a user is authenticated with Active Directory so I could do this on the fly? If user is logged in through AD, send through ADFS, else, show login screen. I also realize that this may not work if they are setup to use forms based authentication only after the ADFS process is started.

I got only one ideas to control with the session. When user log into the master page, I insert the current login user and session ID and active status to the SQL table. if user logout manually or close the browser or session expired, I want to change the inactive status. So I can check how many active user are there and the system can prompt the required info to the user. But now, I can't find the soultion to change the inactive
status in above condition.
That doesn't seem right to me. I m sure I 'm making incorrect assumption about this matter.

I am trying to create a httphandler which will intercept a sample pdf file which we have in our website. The httphandler works fine from within my development machine and even my locally published website that if I just try to connect to the test url: [URL] I will get sent to the invalid access page. So pushing it to our IIS6 machine when I try to go to the URL it serves up the PDF document. context.User.Identity.IsAuthenticated is always showing as true. I'm using forms authentication. below is the code I am using as the handler.
public void ProcessRequest(HttpContext context)
{
if (context.User.Identity.IsAuthenticated)
{
string SampleURL = context.Request.AppRelativeCurrentExecutionFilePath;
context.Response.Buffer = true;
context.Response.Clear();
using (FileStream fs = new FileStream(HttpContext.Current.Server.MapPath(SampleURL),FileMode.Open))
{
int length = (int)fs.Length;
byte[] buffer;
using (BinaryReader br = new BinaryReader(fs))
{
buffer = br.ReadBytes(length);
}
context.Response.Clear();
context.Response.Buffer = true;
context.Response.ContentType = "application/pdf";
context.Response.BinaryWrite(buffer);
context.Response.End();
}
}
else
{
context.Response.Redirect(
"~/Error/invalid_access.aspx");
}}
in web.config I have the following for form authentication:
<authentication mode="Forms">
<forms name="Sample.Web" loginUrl="~/Security/" defaultUrl="~/default.aspx" protection="All" timeout="60" path="/" requireSSL="false" slidingExpiration="true" enableCrossAppRedirects="false" cookieless="UseDeviceProfile" domain="">
</forms>
</authentication>
<authorization>
<deny users="?"/>
</authorization>
