Web Forms :: Web Parts And Anonymous User And Authenticated User Is Displayed Differently?

Mar 21, 2011

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.

How To Auto Redirect A Forms Authenticated User To An NT Site If They Have Equivalent Credentials On The Domain

Dec 9, 2010

I have a requirement that whenever a user logs onto a website using forms based authentication [FBA] that the site checks whether they have a related domain NT user record. There will be a matching lookup table between the ASPNETDB membership database and related domain accounts for users.Whenever an FBA user logs in and a related domain account is located then the member should be redirected to an alternative site / URL which is Windows NT authenticated rather than FBA. Before transferring them I would like to be able to pre authenticate them on the windows domain rather than an additional NT Login dialog box coming up and asking them to enter the related NT credentials.Is it possible to programatically preauthenticate using NT credentials before redirecting a user to an NT authenticated site?Note: This isn't technically a single sign on style scenario. The FBA / NT authenticated sites are not related other than the relationship between the original FBA credentials and the NT credentials lookup.

Security :: Why A Forms-authenticated User Needs To Login Again To Role Subfolders In An IIS Server Environment

May 7, 2010

Followed the code sample of Chapter 10 (Logging in) of the Book, Microsoft ASP.NET 2.0, I created an ASP.NET 3.5 website with Forms Authentication. The sample code used Website Administration Tool (WAT) to manage the users, roles, and authorization.When running in the ASP.NET Development server environment, I can first login, then click to open the links for each for the 3 roles.

However when running the sample code in the IIS server environment, I can login but can not open the links for the role subfolders.Clicking each link popped up an error message for opening a login.aspx from the specific subfolder. I don't have a Login.aspx file in each subfolder.The 3 role subfolders were configured as the virtual folders in the IIS Server. Why the sample code worked fine inASP.NET Development server environment, but got an error message from theIIS Server environment? Why an authenticated user can not open the subfolder homepage?

Security :: Grant Access To Default Page For All Users - Authenticated & Non-Authenticated?

Aug 18, 2010

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?)

c: inetpubwwwroot
edirect.aspx (set as default document in IIS and simple executes Response.redirect("sites/mercury/default.aspx")
c:documents and settingsall usersdocumentswebsitesmercurydefault.aspx (home page for the site & server)web.config includes

Redirecting To Page If User Is Not Authenticated?

Mar 3, 2010

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"

Getting Authenticated User's Username On A Subdomain

Mar 21, 2011

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>

WCF / ASMX :: WCF Storing Authenticated User Information?

Jan 15, 2011

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.

Detect If User Is Authenticated With Active Directory?

May 21, 2010

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.

Security :: How To Control The Number Of Authenticated User

Dec 16, 2010

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.

Context.User.Identity.IsAuthenticated Always Authenticated?

Mar 3, 2011

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="?"/>
