View 3 RepliesI have an intranet web application, where i have windows authentication = true in web.config. I hear from end users that the website is aksing for their login credentials and they don't like it. By the way i am getting theusername from HttpContext.Current.User.Identity.Name and Domain Name from Mid(UserNameID, 1, InStr(UserNameID, "") - 1).In IIS, anonymous access is unchecked and Integrated wnidows authentication is selected.

In my environment, we use Active Directory as our password repository. I'm writing an app that uses the users windows session (windows auth) to authenticate the user. This is working well, but I need to provide a way for users to log in as a different user. I setup a web form to accept a username and password. My question is this, I need a secure way to validate the user's credentials against AD. I cant have the credentials passed as clear text. Ive come across the impersonate user functions, but i'm leary because you have to pass a clear text password into the password field. I know I could also use LDAP, but without a certificate, I know plain LDAP is relatively insecure. Can someone point me in the right direction of a more secure solution to query AD with the credentials?

Takes more time and high cpu usage to validate.
Is there any alternative way to validate credentials or any way to reduce the load and time?
i have a problem with forms authentication. i have a website and want to restrict access to an especific folder. i want the access to this folder be made via the login form this is what i have in the web.config
<authentication mode="Forms">
<forms name="Compra" loginUrl="wfLogin.aspx" path="/" protection="All" timeout="30" />
</authentication>
<authorization>
<allow users="*"/>
</authorization>
Then this to restrict folder
<location path="Admin">
<system.web>
<authorization>
<deny users="*"/>
</authorization>
</system.web>
</location>
the problem is that when the user login with valid information the website return to the login form.
I have to post my request to the web page [URL] and this require 3 credentials namely account id ,username and password and i have to pass the some data for the fields in the page
View 3 RepliesI have a site where users can register an account. To do this they have to enter various details about themselves (Name, DOB, Email Address, Password, Username etc..).
However, I would like them to just have to enter their Facebook username/password, and have all this information pulled from their Facebook user account.
How is this possible using ASP.NET 2.0?
I have a mvc2-website with windows authentication.
<authentication mode="Windows" />

In IE the website keeps asking several times for my credentials per webpage. In Firefox it works correctly.
I have a zealous network administrator who insists that we must use https on an intranet web application in order to safeguard user's credentials. The app is an asp.net web app that uses Windows Authentication to automatically identify users and log them in. There is no login dialog and user's never enter their login or password. The application does not process any confidential data, and the only rationale for requiring https is to "safeguard" users credentials. Additionally he stated that ntlm can be easily hacked.I responded with some information from an MS white paper on Windows Authentication that said it was the recommended way of authenticating users, and that user's credentials were safe because their passwords are not transmitted across the network when the application authenticates them since it sends a hash of the password.

View 4 RepliesI am the web developer at a medical clinic. I have 2 scenarios going on:
First, I have a physicians only component of our employee portal to allow access to only physician shareholders or physician non-shareholders. My structure is built like:
Physicians Only
Administration
Affiliations
Calendars
Compensation
Minutes
The Affiliations folder is only going to be accessible by the physician shareholders. Therefore, I have security roles set for Physicians Only and Affiliations. When I test, the security is set correctly on the folders. However, when I try to login as different people, all with different roles, I have to login with user name and password, twice, before the system allows me in.
Secondly, I have secured areas within the employee portal also. However, when I navigate to them, the system doens't usually prompts me to login. If it does prompt me to login, it too, is on the second try. So how does it know who I am? And more importantly, how do I get the system to actually prompt the user to login with their credentials?
Is the above possible? Basically i need it as I am creating a site where users can upload files to a shared network drive which is secure and has a system account
When a user clicks on upload file, If possible I would like the page to automatically kind of log in with the system account, copy the files and then log off. I know I could achieve something similar mapping a drive but would prefer not to do that for these reasons;
- Security risk if the mapped drive for some reason isnt removed by the code
- User may not have the drive letter free.
I'm trying to write a simple login page, that will allow my users to login to my site using their Active Directory credentials (using their username / password we give them through AD).
I want to do 2 things with the login:
1. I want to check the username / password against our AD and verify the person is a valid user within the directory.
2. I also want to store the entry within a global variable so when the user fills out one of the forms within the site it can Insert the data into a SQL table i have running.
** we are using this site to do Setup Change Request Forms / Termination forms etc. and I just want to verify the person signing off on the form is the person logged into the machine -- use it as an "electronic signature per say".
I'm using a vb.net 2.0 approach - as i only have access to visual studio 2005 and i'm more of a vb programmer then a c#.
If anyone has any examples or can walk me through how to go about writing out this page that would be great.

Unauthorized: Access is denied due to invalid credentials.
I've been researching and I've spent pratically all day on this. Here's my issue. The website uses forms authentication that we authenticate against active directory. I've been attempting to access files we have on a network share and push them down to the user (when they request them) in an http response. I keep getting "Access to the path <unc path> is denied".
Here's the code:
[Code]....
Things I've tried:1) When I add the "Computer" to the permissions of the folder it works and I dont even need to emulate a user (essentially just commenting out this code), but I'm not sure we want to explicitly give the computer access to some of our network shares 2) I've verified it's the correct username and password for the active directory account and that they have permissions on these network shares 3) I've fooled around with the WebProxy class with no luck (as I'm not entirely familiar with it) 4) I've tried impersonating the user by creating a windows token and passing the token as credentials (i've done this with similar websites) with no luck, plus this seemed a bit complicated for something I figured would be relatively easy.Its almost as if, the WebClient class isn't even using the credentials i've passed it.We've got it working now, but only by giving the "Computer" specific permissions on the network shares, which we'd like to avoid.
This could be very straight forward for some of you, but I got caught up. I am doing very simple test - browsing from IIS Manager to see the default page or "under Construction", however I am being challenged to provide my login credential . When I provide my login credential, I am able to see the default page. I wanted to see the default page without providing my credential since Enable anoymous access + basic authentication I am simply wanted to see the default page asit is working on other servers except this one. I have included screen print to make sure may question is clear.
View 3 RepliesI'm working on an ASP.NET project for the first time in about three years; in the meantime I've been working with Python/Django, PHP and Obj-C. Anyways, picked it right back up... except something that is totally killing me right now, and I have a feeling it must be staring me in the face:
I'm trying to bind to an LDAP server, for the purpose of authenticating users. The way it works here is, you bind on your own credentials, use that to find the Distinguished Name of the user you're authenticating, then you bind again on their DN and their password. If the bind is successful, the password was correct and the user can be authenticated.
Here's the problem - the first bind (on the fixed credentials, the ones with the ability to search for users and their subtrees) works fine. The search works fine. The second bind fails, no matter what, with the LDAP error INVALID_CREDENTIALS. This happens even when completely valid credentials are supplied.
Here's the code, with the usernames and passwords redacted, of course...

I was wondering what the following error means: Login Failed. The Login Is From An Untrusted Domain And Cannot Be Used With Windows Authentication. Initially, when my application was much simpler, I had no permissions and roles and my authentication mode was set to "windows". Afterwards, however, I added authorization, changed the authentication mode to "Forms" and ever since, when I try to login, I get the error above.
View 5 RepliesIs it possible to have multiple login pages for different folders within an asp.net application? Say I have this structure:
/admin
/customer
/login-admin.aspx
/login-customer.aspx
I have 2 different login forms. One for the admin people and one for the customers (the forms are different as the customers need to provide extra information on their login page).
In the authentication section of the webconfig file (which is at the root of the web app), I can only specify one Login page. So how can I make sure thaf if anyone tries to access a webpage in /admin they will be redirected to /login-admin.aspx and if they try to access a webpage in /customer they will be redirected to /login-customer.aspx ?
I'm writing a simple Intranet application using windows authentication. I want to restrict access to Safe/UCantSeeMe.aspx. I am aware of the AuthorizeAttribute, but this only works on methods. I also found a good post on doing this with the MVC pattern, but I'm not using MVC. This can be done with roles in forms based security. I read on MSDN that using windows based security means roles are based on groups, but it doesn't go into any detail. how can I restrict access to Safe/UCantSeeMe.aspx?

I want to create a website that a user can logon and view their data. They should also be able to logout. I'm wondering how to achieve this WITHOUT using the Membership provider api provided by Microsoft. This is what I think should happen.
1. user enters name and password and clicks button.
2.If username and password are correct the user is redirected to a webpage with their details.
3.A session is created.
4.The user logouts and the session is deleted.
