Security - Secure Way To Validate The User's Credentials Against AD?
Mar 1, 2010
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?

PrincipalContext.validatecredentials(username, password);
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 am building a web application that is limited to one database, thus I cannot use the handy ASP.NET config tool. I am attempting to use SqlClient to authenticate users from a user table I added to my database. Here is the code I have thus far:

In my application, I have users request accounts, and then an admin goes in to approve or reject the account. When the admin approves the account, the create user wizard is used. After the user is created, I set the new user's role, and update a few other items in my database for user tracking, and send out an email to notify the new user of their account status. Here's the kicker: Once this new user is created, the admin, is now logged in as the new user. How is this happening? And how do I stop it? Here is my CreatedUser code, scrubbed of non-pertinent code.

I'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 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?

I have an ASP.net 2.0 application on an IIS6 server with a second server running SQL.
The problem I have is that I can't use Integrated Windows Authentication to authenticate against the SQL server, instead the IIS passes its machine name (DOMAINMachineName$) to the SQL server. Of course I can add the necessary permissions to the machine name account on SQL, but I want to use the local user credentials in Integrated Windows Authentication to authenticate against SQL.
I have tried to find some reading/articles online but apart from a basic understanding I can't find the details I need to implement into my application. All I have found is that IIS doesn't pass the credentials onto a remote machine when using Integrated Windows Authentication, and Kerberos should be used instead. I have no experience of Kerberos or how to use it in ASP.net so I am hoping it can be done using Integrated Windows Authentication or be pointed to some good easy to understand articles on using/implementing Kerberos.

I'm running an ASP page that is using a WCF client to get some data. How can I set/pass the Network Credentials (of the user that performed the request, not the .net pool thread) on the WCF client so the WCF service will be able to perform impersonation using these credentials ?

I have created an asp.net site with anonymous access turned off. Its for an internal (intranet) system which uses User.Identity.Name.ToString() to get the users login windows ID and then displays some records from a datagrid depending on their login ID. Is this secure? Also i am struggling to workout how best to store the result of User.Identity.Name.ToString() as I am not keen on storing it in a hidden text field and would rather not call it all the time unless this is the best way?

I have a custom mini login user control that I have embedded in the top of my website which shows on every page. These pages are non-secure HTTP://. I would like to avoid having to redirect the user to a HTTPS page to perform the login but I definitely don't want to send login credentials to the server in plain text.
I am trying find a method to send the user's login credentials encrypted via https from a non-secure (http) page.
I tried to set the postbackurl for the login button to itself but in https, but the user's input is not retained and the buttonLogin_click is not fired when I set the button postbackurl property. My ASP.net web application is VB.Net framework 4.0
I am assuming this can be done because I see lots of websites where login fields are on available on every page and they are running http and I can believe they are not encrypting the login credentials.

We have an IIS/ASP web page from a vendor that we have just dropped onto a webserver within our company. The ASP pages do not come with any sort of authentication built in, so I am trying to configure the site to prompt for credentials before being accessible. I would like the site to prompt for the credentials in all cases (ie. I don't want Internet Explorer to pass through the credentials of the logged in user). I want authorization to this site to be allowed only to members of a certain security group with Active Directory.
Is there a way to do this? I'm not really an IIS guy, nor an ASP developer, so I'm kind of feeling my way through the dark here.
Based on some searching, I have tried adding the following to the web.config file:
[Code]....
I have also installed the IIS URL authorization role service, and have tried playing around with the authentication settings within IIS, to no avail.
I am using IIS7 on Server 2008.
