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?
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?

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 am working on a ASP.NET 2.0 application. It is hosted on IIS 6 on Windows 2003 server.
Few pages have jpeg images (around 50 images and 50 KB each). It takes long time to load the page for the first time. But when i open the same page for the second or third time it is faster.
why does a web page take long time to load for the first time?
Is it cached somewhere when it loads for the first time? Do we have any control over it?
The SQL below takes at least 7 second to run and may even time out.
There are a lot of records over a million in each of the two tables being inner joined and then being searched on.
I have tried putting an index on the create_date# and rdat# hoping that sql would not have to access all the records
But it seems to have made no difference, so I have now deleted those indexes.
I realise that manipulation of strings comes at a price but I can only work with the data I have been given.
Do you have any tips or trick that I can use to optimise this code?

View 1 RepliesIn development, our Asp.Net 4 website takes a fairly lengthy time to start after the project libraries are built
We do a fair amount of population of statics etc, but not enough to justify the length of time it takes the app to come up (probably 3-4 minutes)
We aren't building the website, just the libraries, and batch != true in the compilation element in the .config file.
I will try log some diagnostics, but any other pointers would be useful
Project
I'm running a single page (default.aspx) web site in Visual Studio 2010. I have a few other projects in the solution, but they're all taken out of the build queue at the moment. I'm using Visual Studio Development Server as the web server (I haven't tried IIS yet). I'm using the HTML5 Boilerplate from [URL] I'm testing in Chrome and IE8
Problem
Visual Studio 2010 is outputting "Debug" information to the Output window every time I refresh my browser. Whilst this isn't a problem in itself, it seems to be extremely slow in doing so... it takes around 4 seconds to show the page in full from initial refresh.
I've noticed that the "Script Documents" folder appears in my solution view, and some files (notably JS files) seem to take a while to show up. I've tried removing all the JS and CSS file references from my page, but it still does it.
So, to troubleshoot I've created an index.aspx page with no content apart from the generic ASP.Net template code, set this as the start page, but it still takes just as long to load up as the other page.
As a last resort, I've created a new project and tried it with no changes to the default page - still the same, takes a few seconds to finish loading in either browser.
The strange thing is that this happens even when I stop debugging in Visual Studio and browse directly to the URL on the ASP.NET Development server.

I am dynamically creating a table of checkboxes on my test.aspx page. The dimensions (row and column count) of the table are determined by querying the database. In test.aspx page, I do the following:
<script language="C#" runat="server">
protected void Page_Load ( object src, EventArgs e ) {
//Query the database to get the data for rows and columns
CheckBox[] chkBox = new CheckBox[rows * columns]; //creates a collection of checkboxes
//Iterate over the query set in a double for loop to create dynamic checkboxes
}
</script>
Right now I have the number of rows=20 and columns=10, but it can increase (with the columns more likely). I used the Net tab in Firebug to ascertain the time taken by different events and found that GetTest.aspx is taking close to 4 minutes, which is too long a time to wait. Is there a way to being down the page load time? Is my approach to create dynamic check boxes correct?
Whenever I stop debugging an ASP.NET IIS web application it seems to take very long before VS2010 becomes responsive again (2 or 3 minutes). This happens when I close Internet Explorer 9 (which stops the debugging session), stop debugging in VS (which closes the browser) or when I detach the debugger from the debugging menu (which leaves the browser open).
My CPU time for devenv.exe goes up to 25% during this period of time. I use the professional edition (no intellitrace). Starting without debugging performs ok when I close the browser. I have some add-ins and extensions installed like TestDriven.NET, Resharper, PowerCommands, Productivity Power Tools, VisualSVN,...
What should be the approach while designing when you know that your page would take considerable time to load? e.g. if it has controls which are heavy & some which are lighter? Can we make use of any of the design patterns to solve this issue?
