I have just installed SQL Server 2005. I selected windows mode authentication. I am not able to login in management studion. Now, I want to use mixed and server authentication option inplace of windows authentication. so, would that be possible after installation.
View 2 RepliesI had a problem login management studio (Sql server 2005) using windows authentication because it doesn't show me any server name to connect and if I put my computer name and user name (my-PCpatel) login was failed.
So, I decided to uninstall it and install it again using mixed mode authentication. After installation I select sql server authentication instead of windows authentication and put login name as "sa" and password that I had put it during installation. But the connect button is dark gray(the way I can not select it or press it on) while the other button (cancel, help, option) can be selected or pressed.So, why am i not able select or click on connect button?
Mixed Authentication Using IIS 7 On Windows Server 2008?
View 2 RepliesJust to describe the scenario. I have a website. This lives on a webserver. On that webserver is an SQL server. The website connects to this database using windows authentication. I have written a windows form application that connects to the SQL Server on the webserver. This application is being run from a location on out intranet. The Winform application use SQL authentication to connect to the database. The SQL Server didn't have mix mode authentication enabled. So I enabled it. The winform application could now connect to the SQL Server.
This is where it starts getting a little strange.
The Website that was already connecting find using integrated authentication starts failing with:
Login failed for user 'NT AUTHORITYNETWORK SERVICE'
When you are enabling mixed mode authentication, you are adding another authentication method, why would the original Windows authentication fail?
im using windows 7 home premium-64 bit,when i want to install sql server its not asking for mixed mode its directly creating windows authentication mode but i want to use sql server authentication mode,when im installing im unable to see any mode selection?
View 4 Repliesi have installed sql server express using windows authentication mode,but i have a doubt if we want to acces the data from front end we type like uid="",pwd="",servername="" but when using windows auth what credentials we have to give or there is no need of any details?

View 3 RepliesI set authentication mode to Windows in the web.config and I enable Windows Authentication and disable the Anonymous Authentication in IIS 7 on win 7, but HttpContext.Current.User is always null.It works fine when I host the web app in IIS 6.0.
View 1 RepliesWhat do I need to do in order to change an application from Forms Authentication to windows authentication?
View 2 RepliesI have a web application (intranet based) which uses Windows Authentication. Unfortunately there are public computers that have public logins at some company locations. My web app doesn't support these public logins because I need to know the user workingSo, even though these public users are windows authentication users, my app will fail because I have no user account setup for that particular account. I want to then try Active Directory Authentication.In my Default.aspx.cs I'd have something like this
protected void Page_Load(object sender, EventArgs e)
{try
userContext = new UserContext(); // If the authenticated user isn't a user in my system then throw an exception
}

How do you back-door authenticate Windows users into a website using forms authentication running on IIS 7.0?
View 1 RepliesI've been asked to convert an asp.net application from forms authentication with roles using the aspnetdb database to use windows authentication instead.
what is required to do this? can I still use the roles defined in the app and stored in aspnetdb?
I have an (ASP.NET 3.5) intranet application which has been designed to use forms authentication (along with the default aspnet membership system). I also store additional information about users in another table which shares its primary key with the aspnet_users table.
For users who are part of our domain I store their domain account name in the secondary users table, and I want to automatically log in users whose domain account name matches a name stored in the table.
I have read the guides which are available - they're all from two years ago or more and assume that you are able to activate Windows Authentication on a separate login page that allows you to extract the domain account name. From what I can tell, though, this is not possible in IIS7 (the overall authentication method is applied on all pages and cannot be selectively deactivated, and both authentication methods can't be applied on the same page).
Is there a way of getting IIS to pass through the windows domain account name of the requesting user? I don't need proper AD authentication, just the domain name.
Is it possible to disable windows authentication on one or more subfolders of an ASP.net application using windows authentication?
For example:
A website contains several other folders that contain parts of the overall application: /frontend,/backend, /login
The bin folder is on the same level as these subfolder, i.e. the root of the website.
All of these subfolders contain pages that use binaries that reside in the bin folder of the root of the website.
The user must input windows credentials when visiting a page in the backend folder, but not when visiting a page in the login or frontend folder.
I have a question about mixed mode authentication. I've been doing some research into this, but I haven't found the answer yet, so I figured I'd just ask:
I have an internal application that requires login. Right now it's using forms-based authentication. We'd like to make it so that, if you're internal and authenticated against Active Directory, you don't need to login to the application. However, if you're coming in from the outside (or don't have an AD account), it would then require them to login via the forms-based Login.aspx page.
From my research, it seems that the only way to do this is to enable forms based auth as the default membership provider, then on the back-end do a check at Page_Load to pull their login name, match it against the .NET membership and then authenticate them automatically - am I wrong on this?
The documents I've found all seem to point to the user having to login anyway, just the login being stored in AD - instead of having the user just login once to their machine in the morning and using that to verify them and their roles in subsequent applications.
I have the requirement for internal users to acces our web app without loggin in manually so using windows authentication, external users need to be refered to a form based authentication.
Now I have implemented the solution [URL] ....
However I also need to employ roles for authorization. The forms side is all set up but I cannot seem to get it to work for the windows side of things, looking for implementing a mixed mode involving roles?
I tried adding in an extra provider
<providers>
<add name="SqlRoleManager" type="System.Web.Security.SqlRoleProvider" connectionStringName="aspnetdbConnection_dev" applicationName="Corp.Web.GSP"/>
but how to configure it for usse only by the windows users. Secondly if I set it as the default where I have code like
if (Roles.IsUserInRole("Internal") || Roles.IsUserInRole("SysAdmin") || Roles.IsUserInRole("Sales"))
{
I get an
Method is only supported if the user name parameter matches the user name in the current Windows Identity error
<add name="WindowsRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" />
I am getting this error when trying to connect a database from another computer in my home network:
System.Data.SqlClient.SqlException : Login failed. The login is from an untrusted domain and cannot be used with Windows authentication.
this database is using windows authentication. sqlserver 2008.
What is the connectionstring that I need to use in order to get the database?
I'm having a tough time implementing mixed-mode authentication (windows & forms based) for my application using IIS 7. Doing it in IIS6 is easy, but the process doesn't translate to 7/7.5 - and my research has led to me to conflicting answers, none of which.
I have redirect page called WindowsLogin.aspx, and a forms-based one called Login.aspx. I'm having difficulty enabling Windows authentication for just WindowsLogin.aspx.
I am trying to implement single sign on for users within our domain and if the are not then they get re-directed to the login screen to use forms authentication.
I have followed this tutorial below
however I get two issues firstly if I go to my forms authentication page no css or images now display and if i try to login i get an error.
If I go to the login page which should recognise me from the AD I get 401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied.

I created a mixed mode authentication mechanism based on a few of the articles that I have read on this topic. It's similar to something like this: [URL]
Basically, there are two web applications. One accepts the Windows Auth and one accepts Forms Auth. The Windows Auth then creates a forms auth ticket and passes control to the Forms auth application. This solution works fine when both applications are housed within the same IIS web site.
Now, order to control the security of this solution we set up multiple IIS web sites on the same machine. Web Site 1 serves external traffic (forms auth) and Web Site 2 serves internal traffic (windows auth).
So the design is that an internal user can hit the site using Windows auth via a internal name (myserver) while the external users use Forms Auth hitting [URL].
All that said, the solution works when the two applications are in the same site. Doesn't work when they are in different sites.
I have a web application set up on our intranet that uses windows authentication (successfully) that I am trying to link to a database running on a separate server.
The problem that I am having however, is that when I try to use a trusted connection to log in to the sql server, instead of passing the domain/username of the person using the website the application is passing NT AUTHORITYANONYMOUS LOGON.
I checked that the authentication was working by having the website display a greeting that does identify my username correctly when I log on to the site, so it isn't an anonymous access issue. I think it is an impersonation issue somehow despite the fact that set in the web.config file for the application.
Curiously, the web application works fine when I run it on either my dev machine or even locally through remote desktop on the production server. I'm not sure what's going on here.
Finally, I'm running iis 7.5, windows server 2008 r2 and sql server 2008
my user will use form authentication against Active Directory or database. Theres no Windows Integrated Authentication there!!
What i want is when the user submit the authentication form, it will try to validate the user against Active Directory and if it fail, try with the database.
How can i do that? What i had in mind was to build a custom membership provider that will encapsulate the logic but im not sure how to start.
to connect the MS Sql server 2008 using windows authentication in ASP.Net 4.0 without change IIS user (ASPNet) permission.
View 1 RepliesThis is a real quick question, is it possible to allow Windows Authentication for an ASP.Net intranet site (on a test server) to authenticate against the production server user accounts? If so, how would I go about doing so.
