Security :: Form Authentication In A Web Service?
Dec 4, 2010
I want to create a web service that can authenticate user from my application. I will be sending user name and password from my app to the web service and that will deny or accept the user. I want to use form authentication using sql server. that this web service can be used by other team in my office so that they can just call the web service and the user will be authenticated.
Also, is it possible to use both form and windows authentication in my web service and authenticate the user both ways.

I am writing two ASP.NET apps. One is a web service that provides xml data and the other is a web client that will use the service to display and manipulate data. I would like for the web service to do the membership authentication and authorization. Is there any way to simply point the login controls in my client application to the web service instead of to a database. I assume I would have to provide the necesarry methods in my web service interface, which would then use the membership provider database I created and pass the results back through to the client.
Is this possible? I have seen many articles on security provisioin from a web service but none has really been what I am looking for. I was hoping that, since my service and my client are both written in ASP.NET, there might be some built functionality that would benefit me.

I have to invoke SSIS packages from web service in the most secure way. I think that windows authentication will be secure but i am not sure. I do not have much knowledge about how to achieve this and the information on the internet is very distributed.

I have set up the Auto complete control and the web service to populate it, this web service resides within the project that uses it, it works fine on my machine (if I had a nickel for every time I heard that from a developer...) , but when I install it on Dev, the site asks for authentication, then when I select the tab with the textbox that has the Auto Complete control, it asks me for authentication again. If I remove the Auto Complete control, it no longer asks me. The funny thing is, I can enter authentication info OR just click cancel and the web service works fine.
In the IIS site on Dev and in the Web config, I have turned off authentication (in IIS I use anonymous and in the Web.config, I set it to "none") My development machine is in a domain, for some reason beyond my control, both Dev and Prod are not in a domain; both Dev and Prod machines are Server 2008. how to prevent this authentication form from showing???

I have created a WCF service that will serve as authentication service for Silverlight client.The problem is that when I make a call to FormsAuthentication.SetAuthCookie in the Login method below, I get a null reference exception.

I am looking for a code which does authentication using service account username and password. I mean username and password which has permission to access the active directory and then authenticate the actual username and password provided by end-user. Googled everywhere but could not find any suitable code.

I'm trying to use ASP.NET WCF Authentication Service from a Winforms Application.
I am referring to this article as a tutorial.
for silverlight clients, the WCF Auth service works well.
but for Winforms Apps,
[Code]....the AuthenticationServiceClient.IsLoggedIn() always returns false even after login.
what is the cause of this and is there another approach I should take when I leverage ASP.NET authentication from Winforms?

I have a question regarding Form Authentication Session Timeout
I have a form authentication and i have set the session timeout in my webconfig.
After I login to website using my form authentication, the session is not timing out even after i login more than 30 minutes.
It seems i'm still authenticated and can access everything.
Is it normal ? I thought if we set the timeout in webconfig it will automatically log you out because the session expire.
<authentication mode="Forms">
<forms name=".authentication" loginUrl="Login.aspx" defaultUrl="Default.aspx" protection="All" timeout="30" path="/" requireSSL="false" slidingExpiration="true" enableCrossAppRedirects="true" domain="" />
</authentication>

I want to use directly form authentication by editing the web.config like this:
<authentication mode="Forms">
<forms loginUrl="Authenticate.aspx" protection="All">
</forms>
</authentication>
<authorization>
<deny users="*"/>
<allow users="abc"/>
</authorization>
Then I add a Login control in Authenticate.aspx, after click Login button there is an error like this:
An error occurred during the execution of the SQL file 'InstallCommon.sql'. The SQL error number is 1802 and the SqlException message is: CREATE DATABASE failed. Some file names listed could not be created. Check related errors.Is there anyone know what the problem that Form authentication cannot directly apply to Dynamic Data site as usual?

I'm doing form authentication with roles to access areas of a website. The authentication is working great, but I'm having trouble with the roles piece. On the page in question (needing to narrow the access), the top lblGrps.text (below) shows I'm in the group I need to be in, while the response.write (also immediately below) reads false for the EdIT group:

I am developing a website in which I am using ASP.NET Form Authentication and everything is working fine as I am expecting. I can authenticate user from login form, I can read user roles from database and can add authenticate ticket in which user roles are stored as user data etc. etc.
Now I want to give user a page where user can update his roles in the database by selecting any role he/she want from the list of checkboxes. I know how to update the user roles in database but I want to know how to update user roles in the authentication cookie after database update.
Let's say in the start user is in "Seller" and "Buyer" role and later he want to become member of "Agent" role as well and he update his roles from the given page and everything is updated in database. Now according to database user is member of three roles but User.IsInRole("Agent") method is returning me false because the new role "Agent" is not updating in the authentication cookie.
How can I update a newly added role in authentication cookie when user is still logged in.

I have created an Intranet site using windows authentication based on role membership. It is working great. My Web.config is shown below.
<authentication mode="Windows" />
<roleManager enabled="true" defaultProvider="AspNetWindowsTokenRoleProvider" />
<authorization>
<allow roles="D820Developers, D820IT, D820Staff, D820Providers, D820Supervisors, D820Directors, D820Interns" />
<deny users="?"/>
</authorization>
Now my user wants the capability of being able to login to the intranet site as another user. For example, IT guy needs to login on a user's system to set some data.
I have created a standard MS Login Page. However when I try to login on the page I get the message
Your login attempt was not successful. Please try again
I do not have a database (aspnetdb.mdf) storing user information but login against the active directory. Can you use the login form with windows authentication without a database?
