Web Service And Membership - Get UserID Of User When Not Logged In

Jul 21, 2011

I am creating a few web services for use with a mobile application. My current site uses asp .net membership and one of the web services will validate username and password.

In the web service I get passed uname and pword and just use

If Membership.ValidateUser(username, password) = True Then
Return "True"
Return "false"
End If

Is there a similar way to get the userid without logging the user on or do I need to create a Stored procedure?

I'm using membership and roles in a Silverlight Business Application. There is a RegistrationOperation_Completed event in the RegistrationForm.xaml.cs code behind file with:

else if (operation.Value==CreateUserStatus.Success)
this.registrationData.CurrentOperation=WebContext.Current.Authentication.Login(, . . .);
. . .

where I would like to obtain the UserId that was created for the newly registered user so that I can use it as the key to populate a userdetail table. How do I get it? All I have is the UserName that was used to register the new user.

WebContext.Current.User does not appear to return the UserId.

Security :: Running Application Under The Security Context Of The Logged In User (LDAP Authentication)

Mar 17, 2011

We are using membership provider for LDAP authentication. It is working as it should.

But what all configuration settings I have to do so that
all the future requests to this application run under the security context of the Logged in user account not through the some default user set in IIS.

We need to have this working because all the permissions on the database are based on the logged in user.

We are using form authentication for LDAP authentication. And having impersonation = true in web.config.

Web Forms :: Make "UserId" Equal To The "logged-in User" In Vb Code Behind

Aug 25, 2010

I need to insert a declaration in the codebehind function below that will make the variable "UserId" equal to the "logged-in user". In what way do I need to change the code below (elsewhere in the project, I successfully make reference to basically the same code and make the UserId equal to logged-in user by using this handler expression inside an image control: ImageUrl ='<%# Eval("UserId","Image.aspx?UserId={0}")%>'...But in the case below, the function is not fired by this expression, but rather by CustomValidator).

Sub ValidateImage(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)
If Request.QueryString("UserId") IsNot Nothing Then
' Get the connection string from Web.config.
Using conn As New SqlConnection(ConfigurationManager.ConnectionStrings("MyDatabaseConnectionString").ToString())
' Create a command object.
Dim cmd As New SqlCommand()
' Assign the connection to the command.
cmd.Connection = conn
' Appendy the parameter to the SqlCommand and set value.
cmd.Parameters.Add("@UserId", SqlDbType.UniqueIdentifier).Value = Guid.Parse(Request.QueryString("UserId"))
' Set the command text
' SQL statement or the name of the stored procedure.
cmd.CommandText = "SELECT Avatar FROM aspnet_Membership WHERE UserId = @UserId AND Avatar IS NOT NULL"
' Set the command type
' CommandType.Text for ordinary SQL statements;
' CommandType.StoredProcedure for stored procedures.
cmd.CommandType = CommandType.Text
' Open the connection.
' Convert the returned result to a bytes array.
Dim bytes As Byte() = DirectCast(cmd.ExecuteScalar(), Byte())
If bytes IsNot Nothing Then
' Set the HTTP MIME type of the output stream.
Response.ContentType = "image/jpeg"
' Write a string of Binary characters to the HTTP
' output stream.
' Send all currently buffered output to the client.
args.IsValid = False
End If

Security :: Access Denied For Logged User (anonymous User Is Fine)

Jan 7, 2011

I deployed a website where a logged user or an anonymous user can select data and download a XML file. The website generate the XML file in the server and then deliver it.

It works fine in my development environment, but after deployment, the anonymous user can download the file, but the logged user receive this error:

System.UnauthorizedAccessException: Access to the path 'd:HostsLocalUserheringerwebsiteUpload20110107094051.xml' is denied.

It is weird that as anonymous i can do it.

The website server help states this:

"Grant write, modify, delete access rights on website's folder

Your website executes under unique user account that by default has full control over the website's folder.
So your application can create, open, read, write and delete files and folders inside of your root folder.

There is no need and no way to change this permissions.

If, when running ASP.Net application, you still unable to create file or update it, you have to check your Web.Config file for "<Identity impersonate..." tag and remove it.

The only exception is when the application tries to modify a file or folder in "Application_Start" event of Global.asax file. This is by design that user authenticated only after the Application_Start even. Before the user is authenticated your website runs under an identity of Application Pool which is "Network services". That account doesn't have access to the folder of your website.

To make it work you eather have to move the code that tries to modify files or folders out of the "Application_Start" event of the Global.asax file or inside the event you'll need to impersonate your user by code."

But i am not using impersonate and the tag is not in my web.config.

How To Get Current Logged In UserID In Aspnet Mvc Membership

May 7, 2010

i am trying to show a list of users of my application "school", when admin logs in then he can view all the users in list but when school principals logins, he should get only users of his school, So i thought to get the current loggedIn userId first and then by that userId i'll get schoolId since userId is foreign key in school table...once i'll get the schoolId i can show the members of that school.

But my problem is how to get the UserID of currently loggedIn. I'm using MVC 1.0 Asp.Net -- "Membership" if my logic above is wrong then tell me the alternate good idea, so that principal can see only his users list.

Security :: User Being Logged Out Straight Away?

Jun 9, 2010

I have been creating a website using the SQLMembershipProvider. I have been using an administration account to create the back-end system for generating the users fine for about 2 weeks. I now have more users created and I can log in fine. However, when I log in as the newly created users, they can get to the page they are after, but if they refresh the page or redirect to another page, they get redirected to the login page. I have checked permissions, iis recycler, session state and security setting in my web.config (posted below) but nothing has fixed it. It cannot be IIS because it does it on my development machine as well as on the actual webserver and it works fine for the admin user.

Security :: How Does Each Page Get The User That Is Logged In

May 21, 2010

I've successfully made a custom membership provider that connects, queries, and updates my custom Oracle database. I found a good sample on MSDN. I also found documentatio on the provider itself. However, I cannot find anywhere example calls you have to make for the different actions within the web pages themselves. Where can I find that?

For example

How do I check if a user is already logged in? What do I do when a user hits the login button? How does each page get the user that is logged in? etc.I am not using the asp login control. I have custom form, custom data, and custom graphics.
