Security :: Membership.validateuser Always Returns False While Migrating Vs2008 To Vs2010
Nov 12, 2010
We have just migrated our application from VS 2008 to VS 2010 and our database from Sql server 2005 to 2008. Everything was working great until i tried to login to the site.
As when i try to log into the site, i am surprisingly always getting "FALSE" from Membership.Validateuser (). I goggled it and now i know i am not the alone victim of this irritating bug. Our live site is going to be down...

I know this looks similar to other questions here but I don't think my case is the same as theirs.
I have a website that uses the AspNetSqlMembershipProvider to validate users. I would like to use the same database from a console application. According to several articles on the web I can use the System.Web.Security.Membership class from outside ASP.NET by copying the appropriate sections from web.config to app.config. That is what I did.
My console appliction can get the user with the requested name and I can confirm that the user is approved and is not locked out but ValidateUser returns false for a correct username and password pair.
I have found articles where people have had trouble with migrating code which may be due to a machine key mismatch but have also found a reference saying that machine key is only used if the passwordFormat property equals encrypted whereas I am using hashed.
Is the issue that the two pieces of code - the website and the console app - are in different assemblies and the assembly name or other property is being used during password hashing? In both cases the application name property is set to /.
Should I continue with this approach or just access the database directly and hash the password myself?

I have an old website running fine in Classic ASP with large customer base registered onto the site. The current site allows users to have their own user name(unique) registered against an ID assigned to them. They can change the User name later as well provided it is still Unique in the database(Database is SQLServer2005).
The Problem: Now i want to move the website to .NET and want to use the .NET Membership. I know how to create the database structure in SQL Server through aspnet_regsql script but my problem is how should i import the existing username and passwords as the password stored in MembershipDB is Hashed (salt). Also i might want to allow admins to impersonate as users later.

I have an existing ASPNET role/membership database created on SQLExpress 2005 (WIndows 2003 Server). I created it under the .NET 3 framework many years ago using the aspnet_regsql.exe application in full GUI mode.
I am setting up a new Windows 2008R2 server with .Net Framework 4 and SQL Server 2008R2. I don't want users to have to recreate accounts or create roles, etc.
So...
1. Should I backup the current database and import it into the new system, and if so do I even need to use the aspnet_regsql.exe application. (If so which version do I use, different aspnet_regsql.exe files exist in different directories (i.e., FrameWork, FrameWork64)
2. Should I just run aspnet_regsql.exe on its own and then somehow try to import the current data into those tables.
I am concerned that if I just import somehow the roles within SQL server will not be created properly.

Our web application hosted from windows 2003 server, is trying to access a file present in a shared folder of another windows 2003 server. The path for the shared folder is configured in the webconfig file in the below format.
<add key="ReportPath" value="\<Server_Name>Reports"/>
if (!File.Exists(ReportPath))
/ Show the report in a link
This function File.Exists() always returns false and when I try to remove the check, it returned the exception, "Logon failure: unknown username or bad password."

WARNING - Absolute beginner here with VS. I'm expecting a steep learning curve, but I'm up to it! I'm trying to create a website with membership/login. Followed the above walkthrough MANY time, and been very careful with the username and password entered, but I keep getting the message that the loging failed. The asp application name is "Membership" This is the whole thing, automatically created following the walkthrough, apart from adding 2 members - yes, did go to the memberpages folder at the set rules page.
Solution Explorer:
Solution 'membership' (1 project)
- //localhost/membership/
- App_Data
- ASPNETDB.MDF
aspnetdb_lpg.LDF
- MemberPages
web.config
- Default.aspx

- Login.aspx
Login.aspx.vb
webconfig
aspnet_Membership: (2 members)
PasswordFormat = 1
The ApplicationId for the 2 members is different - should it be?..........

I have successfully created a SQL Server database that is holding the ASP.NET Membership data for my site. I have also created two textboxes and used them for user authentication after he/she keys in a user name and password. I would now like encrypt the password before comparing to the value stored in the Password field of the SQL Server database. However, I have been unable to do this so far.I have consulted the MSDN page for the embershipProvider.EncryptPassword method but I do not understand how to implement it. I have also tried searching Google for this method but I have only found a couple of examples and I don't understand those either.

I have a webservice project and a web project in the same solution.
The web project implements a membershipprovider.
I want to be able to authenticate user via the webservice project but when i call this method in the webproject:
public static bool AuthUser(string userName, string password)
{
return Membership.ValidateUser(userName, password);
}
I get this inner ex."Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed." Calling the method from the webproject works fine. I understand why I get the ex. but not how to solve it.. UPDATE Well I fixed the issue by deleting the C:UsersJRBAppDataLocalMicrosoftMicrosoft SQL Server DataSQLEXPRESS folder.. However now the method always returns false.. It almost seems like it doesn't use the proper connectionstring.

I had been trying to solve this but there is a hidden key i wish someone point me to.
I had a simple membership database with users in first the Membership Provider configured for clear password to retrieve the original password .
Now a new requirement say that the password must be hashed and reset .
I configure the Membership password to hash , and Implemented the Reset Password Module.
My problem is as follow.
If the user is new registered user with the new configuration the password and the security answer is hashed.
also when I go and reset the password it continue to be hashed.
Now I thought that with new configuration if any previous user with clear text configuration , If he use the password Reset module , because my configuration now is hashed , I expected that the new password and security answer will be hashed . what happen is old user continue in clear text even if the configuration is hashed. so If I had new users everything is fine.
old users Membership Provider somehow know they had been stored in clear text and it keep change password and security answer in clear text . If I delete this user and create it , Membership Provider understand that everything will be hashed. I need to know how it know this , I need to migrate users not to delete and recreate users .
Also if there are no solution for that , I wish Microsoft Consider it in future cause it is a real user scenario, that can happen imagine a business system that related to membership user Id , deleting users and recreate them is not a solution .

im itrying to debug javascript using vs2010
but i can't set breakpoints?
how can i do this?
edit:
i just noticed something, every time i try to call a function, no matter what function, in javascript, somehow jquery and ms ajax framework javascript captures it and checks if the document is ready (document.onready or other) and never returns the control back to the function im calling! why on earth is it doing this? i've never asked for it to!
all i have is references to these libraries, script/link references as you do on the top of your master page.

We have had a web application built in vs2008. We have recently set up vs2010, and when we build the solution we are getting this error.
The CodeDom provider type "Microsoft.VJSharp.VJSharpCodeProvider, VJSharpCodeProvider, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" could not be located.
We have tried placing the following in web.config
<compiler language="vj#;vjs;vjsharp" extension=".jsl;.java" type="Microsoft.VJSharp.VJSharpCodeProvider, VJSharpCodeProvider, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">

I have been working on this project for a few months in VS2008.. now that we are getting closer to the end, one of the other programmers has been working and doing his in VS2010, so when i try to open his projects in VS2008 it just shows up as XML.. so i have to open in VS2010.. thats fine..
But if i try to open my project in 2010, it prompts to use the conversion wizard.. Should i be concerned or are there any issues with doing the conversion? Being the end of the project, i dont want to cause issues at this point.. So would like to know if converting the project file at this stage in our project a good idea? Will there be any issues using his code with mine since they were developed in 2 different versions..

I have an application with a custom mebership (I'm still working on it). There is some funcionality in the application for asociating users. This means that (if already associated) one user could switch to some other user with just a click.
My question is:
Can I do a function that would allow me to authenticate one user without sending the password as a parameter?

For that, I made my own users and passwords tables and hashed the passwords myself. Now, I would much rather move to Microsoft's built in membership provider with asp.net in sql server. Does anybody know a good way to migrate over?
The only real idea I've had so far is to make both systems run simultaneously, then when a user logs in, validate them in my old system, then ask them to re-enter their password and save their new stuff in the microsoft's system... then clear the record out of my old system. Eventually, I would hope that would move everybody into the new system. But that seems annoying and messy. Is there some better way?

I've got a system that was partially written by someone else and is a complete maintenance nightmare for such a small app. I've finally been given changes which justifies just rewriting the horrible mess so I am moving it to Django.
Before I take the plunge, I've been trying to move over the password hash and salt into the Django auth tables [sha1]$[salt]$[hash] but can't get it to hash properly (resetting passwords isn't really an option).
Here is what I've been able to find out so far:
ASP.NET stores the hash as base64 string and uses a base64 salt (before hash) I can obviously reverse the base64 hash to a byte array Django uses a hexdigest, I tried BitConverter.ToString but they hash differently

I've an EntityCollection< T > which contains an element but the Contains method returns false.
I've overriden T's 'Equals' method but the 'Contains' method does not call it (while it's said so in documentation).
When I do foreach (T x in coll), x.Equals(element) returns true.
code:
contains(object entCol, object val)
{
var coll = (ICollection<GraphicSockets>)entCol;
var socket = val as GraphicSockets;
foreach (GraphicSockets sock in coll)
socket.Equals(sock); //true for first element, GraphicSocket's Equals function called
coll.Contains(socket);//false, Equals function not called}
the code i'd actually like to use is
private static bool contains(object entCol, object val)
{
Type entColType = typeof(EntityCollection<>).MakeGenericType(val.GetType());
MethodInfo contains = entColType.GetMethod("Contains");
return (bool)contains.Invoke(entCol, new object[] { val });
}
this worked once but stopped when i started using wcf, i wonder how this contains method works.....

I'm using a model which receives some input from a form and has some validation logic attached via attributes. In one case I'm validating personal names, which should include only letters, apostrophes, spaces and dashes, and be no more than 50 chars long. So I have a model property like:
[Code]....
Everything works fine BUT the RegularExpression attribute: if I add it, I always get a validation error, even when what I type in my form is a valid name (e.g. "Foo"). No matter how I modify the regular expression or what I type, I always get an invalid name error.
(For some reason, I cannot see the regex posted correctly here: it is just ^ followed by the Unicode Letter class and []+ including a Unicode letter class, apostrophe, whitespace and dash, ended by dollar: i.e. start of string - any letter - any of the following: letter, apostrophe, whitespace, dash, 1 or more times; end of string).
What I'm doing wrong here?

I have a ListView control and under ItemTemplate I have following code:
Code:
<asp:Label ID="Label1" runat="server" Text='<% #MatchCategory(dtCategories.Rows[i]["ID"].ToString().Trim(), Eval("CategoryID").ToString()) %>'></asp:Label>
The MatchCategory method just checks if two values are equal and return true or false. Just below this code I am separately printing dtCategories.Rows[i]["ID"].ToString().Trim() and Eval("CategoryID")
acan see matching values but MatchCategory method always returns false.
