Security :: Validating User Password From Membership Provider Elsewhere?
Feb 9, 2011
I am using Membership provider.. I integrated the aspnet member tables into my database.
I need the user to enter password on a data entry form and validate it against the membership tables.
How can I do this. This is the set up. I have few fields and user enters those fields and also enters the password, and submits the form. It is kind of like signature... i am looking for something like..
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 .
I am using a custom membership provider with a custom ValidateUser method. The ValidateUser sends and additional parameter to authenticate my users (Username, Password, and Dealer). I created a custom stored procedure for ValidateUser to call. I copied over all my users from another table and encrypted all the passwords in the aspnet_membership table using the code below. My question is, how do I take the password the user enters in the login form and validate that against what is in my aspnet_membership Here is the code I used to encrypt the passwords (not even sure this was the right way to encrypt. Please tell me if I did this wrong):
public static string EncodePasswordNow(string originalPassword) { Byte[] originalBytes;
I use access membership prvider and it works. but I am unable to recover passwork. It says that "" membership provider doesn't support to get and zero password." It gives me the error in turkish and I translated it. Something like that. I am using the below code;
Does anyone has a solution (sample code) for the following features:
Create a randomGuid/Cryptographically strong random number Send a unique URL containing the random number to the user's email address When confirmed, the user is asked to change password
My provider is currently parametrized this way:
[code]....
The security issues with this type of procedure have been discussed here before.
It's new to me to use the membership provider class.I was able to inherits the MembershipProvider in my library(HDIMembershipProvider.vb) and a lot of functions are generated. When I created the form to create a user like this:
[Code]....
Once the user clicks submit, how this function can be called ?
I have a CreateUserWizard that uses the membership provider and creates a user in a sql server database.I need to change the IsApproved property on creation to false.I know that it can be done by createing a custom navigation template... but then i will have to code all the checks for the creation of the user...Is there any other way to access that attribute?this is the aspx code:
I am using the Membership provider that is included in Framework 3.5. I need to be able to add properties to the user such as country and birth date. I have read about the alternative provider that microsoft distibutes called TableProvider where you can define extra properties in the webconfig. I hesitate a bit about using it as there where some stuff about adding rules to the database to allow access. Since i use a hosted server and i am almost clueless about database administration it got me enough worried to think out my own solution. A. any feedback about using table provider from people that have experience of it?
I have a custom membership user class and custom MembershipProvider working against database. Due to security reasons the user passwords are stored in the database as hashed values. So my procedure
public override bool ValidateUser(string username, string password) is { //select hashed password from db return (EncodePassword(password) == dbpassword) } [code]....
I am trying to create a Forms Authenticated site and have already used the aspnet_regsql tool to create the necessary logic in my SQL Server DB to hold my data. Now, I am looking to create a custom Membership, User and Role provider for my DB model. I was looking at the following video: [URL]
Now, I get the concept on how to go about it but I notice that this guy uses custom DB Procedures as to the ones that are generated by the aspnet_regsql tool. Can anyone direct me on where I can find info on how to go about building the Membership, User and Role provider class using the DB structure that aspnet_regsql generates? So much junk on google that I am having a hard time finding good guidance.
I am creating a interface for User Role Management based on built in membership provider.I want to display all the roles as check boxes for a selected user. I am able to display all the roles in the database, but not able to load the specific user roles. For example, I am able to publish role 1 role 2 role3 role 4 as check boxes. But if the user is already flagged as role 1 and role 3, I am not able to show that data (role1 and 3 should be checked when form loads, but right now, they are not checked)...How do I get the roles as checked boxes display on a page.I am using a repeater control to display roles as check boxes on the page..
There seems to be something wrong with the create user wizard?I am using hashed password storage. When I change it to clear storage I see the user's password is being stored as something completly different than what they typed in.Example: changeme1 now equates to something like: 4W*KQQ4%=SIf I use 4W*KQQ4%=S as the password to login with it works but changeme1 does not.When I use the reset password wizard it updates the password just fine and it works when I login next.Any clues what could be causing this?
Do I need to make a Custom Membership Provider or is there another way?
I have a project using ASP.NET Forms Authentication and the Microsoft SQL Membership Provider. The website is DONE. I use this provider everywhere. (Register, Login, Forgot Password, etc...) Until now, my website users have not needed complex passwords. The users' passwords were really just pins. The user could select anything for a password in the past. I had almost no restrictions for this website because none of the data is private or personal. However I have received new requirements.
Here are the new password requirements:
Passwords must be at least 8 characters in length. Passwords must be created using 3 of the following 4 character types:
Uppercase Lowercase Numeric Punctuation
Do not use your name or User ID in the password. Do not use old passwords again later. Passwords must be changed at least every 60 days. Passwords may not contain your User ID or any part of your full name. Password history retention will prohibit use of the last 24 passwords. Passwords may be changed by users only once in any 6-day period.
I realize I am going to have to modify all of the following pages: Register, Login, Forgot Password, etc... fortunately I stopped using the default controls a long time ago.
My first thought was that I need to write a Custom Membership Provider. I don't know how to make the standard provider to do most of this. I could write code to do.
Do I modify the aspnet_membership table? Should I add my own table aspnet_something? Can the user profile table be used for this problem? Do I need my own MembershipUser class?
1. user can login by their AD account and password.
2. AD account can be assigned to different group.
I know there is a training video - [URL] to teach how to use the tool to provision the membership schema to SQL server for Forms authentication. but how can I use AD authentication with this?
i have implemented custom role provider and membership provider .
login page : SignIn.aspx
on successful login it redirects to (index-Homepage.aspx)
now PROBLEM is when it successfully logged in ,and redirects to 'index-Homepage.aspx' it gives Anornymoustemplate ..while its verifying the role correctly in index-Homepage.aspx.cs
1 - whats the difference between Role Provider and Membership provider ??
2- If we implement Custom Role Provider or Custom Membership provider then what does this means ? and which Provider do we use when we apply custom role provider or custom membership provider
i'm building an application and i need to manage roles, users and more things so i tought to use the membership provider but i have some questions about it: can i full extend it and can i override the functions to use a database table to store infos about config or i need to build my own provider?
I'm using a website as a frontend and all users are authenticated with the standard ASP.NET Membership-Provider. Passwords are saved "hashed" within a SQL-Database.Now I want to write a desktop-client with administrative functions. Among other things there should be a method to reset a users password. I can access the database with the saved membership-data, but how can I manually create the password-salt and -hash? Using the System.Web.Membership Namespace seems to be inappropriate so I need to know how to create the salt and hash of the new password manually.
I am using SQL Membership Provider to create user accounts for my web site and for some reason, the CreateDate and LastLoginDate fields are NOT saving the current time of my machine when I add a new user to the website. It is showing the previous day's date and the time is displayed as PM when it's AM and vise-versa in the CreateDate and LastLoginDate fields in aspnet_Membership table. I am developing and running the website via localhost on my laptop using IIS 7 (Windows 7). Does this have anything to do with my laptop's clock settings or is there something I need to configure in the web.config file or in IIS.
