Security :: How To Authenticate Users With Existing Login Control Mechanism
Feb 5, 2011
we have a web site (Web Site 1) which is presently working and authenticates the users using ASP.Net login control.
We have a new site (Web Site 2) which will have a web page with user name and password fields and these values will be posted to Web Site 1. I am trying to authenticate those user credentials on Web Site1 using
Membership.ValidateUser(UserName, Password); method. but i am keep getting "User AuthenticatedObject reference not set to an instance of an object. " exception.

I have been asked to use the login control to authenticate users to use the website. I have a master page which has header pictures and a menu down the left. I have created a login form and configured my web.config file to use form authentication but when I run it, it does not show my master page just the content page. Should my login page not be a content page?

I've set the NTFS security permission for each user and his/her domain to the webserver's security ntfs permission folder. But it is still not authenticating. So what do I need to do to enable this feature? I am using windows 2003 webserver.

I am working on an app where users are only allowed access if they click through from certain URLs. I.e. I need to authenticate by using the referral url and I am using
Request.UrlReferrer to achieve this.
I am guessing that the Request.UrlReferrer can be tampered with by malicious users to gain access...

I need to authenticate users based on three parameters such as username, password and officename instead of just username and password. User name is unique only across the single office and not across the application.
Can I achieve this using Membership class and if yes do I need to write any custom code for that?

I am trying to modify my current page to have a login. My Current page has the user select a store via a drop down List. This DDL will need to be used as the user name. I would liketo add a Password textbox and the end of the page that the user would just type in there password and hit submit to submit the form is correct or pop-up that passowrd is incorrect and re-enter. I would like to use a Database on my SQL Server to autenticate the passwortd with the store. Does anyone have any sample code that will accomplish this.

question about how to use MS Access as the aspnetdb.mdb during a login and authentication with the use of VS 2010 with framework 3.5. Reason: My current provider does not support MS SQL and only ms Access and MySQL as databases.I wanted to implement a login and authentication and based upon an artikel about ASP.net 2.0 i saw, that basically Access was the first choice in those days.Is it still possible to use Access? and how to implement this?Is this a matter of using connectionstrings inside web.config with Microsoft.ACE.OLEDB.12.0 ?Hope that i get an answer which i understand, since my knowledge about these things is not that big.

I am creating a Web Application in asp.net 2.0 and sql server 2005.I want to use an existing database.
I have created a login and a signup page. Then i replace the new SQL database (the one that is created automaticly by the visual studio) with the exiting database I have.If I create a new user, the new user goes to the database and I can login with the new user. I cannot login with the existing users.If I go to the asp.net configuration, I only can see the new users I have created, I cannot see the users that were in the database already and I can't see the roles also.
I can I make the new application to recognize the users and roles of the existing database?

i used security in login page which restricts all users who have not logged in to all pages. I need to restrict specific users to specific pages. I'm not using AspSqlService provider. So i cannot create roles and restrict automatically. And the pictures i use in login page are not visible @ runtime.

I dont know where to start, but I have a simple issue that you may be able to resolve.
I have a SQL database that contains a table with user name / password / Account level in it.
What I am trying to do is to create a Login page that will use this database and table to authenticate the login.
I have spent some time looking about for an example, and the nearest that I have found is for an access Database, but I really need this to work with SQL.
