I am sorry, I think my question was not clear, Let me try to explain my self better.

I have created a website using asp.net 4.0, I have also created a windows application using vb.net 3.5.  The windows application is used in a number oif offices that are not connected. At one time this office have to connect to the website and upload or download information from other offices. They open the website though the windows application and that is working fine..

My challenges.

Because, there is a lot of security issues with the data at the website.  The website should know who has logged in and what data access security level he owns in order to determine what information should be made accessinble to them.

I am thinking that, at the time I open the website I should supply some information that the website will use to determine what information to display.

It sounds like you might benefit from using LDAP/Active Directory to authenticate users.  You could control what content is visible to the user based off of the OU that they're a member of.

Alternatively, you could manage this yourself by keeping a database of sorts with a list of users and the types of information that you want them to be able to see.  It sounds like you already have some kind of login mechanism put together, so you might just need to extend it to include the idea of user groups where you can dictate what data is visible to what users/groups.

Yes I have the login mechanism with the windows application and it is fine and has good control of who access what. I would not want to create a similar table with the website database because it may be difficult for the client/users to have the two fully synclonised all the time. I want to open the website with the user login details and be able to determinie what information he/access can access.

Thanks
