Dear All,
I have read a lot of articels and infos about the authentication but i found no hint where my problem was descripted.
My problem is, I have a intranet application and my authentication is "Windows".
It works perfect but how can I handle if on a windows client another user as the windows user was logged into my web application?
That mean i need a logout for the actual webapplication and a relogin with another user (DomainUser).
Is this possible?
Did I need a mix from Windows - authentication and Form authentication?
Thanks for your Help

Windows Authentication means, Authenticating the User from Active Diretory.
If you set authentication mode as windows, A popup will ask for user name and password for the user. Which should be the DomainName\UserName and Password.
User who is not under that domain in which your application is hostes will not able to access the site.

Hello,
if i connect from a client which was not inside my domain a popup in the IE ask for user and passwort. That's right because i have customized my IIS to "Windows Integrated security".
If the client was in my Active Directory no popup occur. That's also ok.
But, and that is my main question how can i handle if the client is already connected with a windows user which is in the active directory for example "GASTUSER" and now another user will login with his own user "USERXXX" and his one security settings but without relogin on the client pc. Only Logout for the intranet application and Login with user "USERXX".
I tried this with Form Authentification and a connection to my LDAP but it's not really fast and we have a lot of directory with different users.
Maybe the solution is very easy but i have no idea.
Bye

You can mix them. Use the standard ASP.NET login controls and handle the authentication request on your own. You can use AD to authenticate or some other credential system.
only two letters away from being an asset

Hello Mark,
if i understood correct.
1. The IIS is configured with "Integration Windows authentication"
2. I have created a standard ASP.NET login control.
In the web.config the setting authentication = "Forms" and i have a Login and a Default URL defined.
I added a new Provider: System.Web.Security.ActiveDirectoryMembershipProvider with the connection string to my Active Directory.
In the default.aspx i check if the User.Identity.IsAuthenticated if yes a lot of settings was set.
So now have the user the possibility to logout. If the user click to logout i to the following
"FormsAuthentication.SignOut() and Response.Redirect("tomylogin.aspx")"
In the "tomylogin.aspx" the stanard ASP.NET login control exists. If the user inserting User and Passwort and click on logon the figures was checked because of the settings in the web.config (Active Directory String....). Is the user authenticatet a redirect to my default.aspx was execute.
My problem now is
1. the first check with the Active Directory is very very slow (i think we have to much users and structurs in the ADS).
2. Is this the correct way for a logout and login to my intranetpage?
3. Can i handle this easier?
Thanks for your help.
best regards
gitschi

The control which you are creating dynamically, you need to created before Page_Load(), other wise, it will not able to maintain the View State Data or will not load the Postback Data.
If you deeply look inside ASP.NET Page Life Cycle, Before Page_Load(), there are two different methods calls. 1) LoadViewState() and 2)LoadPostbackData().
So, if you create any control on Page_Load(), or after that it will not able to load the data.
So you need to create such control either in Pre_Init() or Init() method.
Though there are workaround to add the Control which are created after page_load into Control Tree for maintaining viewstate and Postback, using Catch up. I am not discussing that over here.
Hope this will help you in longer run

Use Page_Init or OnInit for adding dynamic control otherwise you need to manually maintain the view state.

In ASP.NET 2.0 you can use Page_Init or can override OnInit.

you seem a little thick. You are posting the same question day after day. Day after day, you get the same answer, which assumes that you're using .NET 3.5. You know you're not, so you need to make that clear. In any case, every day, you're being given the same information. Are you just blindly asking this day after day, without ever writing any code ? Post the code you've written, so we can help you progressively, instead of people giving you the same answer, every day.

What does it mean ? Are you getting any error ? or what ?
You are talking about Hosting on IIS or Running your Application From Visual Studio ?

Yes ! That's why I asked you the question, what is the problem if you are hosting on server, you have to give Write Access permission to that folder where you are uploadinf the file.

Always rememebr this rule of thumb:
Everyapplication can have one and only one Main function.
Search in your code, it looks that there are multiple main functions are defined.

This has nothing at all to do with ASP.NET. You want the C# forum. You should work through a basic book rather than trying to copy code off the web.
