I have a website that requires users to login, but I am having problems when authenticating a users.I create a user which works fine, I then test the login on the development machine and everything works fine the user is logged in.But if a try to login the user in via the live website (same database) I get errors stating that the login attempt has failed.I don't understand why it would work on the development machine but won't work with the live version of the website.

I am using Login control and validationg the user against SQL datasource. below is the code:
Protected
Sub Login1_Authenticate(ByVal sender
As
Object,
ByVal e
As System.Web.UI.WebControls.AuthenticateEventArgs)
Handles Login1.Authenticate
e.Authenticated = IsValidUser()If IsValidUser() =
True
Then
Response.Redirect("Orders.aspx")End
If
End
Sub
Here is IsValidUser
Private Function IsValidUser() As Boolean
Try
Dim sql As String = String.Empty
Dim RecCount As Integer = 0
sql = "Select count(*) from UserLogins where UserName='" & clsDB.RemoveQuote(Me.Login1.UserName.Trim) & "'"
sql = sql & " AND UserPass='" & Me.Login1.Password.Trim & "'"
RecCount = clsDB.ExeScalar(sql)
'If Invalid ==> 0 means no record is being returned by Query
If RecCount = 0 Then
IsValidUser = False
'MessageBox.Show("Invalid User Name/Password.", "Invalid", MessageBoxButtons.OK, MessageBoxIcon.Stop)
Exit Function
End If
If RecCount = 1 Then
IsValidUser = True
Exit Function
End If
'Error handler
Catch ex As Exception
End Try
End Function
Here comes the problem validation code is working fine and it validates the user and redirects the user to the "Order.aspx" page
For example: I type
Login Name: Nashy
Password: 1234
Order.aspx page has a textbox which supposed to display the current user login name and i am usiong the following code for that
textbox1.text=Web.HttpContext.Current.User.Identity.Name.tostring()
when i test it on my local PC it shows the current user like this DOMAIN ashyMastrew.. what i want that the textbox should disply "nashy" not my current windows login name. and when i deploy it to the server and access it from other pc textbox does not show anything.

I got a role call "Staff", staff registration is done by admin so when creating a new staff only need their name, user name, password and e-mail. After registering, i wan to redirect the staff to the creating profile page to input their contact number and self-description which is a must for later use. For first time login staff, how do i compare and see if the contact and description profile is empty or not? If it is empty, then redirect to the create profile page, else just go to staff page.
I trying to do like making each different role redirect to their own page once they had login. For now when the user login they will remain in the same page showing the login template. How do i do that?

How would I go about to solve this:
When the user clicks a button and the user has been inactive for too long (session is gone), then redirect the user to the login page and back to the current page after logging in?
Is there a built in solution to this or do I have to do it manually? If so, how?

In logout link's click event i have written Session.Abandon() that will destroy the Session state.I am also handling Session_End event that is fired afterward (written in Global.asax). But one more thing i want is that after Session ends, login page should be redirected (opened).
For that i wrote:
[Code]....
This is working fine on the surface, but after applying debugging i saw that there were unexpected number of calls to Session_Start and Session_End events for two times, then login page was opened.
Why Session_Start and Session_End was called two times ? If i left this process as it is working then may i get some serious error in future ?

For my current project I am using form authentication.What occasionally will happen is a user will timeout (unbeknownst to them),they try navigating to a different page (call it Page B) and they get kicked back to the login screen.This is fine and I have no problems with this.
However,after they enter their credentials and are authenticated they are redirected back to "Page B" and an error is produced because a session variable wasn't loaded. This is due to the fact that they were redirected to "Page B" instead of the page they would normally hit after a login (call it Page A).Is there anyway to force the user to go to Page A instead of Page B in these situation to avoid these errors?

i currently develop an asp.net mvc 2 web app using asp.net membership and role management for authenticating and authorizing my users. I get complaints though that when adding a role to some user, he is not able to see new role assigned functionality, unless he re-enters (logout and login again) the application.

I have a login status object on each page for logging out. Clicking on this object will logout the user and navigate to the login page. I would like to set it up when a page is loaded, if certain conditions are met the user will be automatically logged of and redirected to the login page. If I could just somehow have the program click on that object, that would do the job.

I need to create an application with Forms Authentication and/or Windows Authentication. If the application is set to use mixed authentication (Forms + Windows Auth) and the user don't have a Windows user account, the login will fail and he must be redirected to a forms login page. How can I do this?
Are there any different way to provide mixed authentication?

Ok, I have been trying with this for many days now and read countless posts on this subject but I still cannot get it working.
I have created 2 roles and memberships one for admin and one for users, as you can guess I want to direct admins to a admin page and users to a user page. When a user logs on, it works fine, whether it's an admin or user, but they both present the home page, default.aspx
I know you have to have a redirecturl, to direct the user to the relevant page, either admin or user, but where and which webconfig would you put this in? I have seen in some post that you need a protected void or a role line in a webconfig file, but I have tried both these and countless other bits of code in different webconfig files. Before you ask about validation, I know this works as the user can log in, but just wont go to the relevant page.
Directorty structue I have is as follows:
Account folder contains - ChangePassword.aspx, ChangePasswordSuccess.aspx, Login.aspx, Register.aspx, Web.config
Webconfig contains
[Code]....
Admin folder contains - default.aspx, Web.config
webconfig contains
[Code]....
Registered folder contains - default.aspx, Web.config
webconfig contains
[Code]....
