Authnetication and getRemoteUser()

[Emil Karlsson]

Hi,
I wondering if it is possible to get user username the user has logged on to his w2k with and then use it in a servlet/jsp?
More precisly is it like this I want to do:
1. When a user clicks on a link, his w2k username is fetched and checked against some data that is is stored in a dataset.
2. If the dataset contains the username it will display the desired page. If NOT the dataset contains the username it will display a message page.
-- in other words I don't want to have some username/password to be entered?
Is it possible and if so, how?

To get the user name you will have to make a native call to a Windows dll. The function you need is WNetGetUser in MPR.DLL. Chech the WinAPI from Micro$oft for details.
I have not coded it in Java, but here it is in VB:

Declare Function WNetGetUser& Lib "Mpr" Alias "WNetGetUserA" _
(lpName As Any, ByVal lpUserName$, lpnLength&)
Function GetUserName() as String
Dim cbusername As Long, username As String
' Windows 95+ - call WNetGetUser to get the name of the user.
username = Space(256)
cbusername = Len(username)
ret = WNetGetUser(ByVal 0&, username, cbusername)
If ret = 0 Then
' Success - strip off the null.
GetUserName = Left(username, InStr(username, Chr(0)) - 1)
Else
GetUserName = ""
End If
End Function
