Using Built-in Windows Auth

I want to make users login to my programs but do not want them to have to remember another password. I don't want them to have to logoff the current windows session either.

Example:

Worker A is logged into windows but Manager 1 needs to show User A a report that he does not have permission to bring up. So, using the same login and password that is used to log into windows Manager 1 logs into the program and pulls up the report while Worker A remains logged into the computer.

Anyone know how verify windows 200 users/passwords using VB.net?

If there is its with the Principal and Identity objects in the System.Security namespace, try searching the help for 'Impersonating and Reverting'.

This may do what you want.

VB Code:

Public Function VerityUser(ByVal UserName As String, ByVal Password As String, ByVal Domain As String) As Boolean
        Try
            Dim Entry As DirectoryEntry = New DirectoryEntry("LDAP://" & Domain, UserName, Password)
            Dim Search As DirectorySearcher = New DirectorySearcher(Entry)
            Dim results As SearchResult
            results = Search.FindOne
            Return True
        Catch Err As Exception
            Return False
        End Try
    End Function
