Hi,
I'm using Windows XP Professional with IIS. I developed Login page that authenticated user in Active Directory Services.
Here's some code,
----------------------------------
Public Function IsAuthenticated(ByVal domain As String, ByVal username As String, ByVal pwd As String) As Boolean
Dim domainAndUsername As String = domain + "\" + username
Dim entry As New DirectoryEntry(_path, domainAndUsername, pwd)
Try
' Bind to the native AdsObject to force authentication.
Dim obj As Object = entry.NativeObject
Dim search As New DirectorySearcher(entry)
search.Filter = "(SAMAccountName=" + username + ")"
search.PropertiesToLoad.Add("cn")
Dim result As SearchResult = search.FindOne()
If result Is Nothing Then
Return False
End If
' Update the new path to the user in the directory
_path = result.Path
_filterAttribute = DirectCast(result.Properties("cn")(0), String)
Catch ex As Exception
'----------error log
' Get current date and time
Dim dt As DateTime = DateTime.Now
Dim logFile As String = "C:\jai_logfiles\ADServicesClass.txt"
Dim logWriter As StreamWriter
'logFile = ConfigurationSettings.AppSettings["LogFilePath"];
If File.Exists(logFile) Then
logWriter = File.AppendText(logFile)
Else
logWriter = File.CreateText(logFile)
End If
logWriter.Write(dt.ToString("dd MMM yyyy HH:mm:ss").ToString() + " - Error at IsAuthenticated-->" + ex.Message)
logWriter.Close()
Return False
End Try
Return True

---------------------------------
I'm setup my IIS with
1. Under Anonymous access and authentication control - i clicked Edit...
2. Authentication Methods Dialog will diplayed.
3. I checked Anonymous access, then I set as follow,
Account used for anonymous access:
User: jai
Password: jai123
I'm unchecked Allow IIS to control password
Then, i clicked OK and OK again to close the property dialog.
---------------------------------------------------------------
When run the web application, i got error in my logfiles it shown
The requested authentication method is not supported by the server.
My question is,
1. What did i miss my asp.net code, web.config and IIS setting etc?
2. Did i need do something with configuration and setting at directory server to make sure requested authentication method is supported?
I'm really-really stuck.
