Hi all,

I really need your help on this problem. (no help for 1 day goolging).

I use form authentication on my 2 simple aspx pages.
User is redirected to login.aspx, then see the main content page.
I use LDAP to verify the user from a domain named Dserver where the AD users locate.

Everything works just fine on my laptop (localhost). I could verify the user from the Active Directory. I am also able to verify whether the user belongs to a group named AllowDogs and redirect accordingly (main content page or fail-message).

Problem: As I move this application to an existing IIS win2k3 std box, I failed to verify user from the Dserver. I got the error message "The server is not operational"

Here is my IsAuthenticated code:

Public Function IsAuthenticated(ByVal domain As String, ByVal act As String, ByVal ps As String) As Boolean

Dim domainAndAct As String = domain & "\" & act

Dim entry As DirectoryEntry = New DirectoryEntry(_path, domainAndAct, ps)

Try

Dim obj As Object = entry.NativeObject

Dim search As DirectorySearcher = New DirectorySearcher(entry)

search.Filter = "(SAMAccountName=" & act & ")"

search.PropertiesToLoad.Add("cn")

Dim result As SearchResult = search.FindOne()

If (result Is Nothing) Then

Return False

End If

'update the path to the user in the directory

_path = result.Path

_filterAttribute = result.Properties("cn").Item(0)

Catch ex As Exception

'Throw New Exception("Error authenticating user: " & ex.Message)

Return False

End Try

Return True

End Function

Thank you all for help/reading
