Cómo establecer AccountExpires en VB.NET a través de AD DirectoryEntry (2)

Necesitaba establecer la propiedad accountExpires en AD DirectoryEntry no pudo encontrar una respuesta simple. Encontrado algo de información;

Vi algunos artículos con ADS ****. Dll pero no pensé que necesitaba usar este método

Dim valueToSet As Date = Now.AddDays(10) Dim ADSPath As String = "LDAP://cn=..." Dim de As DirectoryEntry = New DirectoryEntry(ADSPath) Dim d As TimeSpan = valueToSet.ToUniversalTime - Date.Parse("01/01/1601") Dim ValueToSetAsString As String = d.Ticks.ToString '' it appears that the ticks value is too large for the value of the directory entry '' converting to a string (18 chars or so) works! de.Properties("accountexpires").Value = ValueToSetAsString

Gracias a Brian, parece que la gran cantidad de código que se escribió anteriormente se puede simplificar;

de.Properties("accountexpires").Value = valueToSet.ToFileTime.ToString

Una función para devolver AccountExpires y otros problemas de LargeEnnte en VB.NET

Function ConvertADValueToDateTime(ByVal li As Object) As DateTime '' http://bytes.com/topic/visual-basic-net/answers/512901-lastlogontimestamp Try Dim lngHigh = li.HighPart Dim lngLow = li.LowPart Dim lastLogon = (lngHigh * 2 ^ 32) - lngLow Dim returnDateTime As DateTime = DateTime.FromFileTime(lastLogon) Return returnDateTime Catch ex As Exception Return Nothing End Try End Function

Ejemplo de uso:

Dim d As DateTime = ConvertADValueToDateTime(de.Properties("accountexpires").value) If d = "01/01/1601" Then '' no expiry date Return Nothing Else Return d End If

Un método alternativo

Convertir cuentas LDAPExpires a DateTime en C #


Algo como esto configurará el vencimiento de su cuenta en 30 días:

Dim de As New DirectoryEntry("LDAP://cn=foo,cn=users,dc=contoso,dc=com") de.Properties["accountExpires"].Value = DateTime.UtcNow.AddDays(30).ToFileTime() de.CommitChanges()


Esto usa DateTimePicker en un formulario, pero debería ser trivial usar cualquier otro formato de fecha.

Imports System.DirectoryServices Imports System.DirectoryServices.ActiveDirectory Imports System.IO ''Get the user Dim EntryString As String EntryString = "LDAP://...." Dim dirEntry As DirectoryEntry dirEntry = New DirectoryEntry(EntryString) Dim dirSearcher As New DirectorySearcher(dirEntry) dirSearcher.Filter = "(&(objectCategory=Person)(objectClass=user)(SAMAccountName=" & Trim(Form1.AccountNameTB.Text) & "))" dirSearcher.SearchScope = SearchScope.Subtree Dim searchResults As SearchResult = dirSearcher.FindOne() ''Set the date Dim d1 As Date = Form1.AccountExpiresDTP.Value Dim d2 As New DateTime(d1.Year, d1.Month, d1.Day) d2 = d2.AddDays(1) ''Add one day so that it matches what is in AD Dim ft As Long = d2.ToFileTime() dirEntryResults.Properties("accountExpires").Value = ft.ToString ''You do need to turn it into a string dirEntryResults.CommitChanges() dirEntryResults.Close()
