Hallo,

ich versuche gerade ein kleines Tool zu schreiben wo ich die Gruppen einer AD auslesen kann.

Kann mir einer Helfen wie ich eine Gruppe aus einer AD auslesen kann.

Ein kleiner Gruß

Hier sind so ziemlich alle Methoden die ich jemals benutzt habe.

#region LDAP Methoden

string ExistsInLdap(string userName)

{

DirectoryEntry searchRoot = new DirectoryEntry("LDAP://DEINE DOMAIN", "dein ADMINUSER", "pw des ADMINUSERS");

DirectorySearcher search = new DirectorySearcher(searchRoot);

search.Filter = String.Format("(SAMAccountName={0})", userName);

search.PropertiesToLoad.Add("cn");

search.PropertiesToLoad.Add("samaccountname");

search.PropertiesToLoad.Add("givenname");

search.PropertiesToLoad.Add("sn");

SearchResult result = search.FindOne();

string samaccountname = (string)result.Properties["samaccountname"][0]; //Kuerzel

string givenname = (string)result.Properties["givenname"][0]; //Vorname

string surname = (string)result.Properties["sn"][0]; //Nachname

string cn = (string)result.Properties["cn"][0]; //Vor und Nachname

if (result == null)

{

return String.Empty;

}

else

{

return samaccountname;

}

}

if (result != null)

{

int groupCount = result.Properties["memberOf"].Count;

for(int counter = 0; counter < groupCount; counter++)

{

int indexChar = groupsList.IndexOf(",");

string subString = groupsList.Substring(0,indexChar);

int indexChar2 = groupsList.IndexOf("=");

groupList.Add(subString.Substring(indexChar2+1,(subString.Length)-(indexChar2+1)));

}

}

return groupList;

Hallo yhsif,

danke für die schnelle Hilfe.

Habe es an mein Programm angepasst.

Danke

Hallo,

ich habe eine Funktion implementiert (wie hier die Funktion GetADGroupUsers(string groupName)), die die Benutzer einer Gruppe ausliest.

Mein Problem ist, dass ich den accountnamen jedes Users der Gruppe brauche, mit der Funktion jedoch der komplette Name ausgelesen wird.

kann mir da jmnd helfen?

Hier meine Funktionen zum Auslesen von Gruppen eines Users und die, die die User einer Gruppe auslesen soll.

Public Function GruppenEinesBenutzer(ByVal benutzer_id As String) As Collections.Generic.List(Of String)


        Dim searcher As DirectorySearcher = Nothing

        Dim colEntry As New Collections.Generic.List(Of String)


        searcher = New DirectorySearcher(New DirectoryEntry("LDAP://xxx.com"))

        searcher.Filter = String.Concat("(&(objectClass=User) (sAMAccountName=", benutzer_id, "))")

        searcher.PropertiesToLoad.Add("MemberOf")

        Dim result As SearchResult = searcher.FindOne

        Try

            For i As Integer = 0 To result.Properties("MemberOf").Count - 1

                Dim sProp As String = result.Properties("MemberOf")(i)

                colEntry.Add(sProp.Substring(3, sProp.IndexOf(",") - 3))

            Next

        Catch ex As Exception

        End Try

        GruppenEinesBenutzer = colEntry


    End Function

    Public Function UserInGruppe(ByVal grpname As String) As Collections.Generic.List(Of String)

        UserInGruppe = New Collections.Generic.List(Of String)

        Dim searcher As DirectorySearcher = Nothing

        Dim colEntry As New Collections.Generic.List(Of String)


        searcher = New DirectorySearcher(New DirectoryEntry("LDAP://xxx.com"))

        searcher.Filter = String.Concat("(&(objectClass=group)(|(cn=" & grpname & ")(dn=" & grpname & ")))")

        searcher.PropertiesToLoad.Add("memberof")


        Dim result As SearchResult = searcher.FindOne

        For Each tmp As String In result.GetDirectoryEntry().Properties("member").Value

            UserInGruppe.Add(tmp)

        Next

    End Function

Vielen Dank im Voraus
