System.DirectoryServices.Protocols: Attributwert löschen

[Phoenix]

Ah.. habs selber:

Code:

var modification = new DirectoryAttributeModification();
modification.Name = "member"; // Attributname
modification.Operation = DirectoryAttributeOperation.Delete;

foreach (entry in list)
{
   if (NeedToDelete(entry)
      modification.Add(entry);
}

if (modification.Count > 0)
{
   try
   {
      var request = new ModifyRequest(LdapObject.DistinguishedName, modification);
      ModifyResponse response = (ModifyResponse)LDAPConnection.SendRequest(request);

      if (response.ResultCode != ResultCode.Success)
         throw new InvalidOperationException("Ldap Error: " + response.ErrorMessage);
   }
}

Damit werden nur die Werte aus dem Attribut gelöscht, die in der DirectoryAttributeModification angegeben wurden.
