  Property value returned by DirectorySearcher and SearchResponse are of different type System._com...

  Nov 19, 2012 05:57 AM|LINK

  Hi,
  I am working on a website to manage active directory. I want to check that whether user has permission to change password or not.
  So I have to find "ntSecurityDescriptor" property value after that I have to cast it into IADsSecurityDescriptor.
  Now if I use DirectorySearcher class then property value is of type System._ComObject and easily casted to IADsSecurityDescriptor.
  But when I use LdapConnection and SearchResponse I get property value of type byte[] array which is unale to cast to IADsSecityDescriptor. I am getting error 
  "Unable to cast System.Byte[] to IADsSecurityDescriptor".
   
  Is there some problem with SearchResponse or I have use some kind of casting technique to achieve this. 
  I have some problem to use DirectoryEntry class so I can only use LdapConnction class.
   
  Please help its urgent.
  Thanks.

  ActiveDs.ADsSecurityUtility secUtility = new ActiveDs.ADsSecurityUtility(); ActiveDs.IADsSecurityDescriptor sd = (IADsSecurityDescriptor)secUtility.ConvertSecurityDescriptor((byte[])attribute[0], (int)ADS_SD_FORMAT_ENUM.ADS_SD_FORMAT_RAW, (int)ADS_SD_FORMAT_ENUM.ADS_SD_FORMAT_IID);
