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.

At last I find the answer of my question. This class convert the byte[] to valid security descriptor com object.
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);
