Get User or Group by objectSID Filter

[SD]

Hi,

I would like in c# get a user or a group using objectSID ref.

sample:
******
DirectoryEntry de = Utility.GetDirectoryObject();

DirectorySearcher deSearch = new DirectorySearcher();

deSearch.SearchRoot = de;

deSearch.Filter = "(&(objectClass=group)(objectSid=" + SID + "))";

SearchResult result = deSearch.FindOne();

My problem :
**********
I have a SID value in byte[] type. What sort of string value I have to put
in my filter and how to obtain it?

Thanks a lot

We have some good coverage of this topic in our new book, which you can find
linked to here:

www.directoryprogramming.net

Basically, a binary LDAP filter is constructed by taking each byte and
converting it to a hex character pair, preceding each byte with a "\". You
can use the .NET "X2" format string do this.

There is a function in the code samples from the book called
BuildFilterOctetString which you can download from the site above that
demonstrates this.
