I'm writing a program in Java, using Spring-LDAP. I need to implement a method, which should search a user by SID. For this reason I use a filter like "&((objectClass=User)(objectSid="+sid+"))". The search doesn't work with sid in String format like "S-1-12-345677-5676743-223344-...".

Using Apache Directory Studio, I can query my AD LDAP database regulary using a filter like: (objectSid=\ff\01\03\04\1a\2b\...) successfully. Here is the objectSid in hexadecimal format.

Now, how to translate the SID from String to hexadecimal and vice versa in a program, in Java?

There's the convertSidToStringSid and convertStringSidToSid methods in the Advapi32Util class.

I'm not sure if that'll be the exact formats you need, but hopefully will get you closer.

And here's an blog post that describes the SID format which might be helpful.
