[Mono-dev] System.DirectoryServices

[Daniel Peñalba Acitores]

There is a problem with the implementation of this library. 

Mono implementation of DirectoryServices uses a library provided by Novell (C# LDAP Library).

Getting the objectSID of a user or a group, I've seen that the Microsoft Framework library (DirectoryServices.dll) returns the SID as a byte[28].

Nevertheless, the length of the arrays with Novell Ldap Library are 27 in some cases, and 26 in other.

When the length is 27, the lost byte is the 14th (starting in 0).

When the length is 26, the lost bytes are 14th and 24th.

There is two examples in hex. The first column is the number of byte. The second column is each byte retrieved by Novell lybrary (hex), and the third column is each byte retrieved by Framework library.

I'm reviewing the code in order to find this bug.

If I have news, i will report this to this list.
