Great, I'll hopefully post the patch during the next week.

And one more question. There is an Active Directory search
functionality in winbind, but it's not available through
request/response interface. So, I think it is one more thing
that could be extremely useful for applications that use Samba
for integration with windows on *nix environment.

I'll prepare the patch for this as well, so we'll be able to
discuss it more closely.
