No, not at all!
I don't think your build is the problem.

I was just trying to explain why I think that winbindd may
be started with slighly different parameters from the samba
daemon than when it is launched directly.

We need to get the config parameters straight, and then,
when we have identified the problem and possibly created
a patch for the code, then you will need to recompile. ;-)
