There two things here.

One can be ignored as I completely forgot that libwbclient from 3.6
cannot work against winbindd from 4.0 due to protocol difference. So
the patch is moot.

Another is for what I need to use libwbclient from samba 4.0. Note
that I'm talking about nsswitch/libwbclient, not source4/ code.

I'm currently working on a python bindings for libwbclient, These
bindings will be needed for allowing FreeIPA to resolve user/group
names from trusted domains to SIDs before storing SIDs as part of
manual group mapping. Since schannel is in use by winbindd already for
trusted domains case, Guenther explained to me it will be problematic
for two schannel connections from the same host to coexist without
getting Windows confused (winbindd one and the one FreeIPA python code
would otherwise create using samba python bindings). So I need to talk
to the winbindd running on the host from Python code.
