Regarding the cause of the issue, it seems we've identified the problem. 
The issue is the fact that the winbindd socket directory was never set, 
thus it was using /tmp/.winbindd and failing (in winbindd_pipe_sock in 
libcli/wbclient.c).

The reason the tests didn't fail was because it managed to set it 
correctly with the environment variables.

The fix is minor, which is just to add the missing cflags in the 
wscript_build file which include the necessary winbindd socket directory.

Attached is also a patch by Andrew to ensure this doesn't happen again.


Cheers,
