Right. 64f5e24100a764ec198cab9a8d2c43fa86e7027c is a good
example where this has worked out. If it is a genuine
upstream bug, we should touch upstream.

But that being said, the patch is still inconsistent
in that it fills the standard libpaths in wafsamba but
does the filtering based on that in wafadmin. I mentioned
that explicitly in the mail and commit msg. The patch is
more a proposal for working on a final patch....

I still need to find the place to do the proper filtering
in wafsamba - this will be somewhat more involved, since
we need to parse the flags for -L$PATH ... but doable.

Cheers - Michael
