Most of this is simply glibc and nsswitch doing their stuff.  The rest
is becouse we re-open smbd's own ldap connections per use.   However,
what you see is just glibc at work.

Try using ncsd if this bothers you.  Does this really affect
performance?  Just becouse somthing can be logged doesn't mean that its
a problem.
