I can see a few cases where a client might want to bind the
local address, for instance, to ensure use of a particular
network interface.

However, my concern with patch is one of the approach taken
to accommodate this binding.  I'm thinking it might be better
to provide an alternative to ldap_initialize(3) which takes
a connected descriptor instead of a URL.  Then calling program
can do whatever it pleases before its used by slapd(8).
