svn commit: r294543 - head/usr.sbin/ypldap

[Marcelo Araujo]

Author: araujo
Date: Fri Jan 22 03:02:38 2016
New Revision: 294543
URL: https://svnweb.freebsd.org/changeset/base/294543

Log:
  Switch from FD_SETSIZE to getdtablesize(2) as it can make the FD to be
  tunable. Also it gets more close with the original implementation from
  OpenBSD.
