From f5ebc8e404f4397c0ef2c8b838984df1767c955c Mon Sep 17 00:00:00 2001
From: Simo Sorce <idra@samba.org>
Date: Sat, 4 Feb 2006 00:38:48 +0000
Subject: r13324: From now on check attribute names obey rfc2251 Also add a way
 to provide utf8 compliant functions by registering them with
 ldb_set_utf8_fns()

Next comes code to register samba internal utf8 functions.

Simo.
