matching leading space in uid lookup

[Duncan Brannen <dbb@st-andrews.ac.uk>]

Hi All,
	I've a problem with OpenLDAP ignoring leading spaces when matching a uid.

Here's the problem...

We're running samba 2.2.8a as a PDC for windows classrooms with an LDAP 
backend.

What's happening is that users are waking up the windows machines by 
pressing the
space bar and then logging in.  They authenticate successfully (leading 
spaces ignored)
but windows is miscreating the roaming profiles with leading spaces which 
causes the
folder structure to be created incorrectly.

This causes profiles to be created in the root of C: rather than in 
Documents and Settings.
folder.

The Ldap server log looking up a username without the space but Samba shows
it asking for the username with a space.

Running OpenLDAP 2.1.19

It's it a bug / feature or something I can change in a config file / schema

Cheers,
	Duncan
