Sponsoring a canon_user plugin for LDAP lookup

[Dan White]

Right. The SASL/EXTERNAL was a copy and paste error, the
command was supposed to end with '...u:dwhite'. The -U
was unnecessary. This command does the same thing:

ldapwhoami -Y EXTERNAL -X u:dwhite

The contents of my /etc/ldap/ldap.conf file are:
=========
BASE    dc=nodomain
URI     ldapi:///
=========

and I forgot to mention that I modified /etc/default/slapd
like so, so that slapd listens on ldapi:

SLAPD_SERVICES="ldap:/// ldapi:///"
