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:///"
