Always results in socket connect failed.

Using the examples from the source tree:
modulepath	/usr/lib/ldap
moduleload	back_sock.so
include		/etc/ldap/schema/core.schema
database	sock
socketpath	/tmp/example.sock
suffix		"dc=test,dc=com"

Starting slapd:
slapd -4 -f /etc/ldap/slapd.conf -u root -g root -d1

Using the perl script example from the source tree plus tried endless debugging
with my own code. File permissions all look correct. 

Scoured for answers. 

Stumped.

Always: socket connect(/root/example.sock) failed
