.SH NAME
slapo-emptyds \- Remove Empty values from Directory String attributes
Overlay to slapd
.SH SYNOPSIS
ETCDIR/slapd.conf
.SH DESCRIPTION
Some non-conformant clients will provide empty values for Directory String
attributes with certain operations. This overlay makes empty values acceptable
for the Directory String syntax and will adjust all operations to make sure
these values are never actually stored in the database.
