NAME

slapo-emptyds - Remove Empty values from Directory String attributes Overlay to slapd

SYNOPSIS

ETCDIR/slapd.conf

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.

	dn: cn=alex,cn=people,dc=example,dc=org
	changeType: add                  changeType: add
	sn: <empty>              -->     sn: blah
	sn: blah
	dn: cn=alex,cn=people,dc=example,dc=org
	changeType: modify               changeType: modify
	add: sn                  -->     add: sn
	sn: <empty>                      sn: blah
	sn: blah
	dn: cn=alex,cn=people,dc=example,dc=org
