+This directory contains slapd overlays specific to samba4 LDAP backend:
+
+ - rdnval
+
+
+ - RDNVAL
+
+This overlay maintains the operational attribute "rdnValue". It contains
+the value of the entry's RDN. This attribute is defined by the overlay
+itself as
+
+ ( 1.3.6.1.4.1.4203.666.1.58
+ NAME 'rdnValue'
+ DESC 'the value of the naming attributes'
+ SYNTAX '1.3.6.1.4.1.1466.115.121.1.15'
+ EQUALITY caseIgnoreMatch
+ USAGE dSAOperation
+ NO-USER-MODIFICATION )
+
+under OpenLDAP's development OID arc. This OID is temporary.
+
+To use the overlay, add:
+
+ moduleload <path to>rdnval.so
+ ...
+
+ database <whatever>
+ ...
+ overlay rdnval
+
+to your slapd configuration file. An instance is required for each database
+that needs to maintain this attribute.
+
+This overlay is only set up to be built as a dynamically loaded module.
+On most platforms, in order for the module to be usable, all of the
+library dependencies must also be available as shared libraries.
+
+If you need to build the overlay statically, you will have to move it into the
+slapd/overlays directory and edit the Makefile and overlays.c to reference
+it. You will also have to define SLAPD_OVER_SMBK5PWD to SLAPD_MOD_STATIC,
+and add the relevant libraries to the main slapd link command.
