+.SH NAME
+slapo-lastmod \- Last Modification overlay
+.SH SYNOPSIS
+ETCDIR/slapd.conf
+.SH DESCRIPTION
+.LP
+The 
+.B lastmod
+overlay creates a service entry rooted at the suffix of the database
+it's stacked onto, which holds the DN, the modification type,
+the modifiersName and the modifyTimestamp of the last write operation
+performed on that database.
+The lastmod overlay cannot be used when the "lastmod" feature
+is disabled, i.e. "lastmod off" is used.
+.P
+All operations targeted at the DN of the lastmod entry are rejected,
+except reads, i.e. searches with 
+.B base
+scope.
+Regular operations are ignored, unless they result in writing; then,
+in case of success, the lastmod entry is updated accordingly,
+if possible.
+
+.SH CONFIGURATION
+These 
+.B slapd.conf
+configuration options apply to the lastmod overlay. They must appear
+after the
+.B overlay
+directive.
+.TP
+.B lastmod-rdnvalue <RDN value>
+Specify the value of the RDN used for the service entry.  By default
+.I Lastmod
+is used.
+.TP
+.B lastmod-enabled {yes|no}
+Specify whether the overlay must be enabled or not at startup.
+By default, the overlay is enabled; however, by changing the boolean
+value of the attribute
+.IR lastmodEnabled ,
+one can affect the status of the overlay.
+This is useful, for instance, to inhibit the overlay from keeping track
+of large bulk loads or deletions.
+
+.SH OBJECT CLASS
+The 
+.B lastmod
+overlay depends on the
+.B lastmod
+objectClass.  The definition of that class is as follows:

+.SH ATTRIBUTES
+.P
+Each one of the sections below details the meaning and use of a particular
+attribute of this
+.B lastmod
+objectClass.
+Most of the attributes that are specific to the lastmod objectClass are
+operational, since they can logically be altered only by the DSA.
+The most notable exception is the
+.I lastmodEnabled
+attributeType, which can be altered via protocol to change the status
+of the overlay.
+.P
+
+.B lastmodEnabled
+.P
+This attribute contains a boolean flag that determines the status
+of the overlay.  It can be altered via protocol by issuing a modify
+operation that replaces the value of the attribute.

+This attribute contains the type of the modification that occurred

+and
+.BR unknown .
+The latter should only be used as a fall-thru in case of unhandled

+
+.SH BUGS
+It is unclear whether this overlay can safely interoperate 
+with other overlays.
+If the underlying backend does not implement entry_get/entry_release
+handlers, modrdn update can become tricky.
+The code needs some cleanup and more consistent error handling.
+So far, the OIDs for the schema haven't been assigned yet.
