They must appear +after the +.B overlay +directive. +.TP +.B lastmod-rdnvalue +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: +.LP +.RS 4 +( 1.3.6.1.4.1.4203.666.3.13 " + NAME 'lastmod' + DESC 'OpenLDAP per-database last modification monitoring' + STRUCTURAL + SUP top + MUST ( cn $ lastmodDN $ lastmodType ) + MAY ( description $ seeAlso ) ) +.RE + +.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. +.LP +.RS 4 +( 1.3.6.1.4.1.4203.666.1.30 + NAME 'lastmodEnabled' + DESC 'Lastmod overlay state' + SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 + EQUALITY booleanMatch + SINGLE-VALUE ) +.RE + +.SH OPERATIONAL 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. +.P + +.B lastmodDN +.P +This attribute contains the distinguished name of the entry +that was last modified within the naming context of a database. +.LP +.RS 4 +( 1.3.6.1.4.1.4203.666.1.28 + NAME 'lastmodDN' + DESC 'DN of last modification' + EQUALITY distinguishedNameMatch + SYNTAX 1.3.6.1.4.1.1466.115.121.1.12 + NO-USER-MODIFICATION + USAGE directoryOperation ) +.RE + +.B lastmodType +.P +This attribute contains the type of the modification that occurred +to the last modified entry. Legal values are +.BR add , +.BR delete , +.BR exop , +.BR modify , +.B modrdn +and +.BR unknown . +The latter should only be used as a fall-thru in case of unhandled +request types that are considered equivalent to a write operation. +.LP +.RS 4 +( 1.3.6.1.4.1.4203.666.1.29 + NAME 'lastmodType' + DESC 'Type of last modification' + SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 + EQUALITY caseIgnoreMatch + SINGLE-VALUE + NO-USER-MODIFICATION + USAGE directoryOperation ) +.RE + + +.SH EXAMPLES +.LP +.RS +.nf +database bdb +suffix dc=example,dc=com +\... +overlay lastmod +lastmod-rdnvalue "Last Modification" +.fi +.RE + +.SH SEE ALSO +.BR ldap (3), +.BR slapd.conf (5), +.LP +"OpenLDAP Administrator's Guide" (http://www.OpenLDAP.org/doc/admin/) +.LP + +.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. + +.SH ACKNOWLEDGEMENTS +.P +This module was written in 2004 by Pierangelo Masarati in fulfillment +of requirements from SysNet s.n.c.; this man page has been copied +from +.BR slapo-ppolicy (5), +and most of the overlays ever written are copied from Howard Chu's +first overlays. +.P +.B OpenLDAP +is developed and maintained by The OpenLDAP Project (http://www.openldap.org/). +.B OpenLDAP +is derived from University of Michigan LDAP 3.3 Release. -- cgit v1.2.3
