The retro changelog is created in the directory tree under a special suffix,
cn=changelog
.
The procedure for enabling the retro changelog plug-in from Directory Server Console is the same as
for all Directory Server plug-ins. For information, see
Section 16.2, “Enabling and Disabling Plug-ins”

8.16.2. Trimming the Retro Changelog
The entries in the changelog can be automatically removed after a specified period of time. To
configure the period of time after which entries are automatically deleted from the changelog,
set the
nsslapd-changelogmaxage
configuration attribute in the
cn=Retro Changelog
Plugin,cn=plugins,cn=config
entry.
The
nsslapd-changelogmaxage
attribute is a single-valued attribute. Its syntax is as follows:
nsslapd-changelogmaxage: Integer timeUnit
Integer
is a number, and
timeUnit
can be
s
for seconds,
m
for minutes,
h
for hours,
d
for days, or
w
for
weeks.
NOTE
There should not be a space between the
Integer
and
timeUnit
variables. The space in
the syntax above is intended to show that the attribute value is composed of two variable
parts, not just one. For example:
nsslapd-changelogmaxage: 2d
8.16.3. Searching and Modifying the Retro Changelog
The changelog supports search operations and is optimized for searches that include filters of the form
(&(changeNumber>=X)(changeNumber<=Y))
.
As a general rule, do not perform add or modify operations on the retro changelog entries, although
entries can be deleted to trim the size of the changelog. Only modify the retro changelog entry to
modify the default access control policy.
8.16.4. Retro Changelog and the Access Control Policy
