.SH NAME
|
|
slapo-dynlist \- Dynamic List overlay
|
|
.SH SYNOPSIS
|
|
ETCDIR/slapd.conf
|
|
.SH DESCRIPTION
|
|
The
|
|
.B dynlist
|
|
overlay to
|
|
.BR slapd (8)
|
|
allows expansion of dynamic groups and more.
|
|
Any time an entry with a specific objectClass is being returned,
|
|
the LDAP URI-valued occurrences of a specific attribute are
|
|
expanded into the corresponding entries, and the values
|
|
of the attributes listed in the URI are added to the original
|
|
entry.
|
|
No recursion is currently allowed, to avoid potential infinite loops.
|
|
|
|
.SH CONFIGURATION
|
|
The config directives that are specific to the
|
|
.B dynlist
|
|
overlay must be prefixed by
|
|
.BR dynlist\- ,
|
|
to avoid potential conflicts with directives specific to the underlying
|
|
database or to other stacked overlays.
|
|
|
|
.TP
|
|
.B overlay dynlist
|
|
This directive adds the dynlist overlay to the current database,
|
|
or to the frontend, if used before any database instantiation; see
|
|
.BR slapd.conf (5)
|
|
for details.
|
|
|
|
.LP
|
|
These
|
|
.B slapd.conf
|
|
configuration options apply to the dynlist overlay. They must appear
|
|
after the
|
|
.B overlay
|
|
directive.
|
|
.TP
|
|
.B dynlist-oc <objectClass>
|
|
The name of the objectClass that triggers the dynamic expansion of the
|
|
data. This statement is required.
|
|
.TP
|
|
.B dynlist-ad <attributeName>
|
|
The name of the attributeDescription that holds the LDAP URI values that
|
|
will expand; if none is present, no expansion occurs. If the intersection
|
|
of the attributes requested by the search operation (or the asserted attribute
|
|
for compares) and the attributes listed in the URI is empty, no expansion
|
|
occurs for that specific URI. This statement is required.
|
|
.TP
|
|
.B dynlist-member-ad <attributeName>
|
|
The name of the attributeDescription that will list the DN of the entries
|
|
resulting from the internal search. This statement is optional and, if
|
|
present, changes the behavior of the overlay into that of a dynamic group.
|
|
The <attrs> portion of the URI is ignored, and the DNs of all the entries
|
|
resulting from the expansion of the URI are listed as values of this
|
|
attribute.
|
|
|
|
.LP
|
|
The dynlist overlay may be used with any backend, but it is mainly
|
|
intended for use with local storage backends.
|
|
In case the URI expansion is very resource-intensive and occurs frequently
|
|
with well-defined patterns, one should consider adding a proxycache
|
|
later on in the overlay stack.
|
|
|
|
.SH EXAMPLE
|
|
This example collects all the email addresses of a database into a single
|
|
entry; first of all, make sure that slapd.conf contains the directives:
|
|
|
|
.LP
|
|
.nf
|
|
include /path/to/dyngroup.schema
|
|
# ...
|
|
|
|
database <database>
|
|
# ...
|
|
|
|
overlay dynlist
|
|
dynlist-oc groupOfURLs
|
|
dynlist-ad memberURL
|
|
.fi
|
|
.LP
|
|
and that slapd loads dynlist.la, if compiled as a run-time module;
|
|
then add to the database an entry like
|
|
.LP
|
|
.nf
|
|
dn: cn=Dynamic List,ou=Groups,dc=example,dc=com
|
|
objectClass: groupOfURLs
|
|
cn: Dynamic List
|
|
memberURL: ldap:///ou=People,dc=example,dc=com?mail?sub?(objectClass=person)
|
|
.fi
|
|
|
|
If no <attrs> are provided in the URI, all (non-operational) attributes are
|
|
collected.
