<h4 id="rzahynestedgp">Nested groups</h4>
|
||
|
|
<p>The nesting of groups enables the creation of hierarchical relationships
|
||
|
|
that can be used to define inherited group membership. A nested group is
|
||
|
|
defined as a child group entry whose DN is referenced by an attribute contained
|
||
|
|
within a parent group entry. A parent group is created by extending one of
|
||
|
|
the structural group object classes (<span class="bold">groupOfNames</span>, <span class="bold">groupOfUniqueNames</span>, <span class="bold">accessGroup</span>, <span class="bold">accessRole</span>, or <span class="bold">groupOfURLs</span>) with the addition of the <span class="bold">ibm-nestedGroup</span> auxiliary object class. After nested group extension, zero or more <span class="bold">ibm-memberGroup</span> attributes can be added, with
|
||
|
|
their values set to the DNs of nested child groups. For example:</p>
|
||
|
|
<pre class="xmp">dn: cn=Group 2, cn=Groups, o=IBM, c=US
|
||
|
|
objectclass: groupOfNames
|
||
|
|
objectclass: ibm-nestedGroup
|
||
|
|
objectclass: top
|
||
|
|
cn: Group 2
|
||
|
|
description: Group composed of static, and nested members.
|
||
|
|
member: cn=Person 2.1, cn=Dept 2, cn=Employees, o=IBM, c=US
|
||
|
|
member: cn=Person 2.2, cn=Dept 2, cn=Employees, o=IBM, c=US
|
||
|
|
ibm-memberGroup: cn=Group 8, cn=Nested Static, cn=Groups, o=IBM, c=US</pre>
|
||
|
|
<p>The introduction of cycles into the nested group hierarchy is not allowed.
|
||
|
|
If it is determined that a nested group operation results in a cyclical reference,
|
||
|
|
either directly or through inheritance, it is considered a constraint violation
|
||
|
|
and therefore, the update to the entry fails.</p>
