<h2 id="rzahyuniqueatt">Unique attributes</h2>
|
||
|
|
<p>The unique attributes function ensures that specified attributes always
|
||
|
|
have unique values within a directory. These attributes can be specified in
|
||
|
|
two entries only, cn=uniqueattribute,cn=localhost and cn=uniqueattribute,cn=IBMpolicies.
|
||
|
|
Search results for unique attributes are unique for that server's database
|
||
|
|
only. Search results that include results from referrals might not be unique.</p>

<div class="notebody">Binary attributes, operational attributes, configuration attributes,
|
||
|
|
and the objectclass attribute cannot be designated as unique.</div>
|
||
|
|
<p>Not all attributes can be specified as unique. To determine if an attribute
|
||
|
|
can be specified as unique, use the ldapexop command:</p>
|
||
|
|
<ul>
|
||
|
|
<li>For attributes that can be unique: <tt class="xph">ldapexop -op getattributes -attrType
|

|
|
unique -matches true</tt></li>
|
||
|
|
<li>For attributes that cannot be unique: <tt class="xph">ldapexop -op getattributes
|
||
|
|
-attrType unique -matches false</tt></li></ul>
|
