<faq id="remove-oper-attr">
<question>How do I remove an operational attribute using <tt>context.removeAttributeValue()</tt>?</question>
<answer>
<p>
The DirContextAdapter will only read the visible attributes per default. This is because the
operational attributes will only be returned by the server if explicitly asked for, and there
is no way for Spring LDAP to know what attributes to ask for. This means that the DirContextAdapter
will not be populated with the operational attributes, and hence the <tt>removeAttributeValue</tt>
will not have any effect (since from the DirContextAdapter's point of view, it wasn't there in the
first place).
</p>
<p>
There are basically two ways to do this:
</p>
<ol>
<li>Use a search or lookup method that takes the attribute names as argument, like
<tt>LdapTemplate#lookup(Name, String[], ContextMapper)</tt>. Use a ContextMapper
implementation that just returns the supplied DirContextAdapter in <tt>mapFromContext()</tt>.
</li>
<li>Use <tt>LdapTemplate#modifyAttributes(Name, ModificationItem[])</tt> directly, manually
building the ModificationItem array.
</li>
</ol>
