<div class="textblock"><p>Description of the krb5_aname_to_lname(3) plugin facility. </p>
<p>The krb5_aname_to_lname(3) function is pluggable. The plugin is named KRB5_PLUGIN_AN2LN ("an2ln"), with a single minor version, KRB5_PLUGIN_AN2LN_VERSION_0 (0).</p>
<p>The plugin for krb5_aname_to_lname(3) consists of a data symbol referencing a structure of type krb5plugin_an2ln_ftable, with four fields:</p>
<dl class="params"><dt>Parameters</dt><dd>
<table class="params">
<tr><td class="paramname">init</td><td>Plugin initialization function (see krb5-plugin(7))</td></tr>
<tr><td class="paramname">minor_version</td><td>The plugin minor version number (0)</td></tr>
<tr><td class="paramname">fini</td><td>Plugin finalization function</td></tr>
<tr><td class="paramname">an2ln</td><td>Plugin aname_to_lname function</td></tr>
</table>
</dd>
</dl>
<p>The an2ln field is the plugin entry point that performs the traditional aname_to_lname operation however the plugin desires. It is invoked in no particular order relative to other an2ln plugins, but it has a 'rule' argument that indicates which plugin is intended to act on the rule. The plugin an2ln function must return KRB5_PLUGIN_NO_HANDLE if the rule is not applicable to it.</p>
<p>The plugin an2ln function has the following arguments, in this order:</p>
<ol type="1">
<li>plug_ctx, the context value output by the plugin's init function</li>
<li>context, a krb5_context</li>
<li>rule, the aname_to_lname rule being evaluated (from krb5.conf(5))</li>
<li>aname, the krb5_principal to be mapped to an lname</li>
<li>set_res_f, a function the plugin must call to set its result</li>
<li>set_res_ctx, the first argument to set_res_f (the second is the result lname string) </li>
</ol>
</div><hr/>The documentation for this struct was generated from the following file:<ul>
<li>/Volumes/gitvol/viktor/heimdal/lib/krb5/an2ln_plugin.h</li>
</ul>
