For a detailed description of the kadm5_hook interface, see the header file <tt class="docutils literal"><span class="pre"><krb5/kadm5_hook_plugin.h></span></tt>.</p> <p>The kadm5_hook interface has five primary methods: <strong>chpass</strong>, <strong>create</strong>, <strong>modify</strong>, <strong>remove</strong>, and <strong>rename</strong>. (The <strong>rename</strong> method was introduced in release 1.14.) Each of these methods is called twice when the corresponding administrative action takes place, once before the action is committed and once afterwards. A module can prevent the action from taking place by returning an error code during the pre-commit stage.</p> <p>A module can create and destroy per-process state objects by implementing the <strong>init</strong> and <strong>fini</strong> methods. State objects have the type kadm5_hook_modinfo, which is an abstract pointer type. A module should typically cast this to an internal type for the state object.</p> <p>Because the kadm5_hook interface is tied closely to the kadmin interface (which is explicitly unstable), it may not remain as stable across versions as other public pluggable interfaces.</p> </div> </div> </div> </div> </div> <div class="sidebar"> <h2>On this page</h2> <ul> <li><a class="reference internal" href="#">KADM5 hook interface (kadm5_hook)</a></li> </ul> <br/> <h2>Table of contents</h2> <ul class="current"> <li class="toctree-l1"><a class="reference internal" href="../user/index.html">For users</a></li> <li class="toctree-l1"><a class="reference internal" href="../admin/index.html">For administrators</a></li> <li class="toctree-l1"><a class="reference internal" href="../appdev/index.html">For application developers</a></li> <li class="toctree-l1 current"><a class="reference internal" href="index.html">For plugin module developers</a><ul class="current"> <li class="toctree-l2"><a class="reference internal" href="general.html">General plugin concepts</a></li> <li class="toctree-l2"><a class="reference internal" href="clpreauth.html">Client preauthentication interface (clpreauth)</a></li> <li class="toctree-l2"><a class="reference internal" href="kdcpreauth.html">KDC preauthentication interface (kdcpreauth)</a></li> <li class="toctree-l2"><a class="reference internal" href="ccselect.html">Credential cache selection interface (ccselect)</a></li> <li class="toctree-l2"><a class="reference internal" href="pwqual.html">Password quality interface (pwqual)</a></li> <li class="toctree-l2 current"><a class="current reference internal" href="">KADM5 hook interface (kadm5_hook)</a></li> <li class="toctree-l2"><a class="reference internal" href="hostrealm.html">Host-to-realm interface (hostrealm)</a></li> <li class="toctree-l2"><a class="reference internal" href="localauth.html">Local authorization interface (localauth)</a></li> <li class="toctree-l2"><a class="reference internal" href="locate.html">Server location interface (locate)</a></li> <li class="toctree-l2"><a class="reference internal" href="profile.html">Configuration interface (profile)</a></li> <li class="toctree-l2"><a class="reference internal" href="gssapi.html">GSSAPI mechanism interface</a></li> <li class="toctree-l2"><a class="reference internal" href="internal.html">Internal pluggable interfaces</a></li> <li class="toctree-l2"><a class="reference internal" href="certauth.html">PKINIT certificate authorization interface (certauth)</a></li> <li class="toctree-l2"><a class="reference internal" href="kdcpolicy.html">KDC policy interface (kdcpolicy)</a></li> </ul> </li> <li class="toctree-l1"><a class="reference internal" href="../build/index.html">Building Kerberos V5</a></li> <li class="toctree-l1"><a class="reference internal" href="../basic/index.html">Kerberos V5 concepts</a></li> <li class="toctree-l1"><a class="reference internal" href="../formats/index.html">Protocols and file formats</a></li> <li class="toctree-l1"><a class="reference internal" href="../mitK5features.html">MIT Kerberos features</a></li> <li class="toctree-l1"><a class="reference internal" href="../build_this.html">How to build this documentation from the source</a></li> <li class="toctree-l1"><a class="reference internal" href="../about.html">Contributing to the MIT Kerberos Documentation</a></li> <li class="toctree-l1"><a class="reference internal" href="../resources.html">Resources</a></li> </ul> <br/> <h4><a href="../index.html">Full Table of Contents</a></h4> <h4>Search</h4> <form class="search" action="../search.html" method="get"> <input type="text" name="q" size="18" /> <input type="submit" value="Go" /> <input type="hidden" name="check_keywords" value="yes" /> <input type="hidden" name="area" value="default" /> </form> </div> <div class="clearer"></div> </div> </div> <div class="footer-wrapper"> <div class="footer" > <div class="right" ><i>Release: 1.15.1</i><br /> © <a href="../copyright.html">Copyright</a> 1985-2017, MIT. </div> <div class="left"> <a href="../index.html" title="Full Table of Contents" >Contents</a> | <a href="pwqual.html" title="Password quality interface (pwqual)" >previous</a> | <a href="hostrealm.html" title="Host-to-realm interface (hostrealm)" >next</a> | <a href="../genindex.html" title="General Index" >index</a> | <a href="../search.html" title="Enter search criteria" >Search</a> | <a href="mailto:krb5-bugs@mit.edu?subject=Documentation__KADM5 hook interface (kadm5_hook)">feedback</a> </div> </div> </div> </body> </html>
