These interfaces are functional, but the 59interfaces are likely to change in incompatible ways from release to 60release. In some cases, it may be necessary to copy header files from 61the krb5 source tree to use an internal interface. Use these with 62care, and expect to need to update your modules for each new release 63of MIT krb5.</p> 64<section id="kerberos-database-interface-kdb"> 65<h2>Kerberos database interface (KDB)<a class="headerlink" href="#kerberos-database-interface-kdb" title="Permalink to this headline">¶</a></h2> 66<p>A KDB module implements a database back end for KDC principal and 67policy information, and can also control many aspects of KDC behavior. 68For a full description of the interface, see the header file 69<code class="docutils literal notranslate"><span class="pre"><kdb.h></span></code>.</p> 70<p>The KDB pluggable interface is often referred to as the DAL (Database 71Access Layer).</p> 72</section> 73<section id="authorization-data-interface-authdata"> 74<h2>Authorization data interface (authdata)<a class="headerlink" href="#authorization-data-interface-authdata" title="Permalink to this headline">¶</a></h2> 75<p>The authdata interface allows a module to provide (from the KDC) or 76consume (in application servers) authorization data of types beyond 77those handled by the core MIT krb5 code base.
