<p>This function creates an authentication context to hold configuration and state relevant to krb5 functions for authenticating principals and protecting messages once authentication has occurred.</p>
<p>By default, flags for the context are set to enable the use of the replay cache ( <a class="reference internal" href="../macros/KRB5_AUTH_CONTEXT_DO_TIME.html#KRB5_AUTH_CONTEXT_DO_TIME" title="KRB5_AUTH_CONTEXT_DO_TIME"><code class="xref py py-data docutils literal"><span class="pre">KRB5_AUTH_CONTEXT_DO_TIME</span></code></a> ), but not sequence numbers. Use <a class="reference internal" href="krb5_auth_con_setflags.html#c.krb5_auth_con_setflags" title="krb5_auth_con_setflags"><code class="xref c c-func docutils literal"><span class="pre">krb5_auth_con_setflags()</span></code></a> to change the flags.</p>
<p>The allocated <em>auth_context</em> must be freed with <a class="reference internal" href="krb5_auth_con_free.html#c.krb5_auth_con_free" title="krb5_auth_con_free"><code class="xref c c-func docutils literal"><span class="pre">krb5_auth_con_free()</span></code></a> when it is no longer needed.</p>
