+<span id="auth-indicator"></span><h1>Authentication indicators<a class="headerlink" href="#authentication-indicators" title="Permalink to this headline">¶</a></h1>

+<p>As of release 1.14, the KDC can be configured to annotate tickets if

+the client authenticated using a stronger preauthentication mechanism

+such as <a class="reference internal" href="pkinit.html#pkinit"><span class="std std-ref">PKINIT</span></a> or <a class="reference internal" href="otp.html#otp-preauth"><span class="std std-ref">OTP</span></a>. These

+annotations are called “authentication indicators.” Service

+principals can be configured to require particular authentication

+indicators in order to authenticate to that service. An

+authentication indicator value can be any string chosen by the KDC

+administrator; there are no pre-set values.</p>

+<p>To use authentication indicators with PKINIT or OTP, first configure

+the KDC to include an indicator when that preauthentication mechanism

+is used. For PKINIT, use the <strong>pkinit_indicator</strong> variable in

+<a class="reference internal" href="conf_files/kdc_conf.html#kdc-conf-5"><span class="std std-ref">kdc.conf</span></a>. For OTP, use the <strong>indicator</strong> variable in the

+token type definition, or specify the indicators in the <strong>otp</strong> user

+string as described in <a class="reference internal" href="otp.html#otp-preauth"><span class="std std-ref">OTP Preauthentication</span></a>.</p>

+<p>To require an indicator to be present in order to authenticate to a

+service principal, set the <strong>require_auth</strong> string attribute on the

+principal to the indicator value to be required. If you wish to allow

+one of several indicators to be accepted, you can specify multiple

+indicator values separated by spaces.</p>

+<p>For example, a realm could be configured to set the authentication

+indicator value “strong” when PKINIT is used to authenticate, using a

+setting in the <a class="reference internal" href="conf_files/kdc_conf.html#kdc-realms"><span class="std std-ref">[realms]</span></a> subsection:</p>

+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="n">pkinit_indicator</span> <span class="o">=</span> <span class="n">strong</span>

+</pre></div>

+</div>

+<p>A service principal could be configured to require the “strong”

+authentication indicator value:</p>

+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ kadmin setstr host/high.value.server require_auth strong

+Password for user/admin@KRBTEST.COM:

+</pre></div>

+</div>

+<p>A user who authenticates with PKINIT would be able to obtain a ticket

+for the service principal:</p>

+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ kinit -X X509_user_identity=FILE:/my/cert.pem,/my/key.pem user

+$ kvno host/high.value.server

+host/high.value.server@KRBTEST.COM: kvno = 1

+</pre></div>

+</div>

+<p>but a user who authenticates with a password would not:</p>

+<div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ kinit user

+Password for user@KRBTEST.COM:

+$ kvno host/high.value.server

+kvno: KDC policy rejects request while getting credentials for

+ host/high.value.server@KRBTEST.COM

+</pre></div>

+</div>

+<p>GSSAPI server applications can inspect authentication indicators

+through the <a class="reference internal" href="../appdev/gssapi.html#gssapi-authind-attr"><span class="std std-ref">auth-indicators</span></a> name

+attribute.</p>
