<h1 id="kerberos-and-afs-authentication">Kerberos and AFS authentication<a class="headerlink" href="#kerberos-and-afs-authentication" title="Permanent link"></a></h1>
<p>Projects and users have their own areas in the central PSI AFS service. In order
to access to these areas, valid Kerberos and AFS tickets must be granted.</p>
<p>These tickets are automatically granted when accessing through SSH with
username and password. Alternatively, one can get a granting ticket with the <code>kinit</code> (Kerberos)
and <code>aklog</code> (AFS ticket, which needs to be run after <code>kinit</code>) commands.</p>
<p>Due to PSI security policies, the maximum lifetime of the ticket is 7 days, and the default
time is 10 hours. It means than one needs to constantly renew (<code>krenew</code> command) the existing
granting tickets, and their validity can not be extended longer than 7 days. At this point,
one needs to obtain new granting tickets.</p>
<h2 id="obtaining-granting-tickets-with-username-and-password">Obtaining granting tickets with username and password<a class="headerlink" href="#obtaining-granting-tickets-with-username-and-password" title="Permanent link"></a></h2>
<p>As already described above, the most common use case is to obtain Kerberos and AFS granting tickets
by introducing username and password:</p>
<ul>
<li>When login to Merlin through SSH protocol, if this is done with username + password authentication,
tickets for Kerberos and AFS will be automatically obtained.</li>
<li>When login to Merlin through NoMachine, no Kerberos and AFS are granted. Therefore, users need to
run <code>kinit</code> (to obtain a granting Kerberos ticket) followed by <code>aklog</code> (to obtain a granting AFS ticket).
See further details below.</li>
</ul>
<p>To manually obtain granting tickets, one has to:</p>
<ol>
<li>To obtain a granting Kerberos ticket, one needs to run <code>kinit $USER</code> and enter the PSI password.</li>

<p>Sometimes, obtaining granting tickets by using password authentication is not possible. An example are user Slurm jobs
requiring access to private areas in AFS. For that, there's the possibility to generate a <strong>keytab</strong> file.</p>
<p>Be aware that the <strong>keytab</strong> file must be <strong>private</strong>, <strong>fully protected</strong> by correct permissions and not shared with any
other users.</p>
<h3 id="creating-a-keytab-file">Creating a keytab file<a class="headerlink" href="#creating-a-keytab-file" title="Permanent link"></a></h3>
<p>For generating a <strong>keytab</strong>, one has to:</p>
<ol>
<li>Create a private directory for storing the Kerberos <strong>keytab</strong> file</li>
</ol>
<div class="language-bash highlight"><span class="filename">Bash</span><pre><span></span><code><span id="__span-4-1"><a id="__codelineno-4-1" name="__codelineno-4-1" href="#__codelineno-4-1"></a>mkdir<span class="w"> </span>-p<span class="w"> </span>~/.k5

<li>In the <code>ktutil</code> console, one has to generate a <strong>keytab</strong> file as follows:</li>
</ol>
<div class="language-bash highlight"><span class="filename">Bash</span><pre><span></span><code><span id="__span-6-1"><a id="__codelineno-6-1" name="__codelineno-6-1" href="#__codelineno-6-1"></a><span class="c1"># Replace $USER by your username</span>

<p>Please note:
* That you will need to add your password once. This step is required for generating the <strong>keytab</strong> file.
* <code>ktutil</code>does <strong>not</strong> report an error if you enter a wrong password! You can test with the <code>kinit</code> command documented below. If <code>kinit</code> fails with an error message like "pre-authentication failed", this is usually due to a wrong password/key in the keytab file. In this case <strong>you have to remove the keytab file</strong> and re-run the <code>ktutil</code> command. See "Updating the keytab file" in the section below.</p>

<p>Some jobs may require to access private areas in AFS. For that, having a valid <a href="./#creating-a-keytab-file"><strong>keytab</strong></a> file is required.
Then, from inside the batch script one can obtain granting tickets for Kerberos and AFS, which can be used for accessing AFS private areas.</p>
<p>The steps should be the following:</p>
<ul>
<li>Setup <code>KRB5CCNAME</code>, which can be used to specify the location of the Kerberos5 credentials (ticket) cache. In general it should point to a shared area
(<code>$HOME/.k5</code> is a good location), and is strongly recommended to generate an independent Kerberos5 credential cache (it is, creating a new credential cache per Slurm job):</li>

<p>Some users may need/prefer to run with a shared cache file. For doing that, one needs to
setup <code>KRB5CCNAME</code> from the <strong>login node</strong> session, before submitting the job.</p>
<div class="language-bash highlight"><span class="filename">Bash</span><pre><span></span><code><span id="__span-16-1"><a id="__codelineno-16-1" name="__codelineno-16-1" href="#__codelineno-16-1"></a><span class="nb">export</span><span class="w"> </span><span class="nv">KRB5CCNAME</span><span class="o">=</span><span class="s2">"</span><span class="k">$(</span>mktemp<span class="w"> </span><span class="s2">"</span><span class="nv">$HOME</span><span class="s2">/.k5/krb5cc_XXXXXX"</span><span class="k">)</span><span class="s2">"</span>
</span></code></pre></div>
<p>Then, you can run one or multiple jobs scripts (or parallel job with <code>srun</code>). <code>KRB5CCNAME</code> will be propagated to the
job script or to the parallel job, therefore a single credential cache will be shared amongst different Slurm runs.</p>
