<p>When a superuser creates a <a href="/docs/en/2.7.0/reference-terminology#tenant">tenant</a>, that tenant is assigned an admin role.

<p>You can enable the authorization and assign the superusers in the broker (<a href="/docs/en/2.7.0/reference-configuration#broker"><code>conf/broker.conf</code></a>) configuration files.</p>
<pre><code class="hljs css language-properties"><span class="hljs-attr">authorizationEnabled</span>=<span class="hljs-string">true</span>
<span class="hljs-attr">superUserRoles</span>=<span class="hljs-string">my-super-user-1,my-super-user-2</span>
</code></pre>
<blockquote>
<p>A full list of parameters is available in the <code>conf/broker.conf</code> file.
You can also find the default values for those parameters in <a href="/docs/en/2.7.0/reference-configuration#broker">Broker Configuration</a>.</p>
</blockquote>
<p>Typically, you use superuser roles for administrators, clients as well as broker-to-broker authorization. When you use <a href="/docs/en/2.7.0/concepts-replication">geo-replication</a>, every broker needs to be able to publish to all the other topics of clusters.</p>
<p>You can also enable the authorization for the proxy in the proxy configuration file (<code>conf/proxy.conf</code>). Once you enable the authorization on the proxy, the proxy does an additional authorization check before forwarding the request to a broker.
If you enable authorization on the broker, the broker checks the authorization of the request when the broker receives the forwarded request.</p>

<p>By default, the broker treats the connection between a proxy and the broker as a normal user connection. The broker authenticates the user as the role configured in <code>proxy.conf</code>(see <a href="/docs/en/2.7.0/security-tls-authentication#enable-tls-authentication-on-proxies">&quot;Enable TLS Authentication on Proxies&quot;</a>). However, when the user connects to the cluster through a proxy, the user rarely requires the authentication. The user expects to be able to interact with the cluster as the role for which they have authenticated with the proxy.</p>
<p>Pulsar uses <em>Proxy roles</em> to enable the authentication. Proxy roles are specified in the broker configuration file, <a href="/docs/en/2.7.0/reference-configuration#broker"><code>conf/broker.conf</code></a>. If a client that is authenticated with a broker is one of its <code>proxyRoles</code>, all requests from that client must also carry information about the role of the client that is authenticated with the proxy. This information is called the <em>original principal</em>. If the <em>original principal</em> is absent, the client is not able to access anything.</p>
<p>You must authorize both the <em>proxy role</em> and the <em>original principal</em> to access a resource to ensure that the resource is accessible via the proxy. Administrators can take two approaches to authorize the <em>proxy role</em> and the <em>original principal</em>.</p>
<p>The more secure approach is to grant access to the proxy roles each time you grant access to a resource. For example, if you have a proxy role named <code>proxy1</code>, when the superuser creates a tenant, you should specify <code>proxy1</code> as one of the admin roles. When a role is granted permissions to produce or consume from a namespace, if that client wants to produce or consume through a proxy, you should also grant <code>proxy1</code> the same permissions.</p>
<p>Another approach is to make the proxy role a superuser. This allows the proxy to access all resources. The client still needs to authenticate with the proxy, and all requests made through the proxy have their role downgraded to the <em>original principal</em> of the authenticated client. However, if the proxy is compromised, a bad actor could get full access to your cluster.</p>
<p>You can specify the roles as proxy roles in <a href="/docs/en/2.7.0/reference-configuration#broker"><code>conf/broker.conf</code></a>.</p>

<p>This command creates a new tenant <code>my-tenant</code> that is allowed to use the clusters <code>us-west</code> and <code>us-east</code>.</p>
<p>A client that successfully identifies itself as having the role <code>my-admin-role</code> is allowed to perform all administrative tasks on this tenant.</p>
