| <p>Sometimes it’s helpful to set particular limits on what certain users can do beyond the normal security settings related to authorization and authentication. |
| For example, limiting how many connections a user can create or how many queues a user can create. |
| This chapter will explain how to configure such limits.</p> |

| <p>Here is an example of the XML used to set resource limits:</p> |
| </div> |
| <div class="listingblock"> |
| <div class="content"> |
| <pre class="rouge highlight nowrap"><code data-lang="xml"><span class="nt"><resource-limit-settings></span> |
| <span class="nt"><resource-limit-setting</span> <span class="na">match=</span><span class="s">"myUser"</span><span class="nt">></span> |
| <span class="nt"><max-connections></span>5<span class="nt"></max-connections></span> |
| <span class="nt"><max-queues></span>3<span class="nt"></max-queues></span> |
| <span class="nt"></resource-limit-setting></span> |
| <span class="nt"></resource-limit-settings></span></code></pre> |
| </div> |

| <div class="paragraph"> |
| <p>Unlike the <code>match</code> from <code>address-setting</code>, this <code>match</code> does not use any wild-card syntax. |
| It’s a simple 1:1 mapping of the limits to a <strong>user</strong>.</p> |
| </div> |
| <div class="dlist"> |
| <dl> |
| <dt class="hdlist1">max-connections</dt> |
| <dd> |
| <p>How many connections the matched user can make to the broker. |
| The default is -1 which means there is no limit.</p> |
| </dd> |
| <dt class="hdlist1">max-queues</dt> |
| <dd> |
| <p>How many queues the matched user can create. |
| The default is -1 which means there is no limit.</p> |
