<h3>Summary</h3>
 | 
						||
 | 
						||
    <p>This module provides core authorization capabilities so that
 | 
						||
    authenticated users can be allowed or denied access to portions
 | 
						||
    of the web site. <code class="module"><a href="../mod/mod_authz_core.html">mod_authz_core</a></code> provides the 
 | 
						||
    functionality to register various authorization providers. It is
 | 
						||
    usually used in conjunction with an authentication
 | 
						||
    provider module such as <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code> and an 
 | 
						||
    authorization module such as <code class="module"><a href="../mod/mod_authz_user.html">mod_authz_user</a></code>. It
 | 
						||
    also allows for advanced logic to be applied to the 
 | 
						||
    authorization processing.</p>

<h2><a name="authzalias" id="authzalias">Creating Authorization Provider Aliases</a></h2>
 | 
						||
 | 
						||
    <p>Extended authorization providers can be created within the configuration
 | 
						||
    file and assigned an alias name.  The alias providers can then be referenced
 | 
						||
    through the <code class="directive"><a href="#require">Require</a></code> directive
 | 
						||
    in the same way as a base authorization provider.  Besides the ability to
 | 
						||
    create and alias an extended provider, it also allows the same extended
 | 
						||
    authorization provider to be reference by multiple locations.
 | 
						||
    </p>
 | 
						||
 | 
						||
    <h3><a name="example" id="example">Example</a></h3>
 | 
						||
        <p>The example below creates two different ldap authorization provider
 | 
						||
        aliases based on the ldap-group authorization provider.  This example
 | 
						||
        allows a single authorization location to check group membership within
 | 
						||
        multiple ldap hosts:

    <code>admins</code> group and the <code>Administrators</code> LDAP

    group and either belong to the <code>sales</code> group or

    have the LDAP <code>dept</code> attribute <code>sales</code>.

    Furthermore, in order to access the resource, the user must

    not belong to either the <code>temps</code> group or the

 | 
						||
 | 
						||
  <p><code class="module"><a href="../mod/mod_authz_core.html">mod_authz_core</a></code> provides some generic authorization
 | 
						||
  providers which can be used with the
 | 
						||
  <code class="directive"><a href="#require">Require</a></code> directive.</p>
 | 
						||
 | 
						||
  <h3><a name="reqenv" id="reqenv">Require env</a></h3>
 | 
						||
 | 
						||
    <p>The <code>env</code> provider allows access to the server
 | 
						||
    to be controlled based on the existence of an <a href="../env.html">environment variable</a>. When <code>Require 
 | 
						||
    env <var>env-variable</var></code> is specified, then the request is
 | 
						||
    allowed access if the environment variable <var>env-variable</var>
 | 
						||
    exists. The server provides the ability to set environment
 | 
						||
    variables in a flexible way based on characteristics of the client
 | 
						||
    request using the directives provided by
 | 
						||
    <code class="module"><a href="../mod/mod_setenvif.html">mod_setenvif</a></code>. Therefore, this directive can be
 | 
						||
    used to allow access based on such factors as the clients
 | 
						||
    <code>User-Agent</code> (browser type), <code>Referer</code>, or
 | 
						||
    other HTTP request header fields.</p>
 | 
						||
    
 | 
						||
    <div class="example"><h3>Example:</h3><p><code>
 | 
						||
      SetEnvIf User-Agent ^KnockKnock/2\.0 let_me_in<br />
 | 
						||
      <Directory /docroot><br />
 | 
						||
      <span class="indent">
 | 
						||
        Require env let_me_in<br />
 | 
						||
      </span>
 | 
						||
      </Directory>
 | 
						||
    </code></p></div>
 | 
						||
    
 | 
						||
    <p>In this case, browsers with a user-agent string beginning
 | 
						||
    with <code>KnockKnock/2.0</code> will be allowed access, and all
 | 
						||
    others will be denied.</p>
 |

 | 
						||
  
 | 
						||
 | 
						||
  <h3><a name="reqall" id="reqall">Require all</a></h3>
 | 
						||
 | 
						||
    <p>The <code>all</code> provider mimics the functionality the
 | 
						||
    was previously provided by the 'Allow from all' and 'Deny from all'
 | 
						||
    directives.  This provider can take one of two arguments which are 
 | 
						||
    'granted' or 'denied'.  The following examples will grant or deny 
 | 
						||
    access to all requests.</p>
 | 
						||
 | 
						||
    <div class="example"><p><code>
 | 
						||
    Require all granted<br />
 | 
						||
    </code></p></div>

    <div class="example"><p><code>

						||
    Require all denied<br />
 |

    </code></p></div>

						||
 | 
						||
  
 | 
						||
 | 
						||
  <h3><a name="reqmethod" id="reqmethod">Require method</a></h3>
 | 
						||
 | 
						||
    <p>The <code>method</code> provider allows to use the HTTP method in
 | 
						||
    authorization decisions. The GET and HEAD methods are treated as
 | 
						||
    equivalent. The TRACE method is not available to this provider,
 | 
						||
    use <code class="directive"><a href="../mod/core.html#traceenable">TraceEnable</a></code> instead.</p>
 | 
						||
 | 
						||
    <p>The following example will only allow GET, HEAD, POST, and OPTIONS
 | 
						||
    requests:</p>
 | 
						||
 | 
						||
    <div class="example"><p><code>
 | 
						||
        Require method GET POST OPTIONS<br />
 | 
						||
    </code></p></div>
 | 
						||
 | 
						||
    <p>The following example will allow GET, HEAD, POST, and OPTIONS
 | 
						||
    requests without authentication, and require a valid user for all other
 | 
						||
    methods:</p>
 | 
						||
 | 
						||
    <div class="example"><p><code>
 | 
						||
        <RequireAny><br />

         Require method GET POST OPTIONS<br />

  <h3><a name="reqexpr" id="reqexpr">Require expr</a></h3>
 |

 |

  <p>The <code>expr</code> provider allows to base authorization
 |

  decisions on arbitrary expressions.</p>
 | 
						||
 | 
						||
    <div class="example"><p><code>
 | 
						||
        Require expr %{TIME_HOUR} >= 9 & %{TIME_HOUR} <= 17 <br />

    and <code class="directive"><a href="../mod/mod_authz_groupfile.html#authgroupfile">AuthGroupFile</a></code> (to

    <div class="example"><p><code>

 |

    <p>Access controls which are applied in this way are effective for

    desired.</strong> If you wish to apply access controls only to

						||
    specific methods, while leaving other methods unprotected, then
 | 
						||
    place the <code class="directive">Require</code> statement into a
 | 
						||
    <code class="directive"><a href="../mod/core.html#limit"><Limit></a></code>
 |

    section.</p>

    <p>The result of the <code class="directive">Require</code> directive
 |

    may be negated through the use of the

    <code>not</code> option.  As with the other negated authorization
 | 
						||
    directive <code class="directive"><RequireNone></code>,
 | 
						||
    when the <code class="directive">Require</code> directive is negated it can
 | 
						||
    only fail or return a neutral result, and therefore may never
 | 
						||
    independently authorize a request.</p>
 | 
						||
 | 
						||
    <p>In the following example, all users in the <code>alpha</code>
 | 
						||
    and <code>beta</code> groups are authorized, except for those who
 | 
						||
    are also in the <code>reject</code> group.</p>
 | 
						||
 | 
						||
    <div class="example"><p><code>
 | 
						||
        <Directory /www/docs>
 | 
						||
        <span class="indent">
 | 
						||
            <RequireAll>

            <span class="indent">

    <p>When multiple <code class="directive">Require</code> directives are

    used in a single

    <a href="../sections.html#mergin">configuration section</a>

    and are not contained in another authorization directive like
 |

    <code class="directive"><a href="#requireall"><RequireAll></a></code>,

						||
    they are implicitly contained within a
 | 
						||
    <code class="directive"><a href="#requireany"><RequireAny></a></code>
 |

    directive.  Thus the first one to authorize a user authorizes the
 |

    entire request, and subsequent <code class="directive">Require</code> directives

    are ignored.</p>
