This type of authentication solution is typically\nseen on intranet sites, with single sign-on solutions such as IIS and\nIntegrated Windows Authentication or Apache and <a class=\"reference external\" href=\"https://httpd.apache.org/docs/current/mod/mod_authnz_ldap.html\">mod_authnz_ldap</a>, <a class=\"reference external\" href=\"https://www.apereo.org/projects/cas\">CAS</a>,\n<a class=\"reference external\" href=\"https://uit.stanford.edu/service/authentication\">WebAuth</a>, <a class=\"reference external\" href=\"https://sourceforge.net/projects/mod-auth-sspi\">mod_auth_sspi</a>, etc.</p>\n<p>When the web server takes care of authentication it typically provides the\nauthenticated user as <code class=\"docutils literal notranslate\">REMOTE_USER</code>. In Django, this value is made available\nin <a class=\"reference internal\" href=\"/pt-br/6.1/ref/request-response/#django.http.HttpRequest.META\" title=\"django.http.HttpRequest.META\"><code class=\"xref py py-attr docutils literal notranslate\">request.META</code></a> (as <code class=\"docutils literal notranslate\">REMOTE_USER</code> when\nsupplied as an environment variable, as in WSGI, or <code class=\"docutils literal notranslate\">HTTP_REMOTE_USER</code> when\nsupplied via an HTTP header, as in ASGI).
