 == Using Authentication ==
+
+Tracd allows you to run Trac without the need for Apache, but you can take advantage of Apache's password tools (htpasswd and htdigest) to easily create a password file in the proper format for tracd to use in authentication. (It is also possible to create the password file without htpasswd or htdigest; see below for alternatives)
+
+Make sure you place the generated password files on a filesystem which supports sub-second timestamps, as Trac will monitor their modified time and changes happening on a filesystem with too coarse-grained timestamp resolution (like `ext2` or `ext3` on Linux) may go undetected.
 
 Tracd provides support for both Basic and Digest authentication. Digest is considered more secure. The examples below use Digest; to use Basic authentication, replace `--auth` with `--basic-auth` in the command line.

 This section describes how to use `tracd` with Apache .htpasswd files.

 If you have Apache available, you can use the htdigest command to generate the password file. Type 'htdigest' to get some usage instructions, or read [http://httpd.apache.org/docs/2.0/programs/htdigest.html this page] from the Apache manual to get precise instructions.  You'll be prompted for a password to enter for each user that you create.  For the name of the password file, you can use whatever you like, but if you use something like `users.htdigest` it will remind you what the file contains. As a suggestion, put it in your <projectname>/conf folder along with the [TracIni trac.ini] file.

+=== Authentication for tracd behind a proxy
+It is convenient to provide central external authentication to your tracd instances, instead of using {{{--basic-auth}}}. There is some discussion about this in #9206.
+
+Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.
+
+First we bring tracd into Apache's location namespace.
+
+{{{
+<Location /project/proxified>
+        Require ldap-group cn=somegroup, ou=Groups,dc=domain.com
+        Require ldap-user somespecificusertoo
+        ProxyPass http://localhost:8101/project/proxified/
+        # Turns out we don't really need complicated RewriteRules here at all
+        RequestHeader set REMOTE_USER %{REMOTE_USER}s
+</Location>
+}}}
+
+Then we need a single file plugin to recognize HTTP_REMOTE_USER header as valid authentication source. HTTP headers like '''HTTP_FOO_BAR''' will get converted to '''Foo-Bar''' during processing. Name it something like '''remote-user-auth.py''' and drop it into '''proxified/plugins''' directory:
+{{{
+#!python
+from trac.core import *
+from trac.config import BoolOption
+from trac.web.api import IAuthenticator
+
+class MyRemoteUserAuthenticator(Component):
+
+    implements(IAuthenticator)
+
+    obey_remote_user_header = BoolOption('trac', 'obey_remote_user_header', 'false', 
+               """Whether the 'Remote-User:' HTTP header is to be trusted for user logins 
+                (''since ??.??').""") 
+
+    def authenticate(self, req):
+        if self.obey_remote_user_header and req.get_header('Remote-User'): 
+            return req.get_header('Remote-User') 
+        return None
+
+}}}
+
+Add this new parameter to your TracIni:
+{{{
+...
+[trac]
+...
+obey_remote_user_header = true
+...
+}}}
+
+Run tracd:
+{{{
+tracd -p 8101 -r -s proxified --base-path=/project/proxified
+}}}
+
+Note that if you want to install this plugin for all projects, you have to put it in your [TracPlugins#Plugindiscovery global plugins_dir] and enable it in your global trac.ini.
+
+Global config (e.g. `/srv/trac/conf/trac.ini`):
+{{{
+[components]
+remote-user-auth.* = enabled
+[inherit]
+plugins_dir = /srv/trac/plugins
+[trac]
+obey_remote_user_header = true
+}}}
+
+Environment config (e.g. `/srv/trac/envs/myenv`):
+{{{
+[inherit]
+file = /srv/trac/conf/trac.ini
+}}}
