+= Tracd
 
 Tracd is a lightweight standalone Trac web server.
 It can be used in a variety of situations, from a test or development server to a multiprocess setup behind another web server used as a load balancer.
 
-== Pros ==
-
- * Fewer dependencies: You don't need to install apache or any other web-server.
- * Fast: Should be almost as fast as the [wiki:TracModPython mod_python] version (and much faster than the [wiki:TracCgi CGI]), even more so since version 0.12 where the HTTP/1.1 version of the protocol is enabled by default
- * Automatic reloading: For development, Tracd can be used in ''auto_reload'' mode, which will automatically restart the server whenever you make a change to the code (in Trac itself or in a plugin).

+
+== Cons
 
  * Fewer features: Tracd implements a very simple web-server and is not as configurable or as scalable as Apache httpd.
- * No native HTTPS support: [http://www.rickk.com/sslwrap/ sslwrap] can be used instead,

-{{{

+{{{#!sh
  $ tracd --hostname=localhost -p 8080 /path/to/project

 With more than one project. (http://localhost:8080/project1/ and http://localhost:8080/project2/)
-{{{
+{{{#!sh
  $ tracd -p 8080 /path/to/project1 /path/to/project2
 }}}
 
-You can't have the last portion of the path identical between the projects since Trac uses that name to keep the URLs of the
-different projects unique. So if you use `/project1/path/to` and `/project2/path/to`, you will only see the second project.

 An alternative way to serve multiple projects is to specify a parent directory in which each subdirectory is a Trac project, using the `-e` option. The example above could be rewritten:
-{{{
+{{{#!sh
  $ tracd -p 8080 -e /path/to

+}}}
+
+== 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.
+
+{{{#!div style="border: 1pt dotted; margin: 1em"
+**Attention:** 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, or HFS+ on OSX).
+}}}
 
 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.
 
 The general format for using authentication is:
-{{{

  $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path

-=== Basic Authorization: Using a htpasswd password file ===
+=== Basic Authorization: Using a htpasswd password file
+
 This section describes how to use `tracd` with Apache .htpasswd files.
 
+'''Note''': On Windows It is necessary to install the [https://pypi.python.org/pypi/passlib passlib] package in order to decode some htpasswd formats. Only `SHA-1` passwords (since Trac 1.0) work without this module.
+
 To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
+{{{#!sh
+ $ sudo htpasswd -c /path/to/env/.htpasswd username
+}}}
+then for additional users:
+{{{#!sh
+ $ sudo htpasswd /path/to/env/.htpasswd username2
+}}}
+
+Then to start `tracd` run something like this:
+{{{#!sh
+ $ tracd -p 8080 --basic-auth="project,/fullpath/environmentname/.htpasswd,realmname" /path/to/project
+}}}
+
+For example:
+{{{#!sh
+ $ tracd -p 8080 --basic-auth="project,/srv/tracenv/testenv/.htpasswd,My Test Env" /path/to/project
+}}}
+
+'''Note:''' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
+
+=== Digest authentication: Using a htdigest password file
+
+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 [https://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.
+
+Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error.
+
+=== Generating Passwords Without Apache
+
+Basic Authorization can be accomplished via this [http://aspirine.org/htpasswd_en.html online HTTP Password generator] which also supports `SHA-1`.  Copy the generated password-hash line to the .htpasswd file on your system. Note that Windows Python lacks the "crypt" module that is the default hash type for htpasswd. Windows Python can grok MD5 password hashes just fine and you should use MD5.
+
+Trac also provides `htpasswd` and `htdigest` scripts in [https://trac.edgewall.org/browser/trunk/contrib contrib] (also available in the tar or zip archive):
+{{{#!sh
+$ ./contrib/htpasswd.py -cb htpasswd user1 user1
+$ ./contrib/htpasswd.py -b htpasswd user2 user2
+}}}
+
+{{{#!sh
+$ ./contrib/htdigest.py -cb htdigest trac user1 user1
+$ ./contrib/htdigest.py -b htdigest trac user2 user2
+}}}
+
+==== Using `md5sum`
+
+It is possible to use `md5sum` utility to generate digest-password file:
+{{{#!sh
+user=
+realm=
+password=
+path_to_file=
+echo ${user}:${realm}:$(printf "${user}:${realm}:${password}" | md5sum - | sed -e 's/\s\+-//') > ${path_to_file}
+}}}

+Here's the online help, as a reminder (`tracd -h` or `tracd --help`):
 {{{
- $ sudo htpasswd -c /path/to/env/.htpasswd username
-}}}
-then for additional users:
-{{{
- $ sudo htpasswd /path/to/env/.htpasswd username2
-}}}
-
-Then to start `tracd` run something like this:
-{{{
- $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname
-}}}

-You can use this simple Python script to generate a '''digest''' password file:
-
-{{{
-#!python
-from optparse import OptionParser
-# The md5 module is deprecated in Python 2.5
-try:
-    from hashlib import md5
-except ImportError:
-    from md5 import md5
-realm = 'trac'
-
-# build the options
-usage = "usage: %prog [options]"
-parser = OptionParser(usage=usage)
-parser.add_option("-u", "--username",action="store", dest="username", type = "string",
-                  help="the username for whom to generate a password")
-parser.add_option("-p", "--password",action="store", dest="password", type = "string",
-                  help="the password to use")
-parser.add_option("-r", "--realm",action="store", dest="realm", type = "string",
-                  help="the realm in which to create the digest")
-(options, args) = parser.parse_args()
-
-# check options
-if (options.username is None) or (options.password is None):
-   parser.error("You must supply both the username and password")
-if (options.realm is not None):
-   realm = options.realm
-   
-# Generate the string to enter into the htdigest file
-kd = lambda x: md5(':'.join(x)).hexdigest()
-print ':'.join((options.username, realm, kd([options.username, realm, options.password])))
-}}}
-
-Note: If you use the above script you must set the realm in the `--auth` argument to '''`trac`'''. Example usage (assuming you saved the script as trac-digest.py):
-
-{{{
- $ python trac-digest.py -u username -p password >> c:\digest.txt
- $ tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name
-}}}
-
-==== Using `md5sum`
-It is possible to use `md5sum` utility to generate digest-password file:
-{{{
- $ printf "${user}:trac:${password}" | md5sum - >>user.htdigest
-}}}
-and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'.

+=== Authentication for tracd behind a proxy
+
+It is convenient to provide central external authentication to your tracd instances, instead of using `--basic-auth`. See also [trac:#9206].
+
+Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.
+
+First we bring tracd into Apache's location namespace.
+
+{{{#!apache
+<Location /project/proxified>
+        Require ldap-group cn=somegroup, ou=Groups,dc=domain.com
+        Require ldap-user somespecificusertoo

+        # 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:
+{{{#!ini

+obey_remote_user_header = true
+...
+}}}
+
+Run tracd:
+{{{#!sh
+tracd -p 8101 -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_directory] and enable it in your global `trac.ini`.
+
+Global config (e.g. `/srv/trac/conf/trac.ini`):
