 The spacing here is important.

+Once the service is installed, it might be simpler to run the Registry Editor rather than use the `reg add` command documented above.  Navigate to:[[BR]]
+`HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tracd\Parameters`
+Three (string) parameters are provided:
+||!AppDirectory ||C:\Python26\ ||
+||Application ||python.exe ||
+||!AppParameters ||scripts\tracd-script.py -p 8080 ... ||
+Note that, if the !AppDirectory is set as above, the paths of the executable ''and'' of the script name and parameter values are relative to the directory.  This makes updating Python a little simpler because the change can be limited, here, to a single point.
+(This is true for the path to the .htpasswd file, as well, despite the documentation calling out the /full/path/to/htpasswd; however, you may not wish to store that file under the Python directory.)

 For Windows 7 User, srvany.exe may not be an option, so you can use [http://www.google.com/search?q=winserv.exe WINSERV] utility and run:

+{{{
+$ cygrunsrv --install tracd --path /cygdrive/c/Python27/Scripts/tracd.exe --args '--port 8000 --env-parent-dir E:\IssueTrackers\Trac\Projects'
+$ net start tracd

 == Using Authentication ==
+Using tracd with Apache .htpasswd files:
+To create a .htpasswd file using htpasswd:
+{{{
+ $ htpasswd -c /path/to/env/.htpasswd username
+}}}
+then for additional users:
+{{{
+ $ htpasswd /path/to/env/.htpasswd username2
+}}}
+then for starting the tracd (on windows skip the "=" after --basic-auth):
+{{{
+tracd -p 8080 --basic-auth=environmentname,/fullpath/environmentname/.htpasswd,/fullpath/environmentname /fullpath/environmentname
+}}}
+ `environmentname` is the directory name of the Trac project folder, as opposed to `/fullpath/environmentname` which is the full path to the Trac project folder. See below for another example.
+Tracd provides support for both Basic and Digest authentication. The default is to use Digest; to use Basic authentication, replace `--auth` with `--basic-auth` in the examples below. (You must still specify a dialogic "realm", which can be an empty string by trailing the BASICAUTH with a comma.)
+  ''Support for Basic authentication was added in version 0.9.''
+The general format for using authentication is (replace `--auth` with `--basic-auth` if you want to use Basic auth):
+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
 }}}
 where:
  * '''base_project_dir''': the base directory of the project specified as follows:
    * when serving multiple projects: ''relative'' to the `project_path`
 …
  * '''project_path''': path of the project
+ * **`--auth`** in the above means use Digest authentication, replace `--auth` with `--basic-auth` if you want to use Basic auth.  Although Basic authentication does not require a "realm", the command parser does, so the second comma is required, followed directly by the closing quote for an empty realm name.
 Examples:

 === Using a htpasswd password file ===
+=== Basic Authorization: Using a htpasswd password file ===
 This section describes how to use `tracd` with Apache .htpasswd files.
+  Note: It is necessary (at least with Python 2.6) to install the fcrypt package in order to
+  decode the htpasswd format.  Trac source code attempt an `import crypt` first, but there
+  is no such package for Python 2.6.
 To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
 {{{
  $ sudo htpasswd -c /path/to/env/.htpasswd username
 …
 Then to start `tracd` run something like this:
 {{{
  $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname
 …
 For example:
 {{{
  $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv
 }}}
 ''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
 === Using a htdigest password file ===
+=== 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 [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.
 …
 === Generating Passwords Without Apache ===
+If you don't have Apache available, you can use this simple Python script to generate your passwords:
+Basic Authorization can be accomplished via this [http://www.4webhelp.net/us/password.php online HTTP Password generator].  Copy the generated password-hash line to the .htpasswd file on your system.
+You can use this simple Python script to generate a '''digest''' password file:
 {{{
 …
 }}}
 Note: If you use the above script you must use the --auth option to tracd, not --basic-auth, and you must set the realm in the --auth value to 'trac' (without the quotes). Example usage (assuming you saved the script as trac-digest.py):
+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):
 {{{
 …
 }}}
+Note: If you would like to use --basic-auth you need to use htpasswd tool from apache server to generate .htpasswd file. The remaining part is similar but make sure to use empty realm (i.e. coma after path). Make sure to use -m option for it.  If you do not have Apache, [trac:source:/tags/trac-0.11/contrib/htpasswd.py htpasswd.py] may help.  (Note that it requires a `crypt` or `fcrypt` module; see the source comments for details.)
+It is possible to use md5sum utility to generate digest-password file using such method:
+==== 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'.

+=== Using apache rewrite rules ===
+In some situations when you choose to use tracd behind apache, you might experience issues with redirects, like being redirected to URLs with the wrong host or protocol. In this case (and only in this case), setting the `[trac] use_base_url_for_redirect` to `true` can help, as this will force Trac to use the value of `[trac] base_url` for doing the redirects.
+=== Using tracd behind a proxy
+In some situations when you choose to use tracd behind Apache or another web server.
+In this situation, you might experience issues with redirects, like being redirected to URLs with the wrong host or protocol. In this case (and only in this case), setting the `[trac] use_base_url_for_redirect` to `true` can help, as this will force Trac to use the value of `[trac] base_url` for doing the redirects.
+If you're using the AJP protocol to connect with `tracd` (which is possible if you have flup installed), then you might experience problems with double quoting. Consider adding the `--unquote` parameter.
+See also [trac:TracOnWindowsIisAjp], [trac:TracNginxRecipe].
+=== 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
+}}}
