     64Once 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]]
     65`HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tracd\Parameters`
     66
     67Three (string) parameters are provided:
     68||!AppDirectory ||C:\Python26\ ||
     69||Application ||python.exe ||
     70||!AppParameters ||scripts\tracd-script.py -p 8080 ... ||
     71
     72Note 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.
     73(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.)

    7395== Using Authentication ==
    7496
    75 Using tracd with Apache .htpasswd files:
    76 
    77 To create a .htpasswd file using htpasswd:
    78 
    79 {{{
    80  $ htpasswd -c /path/to/env/.htpasswd username
    81 }}}
    82 then for additional users:
    83 {{{
    84  $ htpasswd /path/to/env/.htpasswd username2
    85 }}}
    86 then for starting the tracd (on windows skip the "=" after --basic-auth):
    87 {{{
    88 tracd -p 8080 --basic-auth=environmentname,/fullpath/environmentname/.htpasswd,/fullpath/environmentname /fullpath/environmentname
    89 }}}
    90 
    91  `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.
    92 
    93 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.)
    94 
    95   ''Support for Basic authentication was added in version 0.9.''
    96 
    97 The general format for using authentication is (replace `--auth` with `--basic-auth` if you want to use Basic auth):
    98 
     97Tracd 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.
     98
     99The general format for using authentication is:
    99100{{{
    100101 $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path
    101102}}}
    102 
    103103where:
    104 
    105104 * '''base_project_dir''': the base directory of the project specified as follows:
    106105   * when serving multiple projects: ''relative'' to the `project_path`
     
    111110 * '''project_path''': path of the project
    112111
     112 * **`--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.

    135 === Using a htpasswd password file ===
     136=== Basic Authorization: Using a htpasswd password file ===
    136137This section describes how to use `tracd` with Apache .htpasswd files.
    137138
     139  Note: It is necessary (at least with Python 2.6) to install the fcrypt package in order to
     140  decode some htpasswd formats.  Trac source code attempt an `import crypt` first, but there
     141  is no such package for Python 2.6. Only `SHA-1` passwords (since Trac 1.0) work without this module.
     142
    138143To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache):
    139 
    140144{{{
    141145 $ sudo htpasswd -c /path/to/env/.htpasswd username
     
    147151
    148152Then to start `tracd` run something like this:
    149 
    150153{{{
    151154 $ tracd -p 8080 --basic-auth="projectdirname,/fullpath/environmentname/.htpasswd,realmname" /fullpath/environmentname
     
    153156
    154157For example:
    155 
    156158{{{
    157159 $ tracd -p 8080 --basic-auth="testenv,/srv/tracenv/testenv/.htpasswd,My Test Env" /srv/tracenv/testenv
    158160}}}
    159 
    160161''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD).
    161162
    162 === Using a htdigest password file ===
     163=== Digest authentication: Using a htdigest password file ===
    163164
    164165If 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.
    165166
    166 Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error.
     167Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error.
    167168
    168169=== Generating Passwords Without Apache ===
    169170
    170 If you don't have Apache available, you can use this simple Python script to generate your passwords:
     171Basic 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.
     172
     173You can use this simple Python script to generate a '''digest''' password file:
    171174
    172175{{{
     
    202205}}}
    203206
    204 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):
     207Note: 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):
    205208
    206209{{{
     
    209212}}}
    210213
    211 
    212 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.)
    213 
    214 It is possible to use md5sum utility to generate digest-password file using such method:
    215 {{{
    216  $ printf "${user}:trac:${password}" | md5sum - >>user.htdigest
    217 }}}
    218 and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'.
     214==== Using `md5sum`
     215It is possible to use `md5sum` utility to generate digest-password file:
     216{{{
     217user=
     218realm=
     219password=
     220path_to_file=
     221echo ${user}:${realm}:$(printf "${user}:${realm}:${password}" | md5sum - | sed -e 's/\s\+-//') > ${path_to_file}

    237 === Using apache rewrite rules ===
    238 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.
     277=== Using tracd behind a proxy
     278
     279In some situations when you choose to use tracd behind Apache or another web server.
     280
     281In 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.
     282
     283If 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.
     284
     285See also [trac:TracOnWindowsIisAjp], [trac:TracNginxRecipe].
     286
     287=== Authentication for tracd behind a proxy
     288It is convenient to provide central external authentication to your tracd instances, instead of using {{{--basic-auth}}}. There is some discussion about this in #9206.
     289
     290Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap.
     291
     292First we bring tracd into Apache's location namespace.
     293
     294{{{
     295<Location /project/proxified>
     296        Require ldap-group cn=somegroup, ou=Groups,dc=domain.com
     297        Require ldap-user somespecificusertoo
     298        ProxyPass http://localhost:8101/project/proxified/
     299        # Turns out we don't really need complicated RewriteRules here at all
     300        RequestHeader set REMOTE_USER %{REMOTE_USER}s
     301</Location>
     302}}}
     303
     304Then 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:
     305{{{
     306#!python
     307from trac.core import *
     308from trac.config import BoolOption
     309from trac.web.api import IAuthenticator
     310
     311class MyRemoteUserAuthenticator(Component):
     312
     313    implements(IAuthenticator)
     314
     315    obey_remote_user_header = BoolOption('trac', 'obey_remote_user_header', 'false',
     316               """Whether the 'Remote-User:' HTTP header is to be trusted for user logins
     317                (''since ??.??').""")
     318
     319    def authenticate(self, req):
     320        if self.obey_remote_user_header and req.get_header('Remote-User'):
     321            return req.get_header('Remote-User')
     322        return None
     323
     324}}}
     325
     326Add this new parameter to your TracIni:
     327{{{
     328...
     329[trac]
     330...
     331obey_remote_user_header = true
     332...
     333}}}
     334
     335Run tracd:
     336{{{
     337tracd -p 8101 -r -s proxified --base-path=/project/proxified
     338}}}
     339
     340Note 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.
     341
     342Global config (e.g. `/srv/trac/conf/trac.ini`):
     343{{{
     344[components]
     345remote-user-auth.* = enabled
     346[inherit]
     347plugins_dir = /srv/trac/plugins
     348[trac]
     349obey_remote_user_header = true
     350}}}
     351
     352Environment config (e.g. `/srv/trac/envs/myenv`):
     353{{{
     354[inherit]
     355file = /srv/trac/conf/trac.ini
