 == Using Authentication ==
+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.)
+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)
+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`
 …
  * '''realm''': the realm name (can be anything)
  * '''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
+ * **`--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.

 === 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 some htpasswd formats.  Trac source code attempt an `import crypt` first, but there
+  is no such package for Python 2.6. 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):
 {{{
  $ 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.
 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 ===
+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://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.
+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:
+{{{
+ $ 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 `md5sum`
+It is possible to use `md5sum` utility to generate digest-password file:
+{{{
+user=
+realm=
+password=
+path_to_file=
+echo ${user}:${realm}:$(printf "${user}:${realm}:${password}" | md5sum - | sed -e 's/\s\+-//') > ${path_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}}}. 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
+}}}
