| | 90 | $ net start tracd |
| | 91 | }}} |
| | 92 | |
| | 93 | == Using Authentication |
| | 94 | |
| | 95 | 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) |
| | 96 | |
| | 97 | {{{#!div style="border: 1pt dotted; margin: 1em" |
| | 98 | **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). |
| | 99 | }}} |
| | 100 | |
| | 101 | 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. |
| | 102 | |
| | 103 | The general format for using authentication is: |
| | 104 | {{{#!sh |
| | 105 | $ tracd -p port --auth="base_project_dir,password_file_path,realm" project_path |
| | 106 | }}} |
| | 107 | where: |
| | 108 | * '''base_project_dir''': the base directory of the project specified as follows: |
| | 109 | * when serving multiple projects: ''relative'' to the `project_path` |
| | 110 | * when serving only a single project (`-s`): the name of the project directory |
| | 111 | Don't use an absolute path here as this won't work. ''Note:'' This parameter is case-sensitive even for environments on Windows. |
| | 112 | * '''password_file_path''': path to the password file |
| | 113 | * '''realm''': the realm name (can be anything) |
| | 114 | * '''project_path''': path of the project |
| | 115 | |
| | 116 | * **`--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. |
| | 117 | |
| | 118 | Examples: |
| | 119 | |
| | 120 | {{{#!sh |
| | 121 | $ tracd -p 8080 \ |
| | 122 | --auth="project1,/path/to/passwordfile,mycompany.com" /path/to/project1 |
| | 123 | }}} |
| | 124 | |
| | 125 | Of course, the password file can be be shared so that it is used for more than one project: |
| | 126 | {{{#!sh |
| | 127 | $ tracd -p 8080 \ |
| | 128 | --auth="project1,/path/to/passwordfile,mycompany.com" \ |
| | 129 | --auth="project2,/path/to/passwordfile,mycompany.com" \ |
| | 130 | /path/to/project1 /path/to/project2 |
| | 131 | }}} |
| | 132 | |
| | 133 | Another way to share the password file is to specify "*" for the project name: |
| | 134 | {{{#!sh |
| | 135 | $ tracd -p 8080 \ |
| | 136 | --auth="*,/path/to/users.htdigest,mycompany.com" \ |
| | 137 | /path/to/project1 /path/to/project2 |
| | 138 | }}} |
| | 139 | |
| | 140 | === Basic Authorization: Using a htpasswd password file |
| | 141 | This section describes how to use `tracd` with Apache .htpasswd files. |
| | 142 | |
| | 143 | Note: On Windows It is necessary to install the fcrypt package in order to |
| | 144 | decode some htpasswd formats. Only `SHA-1` passwords (since Trac 1.0) work |
| | 145 | without this module. |
| | 146 | |
| | 147 | To create a .htpasswd file use Apache's `htpasswd` command (see [#GeneratingPasswordsWithoutApache below] for a method to create these files without using Apache): |
| | 148 | {{{#!sh |
| | 149 | $ sudo htpasswd -c /path/to/env/.htpasswd username |
| | 150 | }}} |
| | 151 | then for additional users: |
| | 152 | {{{#!sh |
| | 153 | $ sudo htpasswd /path/to/env/.htpasswd username2 |
| | 154 | }}} |
| | 155 | |
| | 156 | Then to start `tracd` run something like this: |
| | 157 | {{{#!sh |
| | 158 | $ tracd -p 8080 --basic-auth="project,/fullpath/environmentname/.htpasswd,realmname" /path/to/project |
| | 159 | }}} |
| | 160 | |
| | 161 | For example: |
| | 162 | {{{#!sh |
| | 163 | $ tracd -p 8080 --basic-auth="project,/srv/tracenv/testenv/.htpasswd,My Test Env" /path/to/project |
| | 164 | }}} |
| | 165 | ''Note:'' You might need to pass "-m" as a parameter to htpasswd on some platforms (OpenBSD). |
| | 166 | |
| | 167 | === Digest authentication: Using a htdigest password file |
| | 168 | |
| | 169 | 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. |
| | 170 | |
| | 171 | Note that you can start tracd without the `--auth` argument, but if you click on the ''Login'' link you will get an error. |
| | 172 | |
| | 173 | === Generating Passwords Without Apache |
| | 174 | |
| | 175 | 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. |
| | 176 | |
| | 177 | Trac also provides `htpasswd` and `htdigest` scripts in `contrib`: |
| | 178 | {{{#!sh |
| | 179 | $ ./contrib/htpasswd.py -cb htpasswd user1 user1 |
| | 180 | $ ./contrib/htpasswd.py -b htpasswd user2 user2 |
| | 181 | }}} |
| | 182 | |
| | 183 | {{{#!sh |
| | 184 | $ ./contrib/htdigest.py -cb htdigest trac user1 user1 |
| | 185 | $ ./contrib/htdigest.py -b htdigest trac user2 user2 |
| | 186 | }}} |
| | 187 | |
| | 188 | ==== Using `md5sum` |
| | 189 | It is possible to use `md5sum` utility to generate digest-password file: |
| | 190 | {{{#!sh |
| | 191 | user= |
| | 192 | realm= |
| | 193 | password= |
| | 194 | path_to_file= |
| | 195 | echo ${user}:${realm}:$(printf "${user}:${realm}:${password}" | md5sum - | sed -e 's/\s\+-//') > ${path_to_file} |
| | 196 | }}} |
| | 197 | |
| | 198 | == Reference |
| | 199 | |
| | 200 | Here's the online help, as a reminder (`tracd --help`): |
| 69 | | sc config tracd start= auto |
| 70 | | }}} |
| 71 | | |
| 72 | | The spacing here is important. |
| 73 | | |
| 74 | | == Using Authentication == |
| 75 | | |
| 76 | | Using tracd with Apache .htpasswd files: |
| 77 | | |
| 78 | | To create a .htpasswd file using htpasswd: |
| 79 | | |
| 80 | | {{{ |
| 81 | | sudo htpasswd -c /path/to/env/.htpasswd username |
| 82 | | }}} |
| 83 | | then for additional users: |
| 84 | | {{{ |
| 85 | | sudo htpasswd /path/to/env/.htpasswd username2 |
| 86 | | }}} |
| 87 | | then for starting the tracd: |
| 88 | | {{{ |
| 89 | | tracd -p 8080 --basic-auth=environmentname,/fullpath/environmentname/.htpasswd,/fullpath/environmentname /fullpath/environmentname |
| 90 | | }}} |
| 91 | | |
| 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: |
| 98 | | |
| 99 | | {{{ |
| 100 | | $ tracd -p port --auth=base_project_dir,password_file_path,realm project_path |
| 101 | | }}} |
| 102 | | |
| 103 | | where: |
| 104 | | |
| 105 | | * '''base_project_dir''' is the base directory of the project; note: this doesn't refer to the project name, and it is case-sensitive even for windows environments |
| 106 | | * '''password_file_path''' path of the password file |
| 107 | | * '''realm''' realm |
| 108 | | * '''project_path''' path of the project |
| 109 | | |
| 110 | | Example: |
| 111 | | |
| 112 | | {{{ |
| 113 | | $ tracd -p 8080 \ |
| 114 | | --auth=project1,/path/to/users.htdigest,mycompany.com /path/to/project1 |
| 115 | | }}} |
| 116 | | Of course, the digest file can be be shared so that it is used for more than one project: |
| 117 | | {{{ |
| 118 | | $ tracd -p 8080 \ |
| 119 | | --auth=project1,/path/to/users.htdigest,mycompany.com \ |
| 120 | | --auth=project2,/path/to/users.htdigest,mycompany.com \ |
| 121 | | /path/to/project1 /path/to/project2 |
| 122 | | }}} |
| 123 | | |
| 124 | | Another way to share the digest file is to specify "*" |
| 125 | | for the project name: |
| 126 | | {{{ |
| 127 | | $ tracd -p 8080 \ |
| 128 | | --auth="*",/path/to/users.htdigest,mycompany.com \ |
| 129 | | /path/to/project1 /path/to/project2 |
| 130 | | }}} |
| 131 | | If using the `-s` parameter for serving a Trac environment from the root of a domain, one must use `*` for the project name |
| 132 | | |
| 133 | | == How to set up an htdigest password file == |
| 134 | | |
| 135 | | 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. |
| 136 | | |
| 137 | | Note that you can start tracd without the --auth argument, but if you click on the ''Login'' link you will get an error. |
| 138 | | |
| 139 | | == Generating Passwords Without Apache == |
| 140 | | |
| 141 | | If you don't have Apache available, you can use this simple Python script to generate your passwords: |
| 142 | | |
| 143 | | {{{ |
| 144 | | #!python |
| 145 | | from optparse import OptionParser |
| 146 | | # The md5 module is deprecated in Python 2.5 |
| 147 | | try: |
| 148 | | from hashlib import md5 |
| 149 | | except ImportError: |
| 150 | | from md5 import md5 |
| 151 | | realm = 'trac' |
| 152 | | |
| 153 | | # build the options |
| 154 | | usage = "usage: %prog [options]" |
| 155 | | parser = OptionParser(usage=usage) |
| 156 | | parser.add_option("-u", "--username",action="store", dest="username", type = "string", |
| 157 | | help="the username for whom to generate a password") |
| 158 | | parser.add_option("-p", "--password",action="store", dest="password", type = "string", |
| 159 | | help="the password to use") |
| 160 | | parser.add_option("-r", "--realm",action="store", dest="realm", type = "string", |
| 161 | | help="the realm in which to create the digest") |
| 162 | | (options, args) = parser.parse_args() |
| 163 | | |
| 164 | | # check options |
| 165 | | if (options.username is None) or (options.password is None): |
| 166 | | parser.error("You must supply both the username and password") |
| 167 | | if (options.realm is not None): |
| 168 | | realm = options.realm |
| 169 | | |
| 170 | | # Generate the string to enter into the htdigest file |
| 171 | | kd = lambda x: md5(':'.join(x)).hexdigest() |
| 172 | | print ':'.join((options.username, realm, kd([options.username, realm, options.password]))) |
| 173 | | }}} |
| 174 | | |
| 175 | | 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): |
| 176 | | |
| 177 | | {{{ |
| 178 | | python trac-digest.py -u username -p password >> c:\digest.txt |
| 179 | | tracd --port 8000 --auth=proj_name,c:\digest.txt,trac c:\path\to\proj_name |
| 180 | | }}} |
| 181 | | |
| 182 | | 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). When using on Windows make sure to use -m option for it (did not tested it on *nix, so not sure if that is the case there). If you do not have Apache, [trac:source:/tags/trac-0.11b2/contrib/htpasswd.py htpasswd.py] may help. (Note that it requires a `crypt` or `fcrypt` module; see the source comments for details.) |
| 183 | | |
| 184 | | It is possible to use md5sum utility to generate digest-password file using such method: |
| 185 | | {{{ |
| 186 | | $ printf "${user}:trac:${password}" | md5sum - >>user.htdigest |
| 187 | | }}} |
| 188 | | and manually delete " -" from the end and add "${user}:trac:" to the start of line from 'to-file'. |
| 189 | | |
| 190 | | == Tips == |
| 191 | | |
| 192 | | === Serving static content === |
| 193 | | |
| 194 | | If `tracd` is the only webserver used for the project, |

| | 229 | --user=USER the user to run as |
| | 230 | }}} |
| | 231 | |
| | 232 | Use the -d option so that tracd doesn't hang if you close the terminal window where tracd was started. |
| | 233 | |
| | 234 | == Tips |
| | 235 | |
| | 236 | === Serving static content |
| | 237 | |
| | 238 | If `tracd` is the only web server used for the project, |
| 203 | | which in turn can be written using the relative link syntax |
| 204 | | in the Wiki: `[/<project_name>/chrome/site/software-0.1.tar.gz]` |
| 205 | | |
| 206 | | The development version of Trac supports a new `htdocs:` TracLinks |
| 207 | | syntax for the above. With this, the example link above can be written simply |
| 208 | | `htdocs:software-0.1.tar.gz`. |
| 209 | | |
| 210 | | === Using apache rewrite rules === |
| 211 | | 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. |
| 212 | | |
| 213 | | === Serving a different base path than / === |
| | 247 | which in turn can be written as `htdocs:software-0.1.tar.gz` (TracLinks syntax) or `[/<project_name>/chrome/site/software-0.1.tar.gz]` (relative link syntax). |
| | 248 | |
| | 249 | === Using tracd behind a proxy |
| | 250 | |
| | 251 | In some situations when you choose to use tracd behind Apache or another web server. |
| | 252 | |
| | 253 | 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. |
| | 254 | |
| | 255 | 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. |
| | 256 | |
| | 257 | See also [trac:TracOnWindowsIisAjp], [trac:TracNginxRecipe]. |
| | 258 | |
| | 259 | === Authentication for tracd behind a proxy |
| | 260 | It is convenient to provide central external authentication to your tracd instances, instead of using `--basic-auth`. There is some discussion about this in [trac:#9206]. |
| | 261 | |
| | 262 | Below is example configuration based on Apache 2.2, mod_proxy, mod_authnz_ldap. |
| | 263 | |
| | 264 | First we bring tracd into Apache's location namespace. |
| | 265 | |
| | 266 | {{{#!apache |
| | 267 | <Location /project/proxified> |
| | 268 | Require ldap-group cn=somegroup, ou=Groups,dc=domain.com |
| | 269 | Require ldap-user somespecificusertoo |
| | 270 | ProxyPass http://localhost:8101/project/proxified/ |
| | 271 | # Turns out we don't really need complicated RewriteRules here at all |
| | 272 | RequestHeader set REMOTE_USER %{REMOTE_USER}s |
| | 273 | </Location> |
| | 274 | }}} |
| | 275 | |
| | 276 | 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: |
| | 277 | {{{#!python |
| | 278 | from trac.core import * |
| | 279 | from trac.config import BoolOption |
| | 280 | from trac.web.api import IAuthenticator |
| | 281 | |
| | 282 | class MyRemoteUserAuthenticator(Component): |
| | 283 | |
| | 284 | implements(IAuthenticator) |
| | 285 | |
| | 286 | obey_remote_user_header = BoolOption('trac', 'obey_remote_user_header', 'false', |
| | 287 | """Whether the 'Remote-User:' HTTP header is to be trusted for user logins |
| | 288 | (''since ??.??').""") |
| | 289 | |
| | 290 | def authenticate(self, req): |
| | 291 | if self.obey_remote_user_header and req.get_header('Remote-User'): |
| | 292 | return req.get_header('Remote-User') |
| | 293 | return None |
| | 294 | |
| | 295 | }}} |
| | 296 | |
| | 297 | Add this new parameter to your TracIni: |
| | 298 | {{{#!ini |
| | 299 | [trac] |
| | 300 | ... |
| | 301 | obey_remote_user_header = true |
| | 302 | ... |
| | 303 | }}} |
| | 304 | |
| | 305 | Run tracd: |
| | 306 | {{{#!sh |
| | 307 | tracd -p 8101 -s proxified --base-path=/project/proxified |
