| 77 | | === Configuring Authentication === |
| 78 | | |
| 79 | | Creating password files and configuring authentication works similar to the process for [wiki:TracCgi#AddingAuthentication CGI]: |
| 80 | | {{{ |
| 81 | | #!xml |
| 82 | | <Location /projects/myproject/login> |
| 83 | | AuthType Basic |
| 84 | | AuthName "myproject" |
| 85 | | AuthUserFile /var/trac/myproject/.htpasswd |
| 86 | | Require valid-user |
| 87 | | </Location> |
| 88 | | }}} |
| 89 | | |
| 90 | | Configuration for mod_ldap authentication in Apache is a bit tricky (httpd 2.2.x and OpenLDAP: slapd 2.3.19) |
| 91 | | |
| 92 | | 1. You need to load the following modules in Apache httpd.conf |
| 93 | | {{{ |
| 94 | | LoadModule ldap_module modules/mod_ldap.so |
| 95 | | LoadModule authnz_ldap_module modules/mod_authnz_ldap.so |
| 96 | | }}} |
| 97 | | |
| 98 | | 2. Your httpd.conf also needs to look something like: |
| 99 | | |
| 100 | | {{{ |
| 101 | | #!xml |
| 102 | | <Location /trac/> |
| 103 | | SetHandler mod_python |
| 104 | | PythonInterpreter main_interpreter |
| 105 | | PythonHandler trac.web.modpython_frontend |
| 106 | | PythonOption TracEnv /home/trac/ |
| 107 | | PythonOption TracUriRoot /trac/ |
| 108 | | Order deny,allow |
| 109 | | Deny from all |
| 110 | | Allow from 192.168.11.0/24 |
| 111 | | AuthType Basic |
| 112 | | AuthName "Trac" |
| 113 | | AuthBasicProvider "ldap" |
| 114 | | AuthLDAPURL "ldap://127.0.0.1/dc=example,dc=co,dc=ke?uid?sub?(objectClass=inetOrgPerson)" |
| 115 | | authzldapauthoritative Off |
| 116 | | require valid-user |
| 117 | | </Location> |
| 118 | | }}} |
| 119 | | |
| 120 | | Or the LDAP interface to a Microsoft Active Directory: |
| 121 | | |
| 122 | | {{{ |
| 123 | | #!xml |
| 124 | | <Location /trac/> |
| 125 | | SetHandler mod_python |
| 126 | | PythonInterpreter main_interpreter |
| 127 | | PythonHandler trac.web.modpython_frontend |
| 128 | | PythonOption TracEnv /home/trac/ |
| 129 | | PythonOption TracUriRoot /trac/ |
| 130 | | Order deny,allow |
| 131 | | Deny from all |
| 132 | | Allow from 192.168.11.0/24 |
| 133 | | AuthType Basic |
| 134 | | AuthName "Trac" |
| 135 | | AuthBasicProvider "ldap" |
| 136 | | AuthLDAPURL "ldap://adserver.company.com:3268/DC=company,DC=com?sAMAccountName?sub?(objectClass=user)" |
| 137 | | AuthLDAPBindDN ldap-auth-user@company.com |
| 138 | | AuthLDAPBindPassword "the_password" |
| 139 | | authzldapauthoritative Off |
| 140 | | # require valid-user |
| 141 | | require ldap-group CN=Trac Users,CN=Users,DC=company,DC=com |
| 142 | | </Location> |
| 143 | | }}} |
| 144 | | |
| 145 | | Note 1: This is the case where the LDAP search will get around the multiple OUs, conecting to Global Catalog Server portion of AD (Notice the port is 3268, not the normal LDAP 389). The GCS is basically a "flattened" tree which allows searching for a user without knowing to which OU they belong. |
| 146 | | |
| 147 | | Note 2: Active Directory requires an authenticating user/password to access records (AuthLDAPBindDN and AuthLDAPBindPassword). |
| 148 | | |
| 149 | | Note 3: The directive "require ldap-group ..." specifies an AD group whose members are allowed access. |

| 266 | | In Python 2.4, some version of Expat (an XML parser library written in C) is used, |
| 267 | | and if Apache is using another version, this results in segmentation faults. |
| 268 | | As Trac 0.11 is using Genshi, which will indirectly use Expat, that problem |
| 269 | | can now hit you even if everything was working fine before with Trac 0.10. |

| | 242 | In Python 2.4, some version of [http://expat.sourceforge.net/ Expat] (an XML parser library written in C) is used and if Apache is using another version, this results in segmentation faults. |
| | 243 | As Trac 0.11 is using Genshi, which will indirectly use Expat, that problem can now hit you even if everything was working fine before with Trac 0.10. This problem has not been reported for Python 2.5+, so best to upgrade. |

| 277 | | === Problem with virtual host configuration === |
| 278 | | |
| 279 | | If the <Location /> directive is used, setting the `DocumentRoot` may result in a ''403 (Forbidden)'' error. Either remove the `DocumentRoot` directive, or make sure that accessing the directory it points is allowed (in a corresponding `<Directory>` block). |
| 280 | | |
| 281 | | Using <Location /> together with `SetHandler` resulted in having everything handled by mod_python, which leads to not being able download any CSS or images/icons. I used <Location /trac> `SetHandler None` </Location> to circumvent the problem, though I do not know if this is the most elegant solution. |

| | 254 | |
| | 255 | === Problem with zipped egg |
| | 256 | |
| | 257 | It's possible that your version of mod_python will not import modules from zipped eggs. If you encounter an `ImportError: No module named trac` in your Apache logs but you think everything is where it should be, this might be your problem. Look in your site-packages directory; if the Trac module appears as a ''file'' rather than a ''directory'', then this might be your problem. To rectify, try installing Trac using the `--always-unzip` option, like this: |
| | 258 | |
| | 259 | {{{ |
| | 260 | easy_install --always-unzip Trac-0.12b1.zip |
| | 261 | }}} |

| 333 | | See also [http://subversion.tigris.org/faq.html#reposperms] |
| 334 | | |
| 335 | | === FreeBSD issues === |
| 336 | | Pay attention to the version of the installed mod_python and sqlite packages. Ports have both the new and old ones, but earlier versions of pysqlite and mod_python won't integrate as the former requires threaded support in python, and the latter requires a threadless install. |
| 337 | | |
| 338 | | If you compiled and installed apache2, apache wouldn´t support threads (cause it doesn´t work very well on FreeBSD). You could force thread support when running ./configure for apache, using --enable-threads, but this isn´t recommendable. |
| 339 | | The best option [http://modpython.org/pipermail/mod_python/2006-September/021983.html seems to be] adding to /usr/local/apache2/bin/ennvars the line |

| 346 | | |
| 347 | | If you get the following Trac Error `Unsupported version control system "svn"` only under mod_python, though it works well on the command-line and even with TracStandalone, chances are that you forgot to add the path to the Python bindings with the [TracModPython#ConfiguringPythonPath PythonPath] directive. (The better way is to add a link to the bindings in the Python `site-packages` directory, or create a `.pth` file in that directory.) |
| 348 | | |
| 349 | | If this is not the case, it's possible that you're using Subversion libraries that are binary incompatible with the apache ones (an incompatibility of the `apr` libraries is usually the cause). In that case, you also won't be able to use the svn modules for Apache (`mod_dav_svn`). |
| 350 | | |
| 351 | | You also need a recent version of `mod_python` in order to avoid a runtime error ({{{argument number 2: a 'apr_pool_t *' is expected}}}) due to the default usage of multiple sub-interpreters. 3.2.8 ''should'' work, though it's probably better to use the workaround described in [trac:#3371 #3371], in order to force the use of the main interpreter: |
