This doesn't have anything to do with authz, it just means you haven't configured authentication with your web server. See TracCgi#AddingAuthentication for more information. (Basically the same for mod_python)

[matthew.donald@…]

Traced failure cause to a silent httpd.conf error.

The TracOnWindows wiki page (since updated) specifed the following sample Apache config:

  <Location "/trac/project/login">
    AuthType Basic
    AuthName "Trac Project"
    AuthUserFile C:/trac/.htaccess
    Require valid-user
  </Location>

This config parsed correctly and Apache would start without error.

However, when a user clicked the "login" link, Apache would not match the login Location directive, and a HTTP 401 response was not returned. This meant that when Trac's auth code executed, no remote user information was present in the request and the assertion consequently failed.

The question is, why did the <Location "/trac/project/login"> directive fail to match? It turns out to be the presence of the double quotes.

Removing the double quotes fixes the problem.

  <Location /trac/project/login>
    AuthType Basic
    AuthName "Trac Project"
    AuthUserFile C:/trac/.htaccess
    Require valid-user
  </Location>

I'm running Trac from a Python HTTP server (twisted.web2) via WSGI and do not have Apache installed at all. I get this error when I try to login, and don't see any way around that in any of the docs. So it's a real problem for me.

[mgood]

edsuom: Well, WSGI opens up many new ways of running Trac, and twisted.web2 is not one tested and documented yet, so you're kind of on your own for now. However, the point still applies that you will need to set up your server to do HTTP authentication for you to login to Trac. I'm not sure what Twisted provides for doing this, so you will probably need to check their documentation or mailing list for help with this. It may also be possible to use WSGI middleware to handle authentication such as [http://pythonpaste.org/module-paste.auth.html paste.auth]. Also take a look at the form-based auth from AccountManager or ask on the MailingList to see if any one has done this already.

Same Problem here I also tried <LocationMatch /login>, with and without quotes, with trailing blank and without, but nothing worked... But if I just use <Location /> everything works fine Looks like Apache doesn't parse the Subdomain urls correctly Is there any way to fix that (mod_rewrite or stuff like that)?

Best wishes, Felix

ps: was it ok to reopen this ticket or should I have created a new one?

This is a config issue, so please use the MailingList to reach a larger portion of the user community for support.

Have you read the documentation section linked to in the error message? If so, please read the comments above for the previous times this ticket has been closed and ask on the MailingList for more help.

Hi!

I've set up the environment, as described in the mentioned page. I want to use the same password file for svn and trac. Still I can browse the repository, although the login page still gives 500 Internal Server Error. From the apache2 config:

<Location /trac/[^/]+/login">

AuthType? Basic AuthName? "Subversion Repository" AuthUserFile? /etc/apache2/passwords Require valid-user

</Location>
