Trac doesn't work with Virtual Hosts - Authentication information not available

[Marc]

Here is my VirtualHost configuration

<VirtualHost *:80>
ServerName myproject.host.com
# We can't use Location / because then /login also gets sent to
mod_python
<Location />
SetHandler mod_python
PythonInterpreter main_interpreter
PythonHandler trac.web.modpython_frontend
PythonOption TracEnv /var/trac/myproject/
PythonOption TracUriRoot /
SetEnv PYTHON_EGG_CACHE /var/trac/.egg-cache/
</Location>

<Location /login>
AuthType Basic
AuthName "Trac (Subversion) access"
AuthUserFile /etc/apache2/svn.passwd
Require valid-user
</Location>
</VirtualHost>

The problem is that the Login location does not work. Trac' (NOT
mod_python), hijacks everything and sends it to itself. Even setting
SetHandler None in <Location /login> does nothing.

The famous "Authentication information not available" message appears.
Apache never is able to handle the <Location /login>, Trac hijacks it.

Has anybody ever solved this long-standing issue? It seems to be a
problem with Trac, because other mod_python apps like Django use the
SetHandler None solution and it works fine.

Using DocumentRoot does no difference whatsoever.

Thanks.

If I understand correctly, you *want* Trac to handle /login. Trac has
a request handler for /login that handles generating the Trac cookie
if authentication information is provided by the server. Otherwise
Apache is just authenticating /login and then doing nothing at that
location.

Yes the problem is that apache is not prompting the login form in /
login. It just goes straight to Trac.

I have fixed it now, I've set the logging level to debug and saw this

[Tue Aug 04 03:21:06 2009] [debug] mod_deflate.c(632): [client myip]
Zlib: Compressed 4133 to 1507 : URL /include/error.php, referer:
http://myproject.url.com/

I removed this line from my apache conf:

ErrorDocument 401 /include/error.php?401

It was my custom error handler.

What I did now is set: ErrorDocument 401 default inside the <Location /
login>

Everything works now, anybody able to explain the mechanism behind the
401 with Trac?

Thanks!

Here is the Trac bug for future reference. They did the same solution
as me.

Simpler: Put a '#' in front of the 'ErrorDocument 401' line :)
