---------------------------------+------------------------------------------
 I'm running Trac 0.9 with Mod Python and noticed something odd. I don't
 know however if this is Trac related, but it sure doesn't work in a way I
 thought it would be.

 Running Debian.

 apache2 -v output:
 Server version: Apache/2.0.54
 Server built:   Sep  5 2005 11:11:08

 Trac-admin output:
 trac-admin - The Trac Administration Console 0.9

 Mod python version is 3.1.3


 Apache2 config part which creates the odd situation:

 <IfModule mod_negotiation.c>
 <IfModule mod_include.c>
     Alias /error/ "/usr/share/apache2/error/"

     <Directory "/usr/share/apache2/error">

 </IfModule>
 </IfModule>

 I use this apache virtual host config for trac:

 <VirtualHost *:443>
         ServerName sub.domain.com
         DocumentRoot /var/www/sub.domain.com/

         SSLEngine On
         SSLCertificateFile /etc/apache2/ssl/apache.pem
         SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
         SSLCipherSuite
 ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL

         SSLOptions +StdEnvVars



         Alias /trac /usr/share/trac/htdocs/
     <Location />
         SetHandler mod_python
         PythonHandler trac.web.modpython_frontend
         PythonOption TracEnv /var/www/sub.domain.com
         PythonOption TracUriRoot /
         suPHP_Engine Off
         SecFilterEngine Off
 </Location>
     <Location /login>
                 AuthType Basic
                 AuthName "Trac - Project Management and Version Control"
                 AuthUserFile /etc/apache2/.htpasswd-svn
                 Require valid-user
                 SecFilterEngine Off
     </Location>
 <Location /trac>
               SetHandler None
                 </Location>

         ErrorLog /var/log/apache2/error.log
         CustomLog /var/log/apache2/access.log combined
         LogLevel warn

 </VirtualHost>


 When I have it like this Trac issues this error when I want to login:
 No handler matched request to /error/HTTP_UNAUTHORIZED.html.var

 When I comment out this line in the apache config part:
 ErrorDocument 401 /error/HTTP_UNAUTHORIZED.html.var

 It works OK.

 A workaround which I got is adding this line in my virtualhost:
 ErrorDocument 401 default

 Then things will work Ok.

 Hope someone can research this.
