Login doesnt work

[tobyf@…]

Maybe I'm just to stupid:

• This config will work:

  <VirtualHost 83.151.25.254:80>
      DocumentRoot /home/oh-dev/tobyf.de/trac
      ServerName oh-trac.tobyf.de
      ServerAdmin webmaster@tobyf.de
  
      <Location "/">
          SetHandler mod_python
          PythonHandler trac.web.modpython_frontend
          PythonOption TracEnv /home/oh-dev/tobyf.de/trac
          PythonOption TracUriRoot /
          PythonDebug on
  #    </Location>
  
  #    <Location "/login">
          AuthType Basic
          AuthName "OpenHope Teambereich"
          AuthUserFile /home/oh-dev/tobyf.de/trac/trac_login
          Require valid-user
      </Location>
  
      ErrorLog /var/log/apache2/error.trac.log
      CustomLog /var/log/apache2/access.trac.log combined
  </VirtualHost>
  

• This one not:

  <VirtualHost 83.151.25.254:80>
      DocumentRoot /home/oh-dev/tobyf.de/trac
      ServerName oh-trac.tobyf.de
      ServerAdmin webmaster@tobyf.de
  
      <Location "/">
          SetHandler mod_python
          PythonHandler trac.web.modpython_frontend
          PythonOption TracEnv /home/oh-dev/tobyf.de/trac
          PythonOption TracUriRoot /
          PythonDebug on
      </Location>
  
      <Location "/login">
          AuthType Basic
          AuthName "OpenHope Teambereich"
          AuthUserFile /home/oh-dev/tobyf.de/trac/trac_login
          Require valid-user
      </Location>
  
      ErrorLog /var/log/apache2/error.trac.log
      CustomLog /var/log/apache2/access.trac.log combined
  </VirtualHost>
  

I'm using Debian Edge with Apache 2.2.

All I get using the lower config is

Internal Error

Authentication information not available. Please refer to the installation documentation.

I have check all logs and found nothing relevant, whether in apache-logs nor in trac-logs.
If I move the installation to another path, eg. oh-trac.tobyf.de/trac it will work.

I think this is a very strange behaviour, maybe I made something wrong?
