Erros em autenticação no apache

[Leandro Moreira <leandro@leandromoreira.eti.br>]

Caros,
Estou usando o seguinte host no meu apache2:
#
# This is a sample config that
# should be encapsulated into
# a VirtualHost section.

#    SuexecUserGroup dspam dspam
#    Addhandler cgi-script .cgi
#    Options +ExecCGI -Indexes

#    Alias /dspam /var/www/dspam
    <Directory /var/www/dspam>
        Addhandler cgi-script .cgi
        Options +ExecCGI -Indexes
        DirectoryIndex dspam.cgi

# Note: you have to add www-data to the 'shadow'
#       group to make this work. You whould
#       better change for another authentication bakend
#AuthPAM_Enabled on

        AuthType Basic
        AllowOverride None
        AuthName "DSPAM Control Center"
        AuthUserFile /var/www/dspam/htpasswd.users
        Require valid-user
    </Directory>


Quando tento logar da o seguinte erro:

[Thu Dec 13 23:21:31 2007] [error] [client 201.78.75.148] GROUP: root not
in required group(s)., referer:

[Thu Dec 13 23:22:14 2007] [error] [client 201.78.75.148] GROUP: root not
in required group(s)., referer:
http://www.leandromoreira.eti.br/dspam/dspam.cgi?template=analysis

Ja tentei de tudo e não consigo resolver esse erro, será que alguem pode
me dar uma luz do que esta acontecendo.

Att.
