Apache2 and mod_auth_mysql?

[Jan Johansson]

I am trying to use mod_auth_mysql for Apache2, and even tho it is linked
from mods-enabled, I get 

"Invalid command 'AuthMySQLHost', perhaps mis-spelled or defined by a
module not included in the server configuration" any hints? 

(yes, I restarted Apache2)


Versions:
apache2 2.0.55-4.1
libapache2-mod-auth-mysql       4.3.9-2.1

Here is my .htaccess
AuthName "My Authorization test"
    AuthType Basic
    AuthMySQLHost localhost
    AuthMySQLDB test
    AuthMySQLUserTable "user_info"
    require valid-user

haven:~# ls /etc/apache2/mods-enabled/
auth_mysql.load  cgi.load  php5.conf  php5.load  ssl.conf  ssl.load
haven:~#
