squirrelmail no such user `www-data:www-data'

[jacek_arwal]

I want to configure squirrelmail on ISPConfig 2. I have Mandriva Linux 2009.1 . I am configuring using http://www.howtoforge.org/squirrelmail_ispconfig . In step 6 I am writing :

chown -R www-data:www-data data
chown -R www-data:www-data sqmattachments

but I receive an error

no such user `www-data:www-data'

[till]

You can see the name of the apache user and group that is used in Mandriva in the apache2.conf or httpd.conf file. Then use this username instead of www-data in the commands.

Thanks it worked. On mandriva use and group are apache.
