Use this
wget http://www.pialasse.com/RPMS/smeserver-user-webspace-0.1-5.SME7.noarch.rpm
yum install smeserver-user-webspace-0.1-5.SME7.noarch.rpm
rm smeserver-user-webspace-0.1-5.SME7.noarch.rpm
signal-event post-upgrade
signal-event reboot
If you want to disable user webspace:
/sbin/e-smith/config set UserPublicWeb off
/sbin/e-smith/expand-template /etc/httpd/conf/httpd.conf
service httpd restart
I have tested this on 7.0 so i don't know how it'll work on 7.1.3 but i think that it will work.
http://www.yourdomain/username will hold their websites.
Another option is to make an ibay and use remoteuseraccess contrib to forward the users from their home folder to the ibay.
I personaly like the last option.
