Apache 2 setup question

[Leila Lappin]

Hello all,

I have apache 2 installed with root password under
/etc/httpd.  How can I configure this to have setup
under /home/user/public_html?  So far I have modified
the values of <DocumentRoot> and  and <Document> in
httpd.conf to point to the desired user directory. 
But I cannot access the directory, I get 403 error the
message reads “You don’t have permission to access /
on this server”
