You don't have permission to access /xxxx on this server

powah

When I set
DocumentRoot "/home/powah/gui/content"
in httpd.conf

The web page
http://localhost/xxxx
has permission problem which is unexpected.
How to fix it?

Forbidden

You don't have permission to access /xxxx on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
Apache/2.0.52 (Fedora) Server at localhost Port 80

When I set
DocumentRoot "/etc/httpd/htdocs"
in httpd.conf

The web page
http://localhost/xxxx
has correct behavior:

Not Found

The requested URL /xxxx was not found on this server.
Apache/2.0.52 (Fedora) Server at localhost Port 80

The permission of folders are

ls -ld /etc/httpd/htdocs

drwxr-xr-x 10 root root 4096 Apr 18 17:04 /etc/httpd/htdocs

ls -ld /home/powah/gui/content

drwxrwxr-x 4 powah powah 4096 Apr 19 10:54 /home/powah/gui/content

I use FC3 linux.

This isn't an apache forum but there could be several reasons why it's not working.

You'll probably need to change more than just "DocumentRoot".
Apache runs as user nobody by default. User nobody doesn't have read, write, or execute permissions in your home directory unless you change permission on /home.
Fedora with Selinux is know to cause problem with programs accessing the filesystem. Fedora most likely isn't the problem here so I'd start with the first two things i mentioned.
