PHPPGADMIN 4.2.2 access problem from client ip

Hi Team,

I installed phppgadmin in Ubuntu10.04 LTS. I tried to allow only local user connection but it is not working it throws below error in the browser.
Forbidden

You don't have permission to access /phppgadmin/ on this server.
Apache/2.2.22 (Ubuntu) Server at 10.44.0.218 Port 80

My phppgadmin configuration details:
root@webstar:~# cat /etc/apache2/conf.d/phppgadmin
Alias /phppgadmin /usr/share/phppgadmin

<Directory /usr/share/phppgadmin>
