User Access to specific website

Hi,
I tried to find this issue with the forum, but couldn’t able to.
Very first time I integrated Piwik at my server. I have couple of websites and couple of user to whom I want to give access.
My question is, how can I give access to any user’s for specific website? So they can see only some websites which I given the access. Not any other websites tracking on same server.

I will really appreciate your help.

Thanks in advance,
Deecee
