Limiting web frontend display

Hi, is it possible to control what information a specific user sees. As I have a requirment which may mean a client might need accees to the web front end of nagios to view information about their network that is being monitored.

For example their server is SRV10, but nagios is also monitoring servers SRV1-9. The user should only see information relating to SRV10.

Regards
Martin.
