How can I restrict user groups to view selected host groups

[stranger]

Hello all,
I need to restrict certain users (user groups) so that they can and interact with only certain hosts (host groups). Does anybody know how to do this? :confused: Any help would be much appreciated. :D

as admin click [configure] / [user] / <username>

there you can deny access by default and then only allow to watch certain host- and/or item ids.

AFAIK, there's no way to deny/allow access to whole host groups...
