How can limit access to dashboards?

[1862347ba9566e72a47d (Tatiana)]

Kibana version 6.0
I created a new user1 in kibana.
Then assign role to use a user for Dashboard Only mode.
User1 has by default accessed dashboard1, dashboard2, dashboard3.
I want him to get access only to the dashboard3.
Created a separate index1 for the dashboard3. Gave the user1 access to this index1
When accessing the kibana comes an error

Config: Error 403 Forbidden: action [indices:data/write/update] is unauthorized for user [user1]: [security_exception] action [indices:data/write/update] is unauthorized for user [user1]

Dashboard only mode currently only limits the user to the dashboard app entirely, not to specific dashboards individually. We have some upcoming features (not yet available) that will allow you to silo content from users. We're hoping to have them in during the 6.x roadmap.
