Page by page access restriction#
Insert text as below at the top of each page you wish to restrict changing the names appropriately (authenticated means anyone logged in).
[{ALLOW view Janne,Mike Morris,Authenticated}]
[{ALLOW edit Janne,Managers}]
You can set access at user or group level though take care to use usernames and not display names.
Granting edit access will also grant view access, you don't need to grant privileges in both areas.
More info is available on this on the JSPWiki documentation - page access
