Although it is possible to define rights per page, it is less common to do so. - In the space or global preferences, the administrator defines rights for all the pages in that space/wiki. - The non-administrators are prevented from further editing the space rights by defining restricting rights on the space preferences page. This is done by editing the page access rights for <Space>.WebPreferences Although now a user can alter the rights for one page, not all the rights can be granted/restricted on the page level. Administration, programming and registration rights can only be granted/blocked globally. This means that the worse a user can do is revoke other' view/edit rights for one page. However, with a little hacking, the platform code can be changed to: - treat rights object differently, so that only users with administration rights can change the rights (needs a deeper knowledge of how the platform works), or - completely ignore page access rights, except for the space preferences page (a bit simpler than the previous to implement, but looses some granularity). This can even be done in a pluggable XWikiRightService implementation as an alternative to the default one. -- Sergiu Dumitriu http://purl.org/net/sergiu/
