Is it somehow possible, on the admin site of a page, to filter/sort the access right groups and users?
If you have a lot of users and groups and you have granted e.g. write access rights for a group Football, it would be nice to sort the write access right so that on top of the list the groups are listed which have the write access (Football in my example).
Is this already possible somehow or is this a feature request?
How are others make sure to have valid access rights in a large installation with many groups and users?
For now, I use a wiki page to track the permission. To enforce permissions, I “block” accidental inheritance, I assign an empty group with all the permissions on the level I would like to enforce the permissions.
As for any structure, it is important to keep it simple …
Is there a page or would it possible to have a hidden page which shows the access rights of a page? Currently, is pretty hard to see which users/groups have access to a site or not.
No idea. The way open source works is that features are implemented or bugs are fixed when someone sponsors them (whether it’s someone paying out of his/her own free time or a company paying someone to work on it). Right now, all I can tell you is that I haven’t heard anyone being active on this.
