 yes, but if you define a harder rule at page level, the space level one will
 be overlapsed by the new rule.

I get your point. thanks. But I think it keep being counter-intuitive 
for me that once I grant some rights on a page to a group, the fact of 
explicitly adding some user (belonging or not to the previous group) 
rights to the same page prevents members of the original granted group, 
included the owner, to access the document.


   
 Thanks!
 
 The only exception I can think off that would help your usecase (but is
   
 not
 
 implemented) is to have additional special rights for the document
   
 Creator.
 
 Right now the creator gets DELETE right as an additional behavior. Maybe
   
 we
 
 should always grant VIEW and EDIT to the creator.
 This way, at least, he could fix the rights behavior (by giving rights
   
 also
 
 to GroupA).

 Another thing that is missing is a warning that by giving that right, the
 giver will lose it.

 Hi,

 We ran into a rights problem, which might be the result of ignorance,
 
 but
 
 could also be caused by a perceptual omission in the rights model. The
 following happened:

 1. created space, with explicit rights on group 'GroupA' (this
 automatically locks out users who are not a member of this group) = ok
 2. create/edit a page as user 'UserA', member of 'GroupA' = ok
 3. UserA (owner/creator of the document) grants view rights to user
 'UserB', NOT in GroupA = problems!

 Now the creator/owner of the document (UserA) can NOT view his own
 
 document
 
 anymore! Same for problem for every other user in 'GroupA'.

 I figured that this is correct from a certain point of view: an explicit
 view for a specific user locks out all other users, but that includes
 
 the
 
 owner and all other users, including those in 'GroupA', with correct
 
 rights
 
 at the space level.
 A possible solution is to grant GroupA explicitly at the same time you
 grant a specific user access to a certain page, but people will forget
 
 to do
 
 so.

 My question is: did we do anything wrong, and is it possible to manage
 
 the
 
 rights in a way that prevents this counter-intuitive behaviour?

 I have the feeling that the rights model lacks real-inheritance: when
 checking permissions for a user, it should return the permissions
 
 including
 
 that of the group as if it were his explicit permissions, also for pages
 that inherit rights from the space. E.g.
 hasView('UserA') should always return 'True' when the group he belongs
 
 to
 
 has view rights at the space level.
 Now it apparently returns 'False' when there is an implicit override by
 granting a user view rights. Or does inheritance from the space levels
 
 stops
 
 working as soon as there's any kind of override on a specific page?

 A possible but crude work-around could be using some intelligent trigger
 functions in the database to explicitly add all rights from the space to
 
 the
 
 specific document as soon as an XWikiRights object is written, but
 
 that's
 
 kind of a last resort.

 Could you help me? I hope for a better solution!

 Thanks,
 Wouter

[xwiki-users] grant rights to a specific user

2010-11-19 Thread Wouter Boasson
Hi,

We ran into a rights problem, which might be the result of ignorance, but could 
also be caused by a perceptual omission in the rights model. The following 
happened:

1. created space, with explicit rights on group 'GroupA' (this automatically 
locks out users who are not a member of this group) = ok
2. create/edit a page as user 'UserA', member of 'GroupA' = ok
3. UserA (owner/creator of the document) grants view rights to user 'UserB', 
NOT in GroupA = problems!

Now the creator/owner of the document (UserA) can NOT view his own document 
anymore! Same for problem for every other user in 'GroupA'.

I figured that this is correct from a certain point of view: an explicit view 
for a specific user locks out all other users, but that includes the owner and 
all other users, including those in 'GroupA', with correct rights at the space
