Issue status update for 
Post a follow up: 

 Project:      Drupal
 Version:      cvs
 Component:    user.module
 Category:     feature requests
 Priority:     normal
 Assigned to:  Anonymous
 Reported by:  budda
 Updated by:   JoranLawrence
 Status:       patch (code needs work)

I am sort of a newbie to Drupal, so excuse my intrusion in a clearly
high-level drupal development discussion.  However, I need this
functionality for a project and have thought about the issue/problem. 
While my suggestion might not be a realistic solution (because of the
drupal core); it might move the conversation towards one. 

I think Roles should be able to carry a weight attribute.  

Reason 1: It could used to print the 'permissions' page of the access
control in a logical left to right (less to more) access based on

Reason 2: The same logic above would be used so a user could only
change permissions for less weighted roles than their maximum assigned

Reason 3: Users could not assign themselves to roles beyond the weight
of their assigned role.

I have not looked closely at the code of user.module or the patch, so I
don't know how difficult this would be to implement.  However, I think
this functionality is critical.  I would love to see it 4.7.  If there
is anything I can do to help, please let me know.

When a user role is granted 'administer users' permission this allows
them to not only edit any users profile, but also amend the access
control list, even for their own role. This means a moderator could
actually increase their own permissions to enable further access to
Drupal site settings.

To prevent this I have split the user module permissions further to
provide a new permission setting for each role - "administer
permissions". Enabling this permission for any role will provide the
user with access to the "access control" pages and functionality.

Patch attached to add additional permission and change menu access
checks as needed.

+1 on idea (I haven't patched and tested), makes sense to me as a
distinct permission.

+1 from me also, although I also haven't tested the patch.  This
"escalate myself" privilege is a big problem!

This seems like a real requirement for proper permissions handling.

The patch looks good from a code review, but I have not tested it yet.

I've upated the patch to make it work from the root directory. I also
fixed a minor formating issue.

While I think that this patch is usefull, I think it isn't general
enough. Once you got the "admin users" permission you can grant
yourself any defined role. So this patch is only usefull if none of the
defined rules has all permissions. I have a number of sites where this
would be sufficient, but we try to keep Drupal usable for all use
cases. Applying thi spatch as it is now would mean to pretend false
security in a lot of cases.

So, what would be ''the'' solution?
* only allow users with a role one ' above' the to-be-changed-user to
change that user? And in that case, how to find the one-above in
drupals non-hierarchical user system,
* only allow users with one role to lever themselves> the patch tries
this, but essentially does not fix the issue. anyone with ''administer
permissions'' can now leverage himself.
* allow only uid1 to dedicate users that can change permissions? which
can be a problem in big environments?

I cannot see any real solution, IMO the *nix solution, the sudo, is the
best one: just introduce a role that can act like uid 1, and leave
permissions to my 3rd solution. 

but in that case this issue whould have to be moved and renamed.

I think a possible solution would be to take "chenge roles" out from the
"administer users" permission and move it to the proposed "administer
permissions" permission. Ie you can only change roles if you can change
permissions. This would make sense to me. People who have "administer
users" permission but not "administer permissions" could still change
other user settings.

Killes: isn't this what the patch is doing already?

no. there are no changes to user_edit_form
