Is there a way to unimportRoles or disable capabilities for a certain role? I don't believe so based on the documentation:
[role_<roleName>]
<capability> = <enabled>
...
* Roles inherit all capabilities from imported roles, and inherited
capabilities cannot be disabled.
...
importRoles = <string>
* Semicolon delimited list of other roles and their associated capabilities
that should be imported.
* Importing other roles also imports the other aspects of that role, such as
allowed indexes to search.
We would like to create a custom role to override inherited capabilities. An example would be a system account which has less capabilities but has inherited user role capabilities. Right now it seems like an RFE.
One solution might be to create a new role (ie. user-system) with fewer capabilities than the normal 'user' role. Then have your 'system-account' role inherit this new 'user-system' role along with the capabilities assigned to it.
Is this what you are looking to achieve?
Thanks for your response but this is not what I'm looking for. Since group membership allows a group owner to add their system-account to their own group, the system-account then inherits user capabilities. Even if I find out about the system-account and drop it into a system-account-role, it doesn't uninherit the capabilities already granted by a user role.
This is why I am looking for a way to uninherit or disable capabilities.
