I created One group named as Super user which inherited from all open erp managers groups.

If I assign that group to user then that user will work like or got access like administrator. It work fine if I assign that group to user that specific user will get all access.

But if I uncheck that group from settings --> users --> Access Rights then also that user having same access like administrator. So what can I do now to get original access to that user.... ?

Thank you In advance :)
