OK... Just a review, don't be offended by this if you have already done so...
1. create or clone the role in the administration/ roles view
2. in the inventory / hosts & clusters view, select a context on the left and select the permissions tab on the right. Right-click -> new permission
3. Add a user or group and select your new role.
If that does not work, post a screen shot of the error message.
