I've got few answers for you:
- group accounts are not supported in recommendations - these accounts just ignore mngmt actions/recommendations settings that you made -> so all group accounts are able to see Recommendations page, but are not able to execute any of the recommendations (this describe behaviour that you posted on screenshots)
- you need to use individual accounts
- unfortunately, there is a bug on new version - VIM 7.1, and setting "Allow Recommendations" is not working at all (it is working on VIM 7.0)
- if this is important for you, please open a case on support
I am on version 7.0 and this is a individual account not an AD account and not a AD group account -
Please open a ticket with support, we will need diagnostics for this.
This should definitely work -> when you disallow recommendations for some account - access denied page should appear
