A role is created with a conditional query. The role is automatically assigned to a user as normal behaviour. Navigating to Manage -> User -> Roles in the admin UI, the role appears in the list but Grant Type "Conditional" doesn't appear in the "Grant" column.
Testing IDM 6.5 and 7.0.1 via REST queries returned the _grantType variable
Screenshots for IDM 6.5 and IDM 7.0.1 are attached for visual comparison.
