There should be an audit record created while using external auth source and the external group membership changes for a user (on the remote side)

- set up an external auth source (e.g. freeIPA)
- create a user on it
- create an external group on it
- login with the external user id
- (the user should be created)
- on foreman, create a user group and map it to the external group you created
- hit refresh to load the user mappings (the ext. user should be added to the UG)
- now, on the external auth source, remove the user from the group
- on foreman, navigate to the UG and at the external group mapping tab, hit refresh again
- (the user should be removed from the group)
- list all audits and notice, the action is not audited at all
