This PR is not completed yet. It exposed an example usage for the newly-introduced sudoers gatherer.

Looks good!
Ideally, we would use other gatherer to get the real list of SIDs, and iterate over it instead of getting the unique list of users from the same data.
Either way, the example is nice!

Ideally, we would use other gatherer to get the real list of SIDs, and iterate over it instead of getting the unique list of users from the same data.

I don't know if it would suit this specific check. The real list of SIDs is file-based and it may include unused SIDs for which the user has been removed.

Hence it would make the check is every SAP user well configured? fail; it would be to combine both information in another check, though, to verify is there an unused SAP system?.

I have one check in PR#50 that addresses this requirement. I am getting the SID from ini_files gatherer.
