Summary

This PR implements a number of enhancements to the platform to allow administrators to require users' consent to storage and usage of data. This is an essential part of GDPR compliance in Europe.

In essence the login experience is enhanced with a new step "DataConsent" which kicks in once the admin has activated the feature for the site. A user's consent is recorded as well as the time it was done. The action is also logged. This allows basic forensics to take place. For more advanced scenarios this solution also allows the Data Consent step to be done elsewhere on the site through a "Consent Redirect" setting.

Account removal

An integral part of consent is the option to opt out and even delete one's profile. Because it is hard to tell if all extensions will respond well to a user being eliminated from the database, the solution provides three mechanisms for user account deletion (by the user):

  1. Off. Account deletion remains the responsability of the site owner.
  2. Manual. The user is marked as wishing to be removed and the account is unauthorized.
  3. Delayed Hard Delete (default). The user is marked as wishing to be removed and deleted. The user will be removed after a specified time. This allows admins to recuprate an account in case of a mishap during the grace period.
  4. Hard Delete. The account is immediately removed.

Note that to achieve number 3, a scheduled task has been added.

Discussion

Although care has been taken to provide a powerful mechanism that will address most needs for GDPR compliance in this area it is noted that always be more powerful and complete. The criteria with which I began this were that it would be as minimal an intervention in terms of code changes and additions and it would allow 3rd party developers to leverage this to create a more powerful system.

Testing

Note what needs to be done is to check more complex integration scenarios With that I’m thinking:

  • multi portal setups with portal groups
  • users that have to go through various combo’s of: Data Consent, Update Password and Complete Profile. These items are now “on the same level” in the framework, so the risk of interference is greatest at that point.
  • test the extension point. Can you create something simple to retrieve the user from the token and then do some fancy consent logic and mark the user as consented in the framework?

Isn't it irritation/misleading, if HasAgreedToTermsOn has a value but HasAgreedToTerms not?

@sleupold I believe the reason to leave the value is that you can infer "last agreed" by this.

IN this case, I would store "HasAgreedToTermsVersion" instead of "HasAgreedToTerms" and compare with PortalSetting "TermsVersion", which would be increased by the resetButton.

What is the benefit of just keeping the past 10 records?
IMO success records should only be kept, if there is a concrete need - otherwise logging should turned off.

@sleupold This is a good idea. @donker Possibly disabled by default? Thoughts. Users could turn this on, but the data is in fact recorded elsewhere

OK. Done. It's gone.

IMO this distinction is not correct, it doesn't cover superuser profiles properly.
You should distinguish upon @portalid parameter, whether to delete portal specific properties (positive value) or all properties (PortalID is Null or -1). It depends on Userportals records, whether to call with portalID (other userportals record with other portalID exists) or without (otherwise).

This looks really great, and thank you for the contribution! It's going to make a lot of people quite happy to see this in the release notes for v9.4.0!

Can you easily move the sql changes into the main 940 file? This early in the cycle I'd rather keep them in a single file, but since we really don't have anything defined for sql changes it's really just my personal preference for release management and upgrade performance and not a required change at all.

/AzurePipelines run "DNN [Publish Artifacts]"

Result: CI task didn't set the correct version, so I cancelled the build. Will trigger it again shortly after another test build runs.
