BE: Add "Last login date" to Billable Members API
Problem to solve
There is no way to view the Last Login Date of your group members on .com (either through the GUI or via the API)
Intended users
Further details
Since we don't allow Admin access on .com, Group administrators need a good way to view the Last Login Date of members in their group. Currently, you can sort by oldest_sign_in and recent_sign_in, but it doesn't show the actual date of the login.
Proposal
- Add Last Login Date to the Group Member API
- Add a Last Login Date field to the Seats tab on the Usage quotas page (not in scope for this issue, being handled via FE: Add "Last login date" to Billable members l... (#370930 - closed))
Permissions and Security
I believe the 'oldest_sign_inandrecent_sign_in` is currently restricted to the Admin API, but it would make sense to add it to the Group Member API as well.
What does success look like, and how can we measure that?
Group Owners on gitlab.com are able to view their user's Last Login/signin Date.
What is the type of buyer?
This should be a Core feature. Everyone on .com should be able to effectively manage users in their Group.
Development Notes
NOTE that last_sign_in_at is not the last time the user logged in. That is current_sign_in_at. last_sign_in_at holds the previous value of current_sign_in_at.
Availability & Testing
Unit tests for the added functionality and perhaps a feature test (or will later be included as part as an assertion in one of the e2e tests that cover that general area as well)
