Description

Kelderby's first single sign-on weekend (OPS-51): nine people (Rotterdam 5, Antwerp 3, Ghent 1) got "No account for this sign-in". The import had their private or old email; Entra ID sent their Kelderby UPN, so sign-in found no person to match. No account is ever made at sign-in, so Kelderby's IT made each of them a new account on Saturday (SUP-1260). That gave nine second records, with their roles and waiting requests left on the old ones. It will happen again at the next 22 depots.

Proposal

Part of Kelderby go-live hardening in Emargen.

All nine merged with Merge duplicate people by 11:30 (SUP-1264).

Matching on Kelderby's employee number at first sign-in when the email doesn't match: in Kelderby go-live hardening; the email/UPN comparison is its first slice. This stays open for the account team.

Kelderby sent the UPN export for Duisburg, Venlo, Liège and Breda. Matching it against the import before Saturday.
