KI 1452 Error "Sign in failed, email already taken" when logging into UiBs Gitlab

When you try logging in to UiBs Gitlab (https://git.app.uib.no) you get the error "Sign in failed, email already taken".

Your user account on git.app.uib.no is no longer linked to your Dataporten/FEIDE-user. This can be remedied by the IT-department using information provided by you.

For this your unique user ID from Dataporten is required, you can obtain this user-ID by using your UiB account to log in at https://minside.dataporten.no

After doing so, you will see this screen, with "Dataporten user identifier"/"Dataporten brukeridentifikator". This string can be copied and attached to an issue in UiB Help.
