Description

https://meta.wikimedia.org/wiki/Special:CentralAuth/DeannaPeter3 was created only locally on enwikiversity without any accounts. Why did this happen? If there's a method of reproducing this behaviour, this will gravely disrupt our ability to address spambots as they would not have any log on loginwiki for us to monitor the spambot issue globally.

Event Timeline

I just discovered a very similar case when locking [AureliaSperry](https://meta.wikimedia.org/wiki/Special:CentralAuth/AureliaSperry). Nothing of interest in the logs at a glance (no obviously related exceptions, fatals, …).

Interestingly also no CentralAuthCreateLocalAccountJob Job seems to have been schedule: hoo@mwlog1001:/srv/mw-log$ grep CentralAuthCreateLocalAccountJob JobExecutor.log | grep AureliaSperry yields no results.

Doesn't seem to be related to SUL3

I assumed that because T368230 was related to SUL3—after T363695 disabled CentralLogin on loginwiki—this would be as well.

This task existed long before SUL3, therefore the issue reported in this task is probably unrelated. I can imagine that T394732#11362672 explains some of the issues, although I'm not sure if that's true for all affected accounts.
