Failed to verify user: user does not exist [uid: 0, name: OAUTH_USER]

[sebastian-sauer]

Description

Analysing our gitea log files we see a lot of the following log messages:

routers/web/web.go:121:func9() [E] Failed to verify user: user does not exist [uid: 0, name: OAUTH_USER]

It looks like this is a log in web.go:

log.Error("Failed to verify user: %v", err)

Having an error in the logs for every wrong auth attempt could explode the log files and hide other important messages.

Additional question: is the OAUTH_USER a special user?

What are the logs around it? Is there any one trying to use "OAUTH_USER" as user name to try to login?

I only got the error logs for this system and nearly the only output we get is this log message logged multiple times.

But while digging through some other issues i think this is a duplicate of the following issue:
