Topic on Extension talk:OpenID Connect

I had a couple questions regarding usernames:

First, I've been using $wgOpenIDConnect_UseRealNameAsUserName set to 'true' for a wiki and am wondering if the 'real name' that is provided by the issuer changes in the future, will the username in MediaWiki be updated to reflect that change?

And I'm considering changing to use the 'email name' for the username instead, but simply setting $wgOpenIDConnect_UseEmailNameAsUserName to 'true' instead of the 'real name' option doesn't seem to update the username on subsequent logins. Is there a way to do that? Thanks!

The username config variables are only used when the account is initially created. The username will not change automatically when the real name changes or if you switch to a different username source. You would have to use another extension (e.g. Extension:UserMerge) to manually rename the accounts.
