When resetting a password, you get the 'centralauth-account-exists-reset' message:
"The username Hashar is not registered on this wiki, but it does exist in the
unified login system."
This message is definitely missing a link to the user homewiki which is the only place where the password can get reset as I understand it.
I figured out my home wiki by having to browse Special:CentralAuth/Hashar then did the reset there.
