Unable to log in via ORCID

[felixhelix]

Hi,
I'm testing the ORCID integration of OJS and want to publish a detailed description for our journal editors.
I was able to register with my ORCID account. But when I log out and try to log in again via ORCID, I am always redirected to the page asking

" Do you already have an account with Journal of XY?
-Yes, I already have an account.
-No, I'm new to Journal of XY!."

However, if I choose "Yes" I need a valid OJS account with password.

: (

If the user already exists, and so "Yes" is a valid option, the account is successfully connected to ORCID. In the following I can log in using my ORCID credentials.

Any ideas?

Your's
Felix
