[vkush]

Configure AAI mechanisms in Repo4Cat using OpenID Connect.
See here:

• https://doc.nfdi-aai.de/
• https://doc.nfdi-aai.de/incubators/

TODO:

• authentication via institutional account
• authentication via ORCID (see https://guides.dataverse.org/en/latest/installation/oauth2.html and https://orcid.org/content/register-client-application-0)
• activate and test OpenID Connect in the demo repository
• activate and test OpenID Connect in the central repository

Is "authentication via institutional account" the same as "authentication via eduroam account" or is the latter another item for your TODO list?

In my opinion this issue and updating dataverse are most urgent.
