@mrkvon

Actually logging in with NSS account use the RS256 algorithm.

With #1698 being resolved we can also login with CSS ans ESS account that are using ES256

• is there a missing information in openId-configuration ? This is not displayed above
• Are there any reason to move NSS to use ES256 in replacement of RS256 ?
