Problem Description

Hi,

Our internal IDP, uses the propery acr_values as a set of arbitrary values that the client and idp agreed upon to communicate the level of authentication that happened. This is to give the client a level of confidence on the qualify of the authentication that took place.

There are no "official" values for them. They should be communicated via the acr_values_supported parameter of OIDC discovery response. Please see OpenID Connect Discovery 1.0 for more on this.

Proposed Solution

Add new, non-mandatory, config field in OIDC connection.

Alternatives Considered

Additional Information

I will create the PR for this.
