Add Webauthn policy to Keycloak
Currently, the Webauthn policy gets overridden on every single
terraform apply which sucks a lot!
We urgently need to manage this via Terraform properly. It needs these PRs to be merged prior:
- https://github.com/mrparkers/terraform-provider-keycloak/pull/385 (not as urgent as 356)
@klausenbusk Could you take a look at your PRs over at the provider's side?
