The “Built-in OAuth server” auth template uses IdentityServer4 but IdentityServer4's support ends at the end of the year 2022. For this reason, starting from PowerServer 2022 R2, the “Built-in OAuth server” auth template will no longer be available.  If you have implemented the “Built-in OAuth server” authorization in your project, there are three possible migration paths:

  1. (Recommended) Migration Path #1: Switching to the “Use built-in JWT server” auth template
  2. Migration Path #2: Switching to the “Use external Azure Active Directory service ” auth template
  3. Migration Path #3: Switching to use Duende.IdentityServer for OAuth

Please refer to the attached PDF document for more details on each migration path.
