You update oeablSecurity.properties to enable OAuth2 and tell PAS for OpenEdge how to validate tokens. This includes pointing to the OESECTOOL key endpoint and enabling JWT-based authentication.
  1. Edit oeablSecurity.properties for the web applications.
    Linux:
    instance/webapps/web-app-name/WEB-INF/oeablSecurity.properties

    Windows:

    instance\webapps\web-app-name\WEB-INF\oeablSecurity.properties

    Example:

    C:\OpenEdge\WRK\oepas1\webapps\ROOT\WEB-INF\oeablSecurity.properties
  2. Set client.login.model to oauth2 to enable OAuth2 for a single web application.
    client.login.model=oauth2
  3. Save the file.

For more information about client.login.model, see Enable ABL application authentication.
