I was trying to write OAuth2 plugin for Camunda , I followed the interface
org.camunda.bpm.engine.impl.identity.ReadOnlyIdentityProvider
and I followed the process for LDAP, to replace the auth and get user list from Oauth2 provider and also the groups.
https://docs.camunda.org/manual/7.7/user-guide/process-engine/identity-service/
Is there any implantation is there for Camunda OAuth2 ?
Which Camunda deployment and which OAuth provider are you using?
Camunda offers an example for keycloak on GitHub: https://github.com/camunda/camunda-bpm-identity-keycloak The implementation for your provider would likely look very similar.
Have not QAed this, but you might also find inspiration here: https://github.com/hobbstech/camunda-spring-oauth2-plugin/tree/master/src/main/java/io/github/hobbstech/camunda/oauth2/plugin
