To use external user db in camunda project

Hai, I am trying to use an external db for user access in camunda project and i don’t want to use the camunda db for identity service.Is it possible to override the camunda user db. I need to access users from another application db.It need to be read-only
I read about it in this post:
https://groups.google.com/forum/#!topic/camunda-bpm-users/u4777peJYwM
I am trying to achieve this.Is it possible to configure it using a process engine plugin and i need to know how to set its configuration properties??

Hi there,

Could you try creating a processEngine plugin just like the LdapIdentityServiceProvider which is shipped with Camunda?

Hope this helps!
