OSGi: User Admin Service howtos

[Santiago Aucejo]

Is there any good tutorial or example implementation for the use of the (Felix) UserAdminService.
In our app, i have to use the UserAdminService for authentication and authorization and connect that with an OpenAM Repository.

I´m new to OSGi and searching for a good tutorial to get started with the UserAdminService and haven´t found any by now.

thanks for helping,
Santiago
