Multiple issue I'm facing on Alfresco Process Services

[matrix2526]

 Dears All, 

I'm trying to create a Proof of concept (PoC) implementing the below workflow and I faced the following issues:

1- I link Alfresco Process Services with our active directory then I created groups in Alfresco Process Services Organization and define the group and sub-group managers. then in the workflow, I assign the "review and approve" user task of the line manager to process initiator's (primary) group manager. but when I tested it, it doesn't work.

2- I need to assign the other "review and approve" task to the department manager of the process initiator, not the group manager.

3- I need to assign a task to one of the employees in the HR department using some algorithm.

4- I need to use REST call task and send the process initiator information to the REST service.
