We are planning to upgrade Penatho 4.8 to 5.3.
One issue I noticed is Access control for folder level access. We implemented Single sign on and the portal passes the roles to Pentaho.
For various folders access, the access details are manipulated in hibernate database with the table PRO_ACL_LIST tables.

But Pentaho 5.3 doesn’t uses PRO_ACL_LIST tables for folder level access. In My case I'm not storing the Roles and users in Pentaho security, instead roles will be passed from the portal as SSO is configured.

How I can implement Pentaho 4.3 similar ACL system in Pentaho 5.3.
