Cannot install security profile on imac Late 2015 with OCLP Sequoia 15.7.1

Hi, since I installed OCLP Sequoia 15.7.1. de imac security is not allowing me anymore to use my companies remote desktop office environment. I tried many things like re-install the bootloader, update the rootpatches, but so far no succes. Before I go back to OCLP Catelyna , any clue about how to get this fixed within OCLP Sequoia?
