Hi Piotr,

sorry for the late confirmation but this is indeed not possible, the group permissions are all configured in the security.xml file but we also have a cache to know when a user was updated to push the latest updates throughout the cluster

This is located in the C:\Skyline DataMiner\Files\SyncInfo folder

So it means if you update users manually these are the 2 locations that you need to keep an eye on, unfortunately we don't have a script to bulk edit these things (yet)
