I add users in authentication.conf. I push them to SH. The updated file resides on .../primary/..
But when i reload (which i have to do for some reason), a new copy of authentication.conf is automatically created and is placed in ../etc/system/local/
this system/local copy overrides the one in primary.
Now i have to delete this system/local copy every time i add users to see newly added users in UI.
