User directory for file server managed node

Hello,

I’m making some test in a lab to understand interactions between UCS instances.
I created the main instance (ucs-9771) and a first samba share on it (shareval)
I created two users ypa and bko.
Everything is working correctly (but note that no user share exists)

My objective is to have the file server on another server.
So I installed a second node (ucs-2586) that is now connected to the main instance domain and installed “Windows-compatible Memberserver” from the App Center.
I created a new samba share for this new node (shareval2)

But I don’t understand why a user folder is created on this node and automatically displayed as shared (the front window is a VM logged with bko, and the back window is another VM logged with ypa).
