Question on FTP access to libraries and folders

I have created a user id with no access to the system, that is, they cannot
sign on to the interactive systems.

Access has been limited (or so I thought ) to one library LIBXX and one
shared folder MSBI.

I created a JOBD where LIBXX is the only library on the library list and
this is the JOBD assigned to the user.

I then FTP'd to the system from the PC command line and did a DIR. The
system lists objects in QGPL and some other libraries but not LIBXX.

Investigating the FTP job, I found the JOBD being used is QTMFTPS in
QUSRSYS which presumably where the other libraries are coming from.

What do I need to do to have the FTP job see LIBXX and the SHARED folder
only?

TIA
