QPWFSERVER authorization list in the QSYS.LIB file system
The QPWFSERVER is an authorization list (object type *AUTL) that provides additional access requirements for all objects in the QSYS.LIB file system being accessed through remote clients.
The authorities specified in this authorization list apply to all objects within the QSYS.LIB file system.
The default authority to this object is PUBLIC *USE authority. The administrator can use the EDTAUTL (Edit Authorization List) or WRKAUTL (Work With Authorization List) commands to change the value of this authority. The administrator can assign PUBLIC *EXCLUDE authority to the authorization list so that the general public cannot access QSYS.LIB objects from remote clients.
