MAES, its VTAM server components, and its TCP/IP server components, will optionally operate as APF-authorized z/OS programs. Special capabilities, such as RACF sign-on verification, are only available when these programs are authorized. When MAES is unauthorized, these capabilities will be unavailable.
When MAES is executing as an APF-authorized program, your applications (KBs) and associated programs that are accessed via STEPLIB and MAESHPO DDs will need to be placed in authorized libraries. Your applications (KBs) and programs will be executed in unauthorized contexts. So there is no capability for your applications (KBs) and associated programs to perform authorized activities.
When MAES VTAM capabilities are established in an authorized context, more efficient authorized path VTAM facilities are used. If MAES is unauthorized then this performance improvement is not obtained.
