EXTSEC

Specifies whether calls are to be made to external security.

If you specify YES or UNIQUE, external security calls are to be made. The difference between them is in the resource names that are used.
Specify EXTSEC=UNIQUE if you need separate rules for one or more regions. This causes external security calls to use the "RMO#." prefix, where the # sign is replaced with the region’s SYSID= value.
Note: For EXTSEC=YES or EXTSEC=UNIQUE to be in effect, the started task must have been started at least once since the last IPL.
If you specify NO, external security calls are not made.
For EXTSEC=YES or EXTSEC=UNIQUE, you can also specify whether a list presented to a user contains all elements (NOLIMIT) or only those that the user is authorized to see (LIMIT).
The default is LIMIT.

Syntax:

EXTSEC=NO (YES,LIMIT) (YES,NOLIMIT) (UNIQUE, LIMIT) (UNIQUE, NOLIMIT)

Default: NO
