Yes. However, if an ESM is active, you have to issue the CMS RPIVAL command since checking the CP directory isn't useful. I recognize that issuing RPIVAL is problematic for Linux and am working to address that problem in a future release of z/VM. Each ESM product does a product-specific thing inside the RPIVAL command. The RPIVAL program that comes with RACF/VM simply issues a diagnose 0xA0 subcode 4 (see the RACF/VM Macros and Interfaces book). What you do if another ESM is installed, is up to the vendor - ask them. And before you ask, no, there's no [programmatic] way to tell which ESM is installed. Diagnose 0xA0 subcode 8 only tells you an ESM is present - not which one. Using VM for Linux authentication and access control purposes is an area of intense interest to me.
