Applications running on a distributed platform can use either of the following options to call ACF2:
Applications, such as servers, can invoke the USS R_admin callable service (IRRSEQ00) running on z/OS to manage and retrieve ACF2 security
Applications can make a LDAP call to the LDAP Server running on z/OS which provides an inbound Lightweight Directory Access Protocol
(LDAP) interface to ACF2 z/OS. The LDAP Server running in z/OS provides an interface to the ACF2 and Top Secret security
databases using the ACF2 and Top Secret backend modules.
