Attempting to execute RACF commands via LDAP using the CMDLINE parameter fails:
cmdline=DEFINE ALIAS(NAME XXXXXXXX) RELATE(USERCAT.CATXXX))
This command returned the following error message:
LDP1999E Error issuing command with R_Admin, <>
The command line processing is only for ESM (RACF, ACF2 and Top Secret) commands. Define Alias is a z/OS command not an ESM command.
There is a Broadcom LDAP parameter that will create an alias when a TSO user is setup called CreateAlias. More details can be found in LDAP documentation section Database-Specific Options (RACF).
