esfadmin is a command-line utility that calls the ESF Admin API to request administrative actions against ESMs. It is a part of Studio Enterprise Edition for UNIX and Server Enterprise Edition, and can be found in the \base\bin directory.
One advantage of esfadmin is that it can be used to perform batch updates to an ESM, typically as part of a script. Another is that you supply all its configuration information on the command line, so you do not have to configure your MLDAP security manager in MFDS with an LDAP administrative user ID.
